Causes of Cat Aggressive Behavior

Updated on February 05, 2016

There may be several causes of cat aggression

Narrow down why your cat may have turned out aggressive

The most obvious physical causes of aggression in cats is pain. Having worked at an animal hospital, I have seen my fair share of aggressive cats. In many cases, the cats proved to be far more aggressive and damaging than dogs. As a veterinary assistant, you surely do not want to deal with a very angry cat. Fortunately, special restraint techniques make treatment possible, sometimes requiring the help of others.

When it comes to aggression issues with cats, underlying physical or behavioral problems must be addressed. There can be various causes and therefore, identifying the triggering factors may help ease and/or solve the aggressive issues all together.



Physical causes of Cat Aggression

Before assuming your cat is just plain mean or aggressive because of some behavioral problem, it is important to rule out some medical condition. If your cat is usually friendly and now out of the blue is hissing, does not want to be picked up and this is totally out of character, assume a painful condition or some other underlying physical problem known for causing aggressive displays.

  • A non visible wound

Anytime your cat appears to be aggressive for no reason, a veterinarian visit is a must. Somewhere must be hurting and the cat may scratch or bite if handled improperly. The source of pain therefore must be investigated. Many times there is an open sore or an abscess not visible under the fur. My cat one day was hissing and growling and we had no clue, only a day later we noticed one of her nails had grown so long it was embedding in her paw pad!

  • Chronic conditions

Chronic conditions such as arthritis, dental disease or poor eyesight may cause cats to become grumpy and unwilling to be touched. Have a veterinarian screen your cat for any underlying health disorders. While cats tend to hide their pain because this makes them vulnerable, when there is pain, the cat is likely to change attitude.

  • Hyperthyroidism

Cats affected by this disorder may exhibit behavior changes along with increased drinking, increased urination, weight loss, vomiting and diarrhea. Behavior changes may consist of aggression, nervousness, and hyperactivity. Worth running a thyroid panel if your cat has had recent behavioral changes and you cannot find a reasonable culprit.

  • Rippling skin disorder (Hyperesthesia)

This is a condition that is not very known. However, many cats seem to be affected. Affected cats will display an odd behavior: their skin on their back will twitch and the cat will run as if bothered by something. The cat may then turn around and try to bite or scratch its back. The cat's eyes may be dilated and the cat may vocalize disturbed. Upon petting these affected cats the skin on their back may twitch and they may turn aggressive.

  • Rabies

If you encounter a stray cat that is aggressive ,stay away as it may have rabies. Consider rabies as well in unvaccinated cats that appear aggressive and that are kept outdoors in contact with wildlife. Should you encounter an aggressive stray cat, call animal control. They are best equipped to restrain such cats and have them evaluated for Rabies. While rabies is rare, it is such a serious disease that you must rule it out if an unvaccinated stray cat bites you or scratches you.

Psychological Causes of Aggression in Cats

Once you have rules out medical causes for aggression and your vet gave your cat a good bill of health, it us time to consider behavioral problems. Important questions to ask are: any recent changes? have you moved? new partner? new cat in the home? a new baby? new furniture? new routine? new construction workers across the road? Cats are creatures of habit and anything that changes their routine makes them stressed.

  • Redirected Aggression

This is a form of aggression caused by an overstimulated cat. This may occur when a cat sees out from a window another animal such as another cat or a dog and then suddenly attacks his owner or another pet. Such cats may be difficult to treat, many times requiring covering all windows and doors or placing the cat in a dark room to calm down.

  • Unfamiliar scent aggression

Many times right after taking a cat to the animal hospital, owners would call us because their other cat at home would start attacking the sick cat. This is a common instance, and it is due to the fact that the cat left at home is disturbed by the other cat's smell. Many times this was solved by bringing both cats at the hospital when one was sick or by passing a scented towel on both cats so they both smelled the same.

  • Rough playing aggression

Many times young cats and kittens may be thought to be aggressive while all they are doing is playing rough. A cat or kitten that attacks the owner's ankles is simply acting out of prey drive. In other words the owner's feet or ankles are thought to be prey and so the cat chases and scratches. Most cats seem to outgrow from this form of play aggression, however, a good remedy is to toss a toy at the cat upon stalking you in order to redirect his attention.


  • Intolerance to being pet aggression

Some cats will tolerate being pet for a few minutes and then they will lash out when they get tired. In this case, it is very important to anticipate his behavior by reading physical cues suggesting he is about to lash out.Before reaching his intolerance point immediately put the cat down and give a treat. Repeat by making the petting sessions longer.

  • New mom aggression

Your sweet cat may turn into a lion once she has hada litter of kittens. Most new mom's aggression regresses as the kittens age. Try to keep her quiet and avoid disturbances. This is just a natural instinct to protect her babies.


  • New cat aggression

You just adopted a new cat and your older cat will not tolerate the new arrival. Threatening growling and hissing takes place. This form of aggression usually regresses with time. Always make introductions slow and do not force the two to get along. Sooner than later with no pressure, the two will begin to accept each other.


As seen there may be a multitude of causes for aggression in cats. The best course of action is to have all medical causes ruled out first and then deal with the behavioral issues.

      I have a male cat for two months, He is been neuter but his aggressive behavior has not change. He watch me as I walk and then attack me bitting and scratching. If I try to scare him then he become more agrassive. He can jump as high as my head to attack. I don't know what to do.

      Seems like he is confusing your feet for a threat. I had a cat do this especially when wearing a certain type of shoes of when wearing different cloths. Indeed scaring him makes him worse because most likely he is attacking because he is afraid. Maybe you can try to spray him with a water bottle right away before he does this? After the first few tries he should be giving up and understand not to mess with you...

      we have a crazy orange cat that is neurotic as it is and if he gets a whiff of our dog and sees another one of our cats he will attack the cat it's like 2+2=5 or something.

      My 3 year old cat- Zeke was always very affectionate and happy. He purred constantly and had tons of energy. Right after we moved, we adopted cat #2- Delilah and ever since then Zeke has been ignoring me, hissing at me, growling, batting his paws etc.

      Zeke generally doesn't mind Delilah unless I'm trying to pet him while she's near. It's very strange, but it seems as though he's just very jealous; when I pet Delilah, he tends to be creepishly standing in the corner of the room, staring. It has been almost 9 months since we've gotten Delilah, and Zeke's behavior is still crazy. I have only heard him purr twice in the last 9 months. Do you think there is more than just new cat aggression going on?

      Cecci, try to toss treats or something the cat really likes every time you pass by, if you do this frequently enough the cat may start associating your walking by with good things

      Adopting a new cat may totally put upside down the relationship a cat has had with its owner. It may be stressful and I have known of cats refusing to eat upon dealing with a newly adopted cat.However this seems to be going on for long. I would suggest a vet visit to rule out anything medically wrong. Perhaps this article may help shed some light on your situation>

      Dear,

      Please help. This cat entered my appartment two weeks ago, and just came to me sitting on the couch. I petted it a little and she was purring non stop. I went to sleep that night and she slept with me on my bed. She never left my appertment after that day and I kind of fell in love with her. My girlfriend who has experience with cats says she can't be older than a few months.

      Two weeks later, she now has food, a litter bin which she started to use imediatley after I got it and toys to no end. Yet she still continiues to become more and more aggressive. You should see my right arm...

      It's probably all my fault having never had any pets, and mistaking her increasing agressiveness by too much energy and stimulating it by throwing her the toys.

      I'm having trouble discipling her since I love her and want her to be happy and comfortable. What should I do?

      I've taken my cat to a new vet since her original one was not available, he said she needed a few treatments for things like eye infection and worms in her tummy, I also asked to shave her but they had to tranquilize her in order to do so because she didn't allow them to touch her. the vet asked me to come the next day (today) so that shed regain her consciousness, I did, and just as soon as I entered the clinic he asked me if my cat was normally moody and doesn't like new people, then when he opened her cage she started growling and hissing and screaming loudly I almost couldn't believe it was my calm cat. She was shaved to zero and when he put her on the table she immediately came and sniffed my clothes and stuck to my side not letting go. When we were in the r on our way home, she couldn't stop jumping and growling and screaming inside her box which really scares me, now it's been around 8 hours and she's still staggering a bit and falls down every few steps, she was fighting with every object in the room and slamming herself against the walls which REALLY broke my heart to see that, i decided to leave her alone in the room after ive moved everything away from the room, I peeked through the door and found her sleeping in the middle of the room, my question is when's this aggressive behavior going to stop? It's really very strange as i never seen or heard my cat growl and hiss LIKE THAT.

      plz help me I need her back and I'm very worried!

      Sorry my reply comes late we are on different time zones, I am in Europe at this time. I am sure you are worried! Such drastic behavior changes can be scary and heart breaking indeed. My cat too took a long time to stop staggering after the anesthetic. Being a Persian she was shaved down as well and I must admit her behavior changed too after the shave down. She was shivering all the time and would sleep all day instead. I told my vet and he told me that cats feel odd without fur. I still think she was probably scared and cold

      I think your cat needs some quiet time for a few days. Try to keep her in a quiet, dark place and let her relax. if possible. Some cats become really lethargic after the anesthesia while others react by becoming hyperactive and aggressive. It may just be a matter of time, keep her safe and monitor her every once in a while without interference much.

      If it will make you feel better Alley Cat Allies claims: ''The cats will be groggy as they recover from anesthesia. The anesthesia could have hallucinogenic effects and cause some cats to overreact to normal stimulation or to become aggressive. The anesthesia will wear off after about four to 24 hours.''

      Thank you so so so SO much for your time! My cat has been better since my last post! But Is still afraid of objects and jumps back when she gets closer to them such as chair legs and wires, is it because they shaved off her whiskers as well? So she cannot sense the distance between her face and the object? I carried her for a tour around the house so that she remembers and picks up the smell of it.

      Mine is a Persian as well.

      You really made me feel better! Thank you for the link as well, it's very informative!

      Giving us some of your time really means A LOT!

      You are very welcome~! Only time should tell if the jumping at objects is still due to the anesthetic or feeling odd without whiskers and hair. If you are really concerned pick up some Feliway (synthetic hormones that gives cats a sense of well being and familiarity) from you local pet store, it might help.

      Happy you are feeling better, hope you Persian will be back shortly to her usual self. Cook her up something that smells real good in your kitchen (boiled chicken or boiled fish) so she feels more comfy and tempted to come out. Best wishes!

      Think of any possible changes that could have occurred. Did you take the dog away lately for a trip to the vet, to a boarding kennel or some where else? What triggered the first attack? It could be your cat is not feeling well and does not take well your dog's rambunctious energy. What happens exactly? Is your cat quiet and your dog is too exuberant and she asks the dog to leave her alone? If so provide your cat with some high furniture she can go to when she needs quiet. It could be that getting older she does no longer feel like playing with the dog or that the dog caused her pain. Could be she has a touch of arthritis? Does she start the attack or does the dog trigger it? Watch the dynamics carefully...

      No, there hadn't been any changes. They both have lived with us for about six years now. Our dog isn't really that playful, when they would play around it was the cat that began the playing. One night our dog was undr the table and she was walking around the house when all of s sudden she attacked him. I tried seperating them, but she would do what she could to strike again. She was very aggrivated to the point that she bit me and scratched me severely. The dog has always left her alone, and especially after that event he trembles at the sight of her. We had to keep them in separate rooms. It was all very unusual. Is there anything else you can think of?

      Hmmm... sort of odd, I think the best bet is a vet visit. Being towards her senior years, anyhow she should have a yearly examination with blood work. Mention it to your vet and see if he thinks of any tests to run. Re-directed aggression is also a possibility, if she has access to windows and sees other animals. Best wishes!

      Just been attacked by my loving 3year old cat. Just walking though the room and boom, claws out hissing and chasing after me and trying to attack me. I’m locked in a room right now and I mean I’ve lock the door because she knows how to open them. This is the second time this has happened. Everything was calm and she just went wild. any ideas what’s going on with her and how to calm her. I need help right away! Thanks!

      Sounds like a case of redirected aggression but can also be something else going on. Somebody should find a safe way to close the cat in a dark room and allow her to relax for a few hours. Are you wearing always the same type of shoes when she does this? I have noticed my cat used to do it when I used to wear this special pair of slippers.

      I adopted a Snowshoe Siamese-mix 2-1/2 weeks ago from a shelter. Because he developed a cold, I quarantined him from my other two cats for the two weeks recommended by my vet. At the end of that time he came down with conjunctivitis and is now quarantined a further two weeks. I've been giving him playtimes but, apart from those times, he refuses to come near me. When he first came home with me, he slept on the bed with me and came up to me but he seems to have a problem with biting. I first dealt with this by saying "Ouch! No!" and tapping his nose but he began getting an angry look in his eyes and would lift a paw to me and act like he wanted to bite again. I then started using a squirt bottle after saying "Ouch! No!" and would squirt him in the face a bit. He's still supposed to be receiving ointment in the eye but runs from me anytime he thinks I'm going to pick him up to give him medication. I really want to have a good bond with this cat and hope he'll be good with my two females. Can you suggest anything?

      I meant to add to the above comment that, prior to coming to live with me, Leon was taken in off the streets by a woman with MS who became too ill to continue caring for him after she had him two years. He is now between 4-5 years. We don't know what his first years were like.

      My husband and I have 3 cats Stripes Deliah and Lily ( all female) We just moved into a new house and Stripes and Deliah are adjusting fine. Now lily on the other hand has become very aggressive now she is not usually an aggressive cat but when she was 3 ( she is 8 now) there was a short time where she did become aggressive with us that passed after we took her to the vet then a few days later went on vacation and left her alone for a week. Now back to the presant we have been able to get near her but then she decides to guard an area and will not let us get by this has been a problem since she has been "guarding" our bedroom. We have been able to chase her out but she goes into fight mode and attacks as she is leaving. We are at a lose as she is generally a very friendly cat ( except for one episode when she was 3).

      I have two cats one is only just over a year and the other is 5 months. When i first brought the younger one home i had trouble with the older which is what i expected. After a couple of weeks they were getting along really well and the older one was even acting as a mother towards the younger one.

      But for the past couple of weeks the older one has been quiet irritated by the younger one and it is slowly getting worse and sometimes even acts out towards me and the other members of my family. What do you thing is causing this erratic behavior?

      we left on a mini vacation for a total of 3 days. our cat which i would consider to still be a kitten, (i don't know her exact age because that is my girlfriends thing) but she has been jumpy and a tad bit aggressive, the aggressive could be considered playful to some. she wraps her paws around the wrist and wants to nibble on your hand. also when doors a shut she whines a little. i know this all may sound normal but she didn't really do it before we left. she had plenty of food and water and i also left the radio on. any help would be great because again this is gonna sound stupid but...wait very stupid..but i watch a lot of ghost tv shows and it seems like the symptoms of an animal haunting...ugh. i know laugh it up, someone has to understand.

      nothing is majorly wrong, shes not hurting anyone, its not out of control, it just weird me out and i wanna know if it is common for them to act like this after a few days alone.

      thx in advance

      Who was she left with for those three days? If she was left alone your absence may have upset her. She may be afraid of being left alone again, thus the whining when the door is shut-. The nibbling on the hands may be an equivalent of a ''love bite'', but can't say for sure without seeing her, here is a link, read under love bite:

      http://www.healthypet.com/PetCare/PetCareArticle.a...

      Being left alone she may be making up time and getting stimulated more than usual when being pet.

      I have 3 cats at home 2 boys and a girl. 2 days ago my boyfriend and I decided to buy another cat with her 2 kittens.The mom cat was very sweet. When we came home and introduce my new cat with the old once, the cat mom became aggressive, she attacked my 3 cats.I don't have any idea why she became aggressive, is she over protective because of her babies? or she doesn't like to be friends with my cats at home? I don't know what to do. I really felt bad because all my 6 cats including the 2 kittens are now in their cages. I cant let them walk around my room because I'm scared that the attack of cat mom will happen again and since I'm just renting,the space of my room has just a limited space. Please help me, I want them all to be friends and don't want them to put in a cage forever.please help me.Thanks!

      Only time will tell if these cats will get along..give it some time, do not force interactions, as the kittens grow the mom should become less protective..as days go by they should get used to each other's presence, the first days are always the most critical..

      Hello, I have a female cat here that is about 3 years old, she is now showing a lot of aggresion twoards one of my dogs (a female) and will lash out at people with out warning if u get too close. I have a friend that lives with me and will be attacked for no reason. I have a total of 2 dogs and 4 cats. The other 3 cats are about 1.5 years old, had them since they were born (there mother left them, ran away out side and have no idea were she is) and my 3 year old cat was a sister of the mother cat and took them as her own (after the kittens were about 8 weeks old is when hte mother cat ran away). We have no reason why she is aggressive. Also when she gets like this the other cats get upset and they all will hide in my back room (keep all the food and litter boxes back there away from dogs), i believe that is like there "safe room" from harm (and will attack any who go near). My 3 year old cat does not attack me but will others. I plan on taking here to the vet. and getting her checked out and getting her shots again and possibly declawed (is declawing a cat bad for a cat?). I kinda think it might be she feels threaten by one of my dogs and want to protect the other cats or something). I could really use some advise. Sorry that this post is so long =p Thank you for reading.

      I think when a cat changes behavior out of the blue, there are chances an underlying medical problem may be behind it. She may feel more vulnerable and therefore is more defensive. Cats also can get stressed from a dog's boisterous behavior, and if the stress is too much to handle they will suffer from re-directed aggression (they basically attack anything in sight)I think the vet is your best bet to start so you can rule out medical causes and go from there...

      I have a 1 year old male cat not neutered. Sometimes he gets out of the house and goes into our back yard. When I went to get him from the back yard one day and picked him up he attacked me by digging his nails into my face and head and he bit my lip. He doesn't show signs of Rabies and he is usually a mild manured cat who purrs and cuddles with me all the time. I don't understand what could have happened. Right now he is in my basement and I am afraid to let him come up cause I don't want him to attack my children.

      Sounds like he may have been startled by something and over reacted. If he was nervous in the first place, he may have felt 'overcharged'' and discharged his stress on you. Give him some time in a dark room and then try to let him out and see if he is back to norm. Best wishes

      I have four cats, two male and two female. One of the males and one of the females just came to live with me and the other two cats about five months ago (all four had lived together prior to this, for about two and a half years. I got them all when they were kittens but due to an issue with moving I couldn't take all four with me at once) All four of them are four years old, fixed and have had their shots. I've had cats my whole life so I was expecting the first few weeks to be very tense while they all got used to one another. But now, the one male (who moved in five months ago) is being tormented daily by the two that always lived with me. He is very sweet and does nothing to provoke them. It has gotten so bad that he stopped using the litter box until I bought him his own. I've noticed the one female (who has been with me the whole time) is very aggressive towards him. If he is trying to eat at the food bowl she will attack him. It has gotten to the point that he will cautiously enter a room, look around for her and then run and jump onto the counters to avoid getting smacked by her. She has chased him into the bedroom while I was sleeping and he jumps onto the bed and countless times she has clawed my face, head or legs in an attempt to get him. She doesn't care to be held or pet, it just seems like his presence bothers her and infuriates her. But the female that came with him doesn't get the same treatment from the other two. They leave her alone.

      Confused 5 years ago

      Our dog (Shi Tzu mix) and cat have lived with us for over 5 yrs. Cats been with us for 7. We did have another dog (husky mix), who died 4 yrs ago.

      Our cat will aproach the dog... snuggle up to her... then suddenly attack. Other times she simply hisses and attacks or pounces. She is neutered (They both are). Cat is an indoor cat, never allowed out. She's too fat to jump up to most of the windows... but I know we have mice in the walls (Live on a farm).

      I know this is re-directed aggression, but nothing we've tried has helped, including separation or spraying. When we separate her... she scratches at the door, or the walls... and she still has claws. Any other ideas?

      I have had a kitten for 5 years , very good natured , never hissed , nothing. Last night I stuubed my toe and yelled ouch and she ran up and attacked my arm, hissing and really clawed my arm. A few mins later she ran up from behind and attacked my other arm so bad her nail was stuck in my arm.

      Sounds like you really got her scared and she got defensive. if she is really aroused try to keep her in a dark room to calm down. Try to toss some treats to her while walking before she attacks to stop this behavior in its tracks.

      I took in a stray what looks like a maine coon five years ago. He was very aggressive at first, picking a lot on my boy cat but leaving my girl cat pretty much alone. As time went on he dropped the machismo and they all pretty much got along...UNTIL I brought home Mojo the Terrible. Our house has been chaos for two years with wild boy Mojo. My vet said he'd grow out of it. NOT! So recently the Maine Coin is going nutty and viciously attacking the mild mannered other boy cat again for no apparent reason. It is getting so bad that fur is flying and the MaineCoon is drawing blood! Help! If it's misplaced aggression what can I do about it? Thank you so much.

      I wished there was a solution for this, but often cats simply do not get along. I think management is your best friend, keep an eye on them while you are home and keep them separated when you are not, safety is your main concern. Redirected aggression does not usually last that long! sounds more like they are incompatible..

      Hi please help! Due to a recent move I had to kennel my cat. Its been about four months and I visit him at least once every one to two weeks. Every time I visit he is always happy to see me! The owner of the kennel (which is located on a ranch) have placed him in the barn house with his own cage and where she keeps her barn cats in their own cages as well. Well today I went to visit him. He was happy and meowing and happy that I let him out like I normally do to walk around a bit. He hissed a little at another cat in the room which he normally does and didn't think anything of it and started to organize his things in his cage and then I bent down and started to call out to him and then he just attacked me! He didn't bite just clawed at my feet and arm... I was wearing flip flops! He drew blood! I was actually scared of him. I don't think it was the shoes because prior to kenneling him he lived with me for over a year. He also lived with other cats, dogs, and children. But now Im ready to get a new place and going to take him home in a week. I had also noticed a decrease in play when I visit him. I was thinking of asking the owners to remove him from that area and put him back in the main boarding area ( again they only moved him out there because he had been there so long and to be around other cats). Do you think he will attack again? Im worried because I have two dogs to worry about also. One dog he had previously lived with and a new puppy. Thanks

      It is very hard to say if this will continue at home. I am afraid it may since there would perhaps be too many changes. Give it time, keep him in a small room the first days to adjust and then gradually allow him the whole house. Going from a kennel back to home is a big change and can be overwhelming after time, I would keep the dogs away for the first week or so, best of wishes.

      Hello! I need help. I recently adopted a kitten. He's probably around 8-10 weeks old and although originally hiding under the bed/dresser at every opportunity, it seemed as if he was slowly coming around. A week after I got him, he had a case of diarrhea and I've had to lock him in the bathroom for the last two days so he doesn't make a mess, but I'm extremely anxious to let him out again and try sit in there with him as much as I can. His vet appointment is tomorrow but, now he's become distant. Before, even when I first brought him home he would always purr and respond to me petting him. Now when I go try to play with him he shies away. Am I doing something wrong? What should I do differently?

My cat 2 year old tuxedo has shown heightened aggression towards me for the past three days. It usually just happens out of no where where he will start hissing/scratching/ and biting if he gets the chance. He has never been like this before except to our one cat sitting once when we were gone. Can the cat be pissed at me because I am home too much this week?

I've tried giving her treats, even seperating her from the kitten with her own food and water. Shes never been one for alot of affection.

      We have a 5 y/o m/neuterd cat who has been increasingly aggro since hitting sexual maturity. He grew up with 2 of the 4 cats he attacks, and we have since added 3 dogs to our family. Have had him tested - he is not ill (vet suspects brain issue). He gets focused and we have to physically interviene. Fur flies everywhere. No one is happy except him!

      He even attacks our dog that is sweet and submissive to him. This dog is 4x his size. We also have a 3.5lb chihuahua who s terrified of him that he attacks. We've tried playing, crating, re-intro.

      We have lived in three home with him, we have one.cat tree for every cat and 6 litter boxes.

      We feed preymodel raw, have since he was 1 1/2 (1 yr after aggro started).

      Some cats do not do well in multi-cat and multi-dog households. I think he is simply stressed and acting defensively. It could very likely be the addition of the dogs made him feel stressed and reactive. He may feel better in a homed where he is the only cat or with other cats he may better get along with. Do you have a family member or friend that could keep him for a while so to see if he is still acting the same?

He then proceeded to hiss at me so i picked him up and took him to his food dish, thinking he was hungry, he looked at it, hissed at me, then meowed some more. My sister came in and he got into a sitting position and stared at the wall, then he layed down and continuously cleaned himself. What is wrong with my cat?

      My area of specialty are dogs, but what I can say is that I really never met a really mean cat, most were acting out of fear or stress. You can try a Feliway plug-in which release pheromones which relieve stress, you should consult perhaps with a cat behaviorist or a vet who is very knowledgeable about cat behaviors. Some cats appear to not do well in homes where there is too much going on such as noises, kids moving fast, loud voices etc. Questions to ask are: What happens if you try to engage him in play? When exactly does he growl/hiss/attack? What seems to trigger his reactions? Again, for a serious discussion consult with a pro in cat behavior. Best wishes!

      I've got two cats that are brother and sister. They've come from the same litter and when they were young they were inseparable. However over time the male has become more and more aggressive to his sister. It mainly happens about an hour before feeding time.

      I've read that cats can get aggressive when they are hungry, so I assume its this and the easy solution is to feed them. However they're also both a bit overweight and I want to get them to a healthier size, so feeding them whenever he gets aggressive doesn't seem like a good solution. I also fear that when I feed him after he's aggressive that I'm rewarding bad behaviour.

      Any suggestions?

My arms are so scratched up, I look like I have been abused. Yelling, spraying with water & putting him in a separate room do not work;he enjoys water, and scratches flooring &doors if they are closed. I am going to have to resort to declawing or giving him away if this doesn't stop(neither of which I want to do.) My concern with declawing, besides the procedure itsself, that he also bites! Could he just be sick or is this a stage? He is around 2.

      My 3 yr old indoor cat is becoming more and more aggressive (hissing, biting, swatting)- it appears to be redirected aggression - he is always staring out the window at birds, squirrels, cats, raccoons etc. Anyone who enters our house that has any animal scent on them gets hissed at. My question is - if we let him go outdoors (he has claws and is neutered)-would that help him release his aggression? My feeling is that his anxiety with only seeing the world through a window is making him paranoid and that if he encountered other animals he may better deal with their scent on people.

      Please help me. I have two cats, one male, one female and 4 dogs. All are spayed or neutered. The male cat was rescued from a family when he was about 5 weeks old. They decided when he was 8 weeks to get rid of him, so I took him. He was a great little guy but decided that I was his property and stated humping my arm. I had him neutered when he was 6 months old per my vets recommendation. He doesn't hump me anymore but is becoming more and more aggressive - he zips through the house - beats up on the female cat, climbs up on top of my cabinets now, torments one of my huskies, which I am grateful that she only chases him and not tries to eat him. I am at wits end. He has been trying to get outside and has on a few occasions, but I manage to get him back inside. I now have to raise my shades or he pulls them down. I don't want to take him to a shelter as I know they will put him down. My groomer is kind enough to try to cut his nails as I am bloody from being his racetrack but that is one heck of a process. She even has to muzzle him and tape his feet. Help what can I do to calm him down, he is just about a year old now.

      Carla, you make an interesting observation. I really though cannot give a straight answer as to what would happen. It could be he is exhibiting ''barrier frustration'' being unable to chase as he would normally do if allowed outdoors, but outdoors, once able to ''hunt'' I am afraid once back indoors the frustration may further increase, exacerbating the problem. It may perhaps help to provide a more enriching indoor environment while blocking views to the outdoors if access to windows makes him so reactive. There are more and more interactive toys for cats on the market worth checking out. The outdoors can be a dangerous place for a cat to be, especially a cat who has lived most of its life indoors. Best wishes!

      Kathi, your cat may be stressed. Some cats have a hard time adjusting to homes with other pets. There are more and more cat behavior specialists and I think a consultation with one may be helpful, so they can observe your cat and assess the situation. It may be worth it to invest in one of those pheromone plug-ins such as Feliway. Best wishes!

      This may be premature, but I'm looking to smooth over a relationship between two of my cats that seems to be disrupted by the presence of a new cat. This new cat, about 6 months old, is a stray I took in and is currently confined to my downstairs bathroom. I know that my cats do not have the ability to understand that her presence is temporary (as I am in the process of finding someone to take her) but I am worried by one of my cat's behavior. Two of my three cats (male and female) are very good buddies and will play, groom, cuddle etc but now the male has become hostile towards the female, hissing and growling when she is near. He doesn't have a problem with me, which would make sense to me, but for some reason has redirected his anger/fear of this new cat at his buddy! I know she is a forgiver and will be fine when he gets over it, I'm just wondering if there's anything I can do so he isn't angry at her. It's just kind of strange to me that he is taking it out on her, almost treating her like he did when I first brought her home...just looking for some insight here. Thanks.

      Try re-directing his play mode to something else that is not your hands. Like say he is starting to get to revved up? Toss a ball across the room or dangle a string and play with him. You want to make clear that hands and feet are not toys. He is not supposed to be playing with your hands. If he grabs your hands, it is best to go limp instead of pulling back which will make him more excited and may cause more damage since he may tear more into skin if he is biting, best wishes!

      I have a 9 month old neutered kitten and he's always been very playful, but sometimes it can turn into aggression. He can be calm and, then the next second he will start attacking me. I thought at first that he could just be over stimulated and needs a release of energy, but when I try to play with him with his toys he just isn't as interested in it as he is with attacking me. Should I try new toys or something? And how can I get him to relax after he attacks?

      Try to redirect his prey drive with more interesting toys that move and stimulate him more. If he attacks you arm or hand, go limp, moving will only make him more excited. Re-direct his attention to toys. If he is too revved up, stop all attention and become extremely boring.

      Whatever is causing these attacks it sounds like defensive aggression triggered by stress. A pheromone plug-in diffuser may help at times. Some cats do not do well with changes if there were any recent ones. Also, it is always a good idea to rule out any medical conditions that can cause such outbursts.

      Hey,

      My mom has a kitten maybe a few months old, she was given to my mom after being found in an abandoned house, all alone. When they got her she was very small, like the palm of your hand, and has extra thumbs on her front claws. Anywho, she is very aggressive, clawing, biting, hissing, GROWLING! I have never heard a cat growl. She has always been like that, they took her to the vet and she had worms, and they said that might be causing the aggresstiveness, but after they treated them and she is still the same way. She acts like that to my mom, dad, brothers, any guest. everyone. You can not pet her, you can not even go near her. Since I have been here the past week or so Ive tried feeding her during the day to see if maybe shes just hungry, and give her water. still shes crazy. We tried treats, and she takes the treat then bites you. Its kind of upsetting to me because my mom and daughter love the cat but shes so mean I don't want my daughter going near her, because she scratches and bites. Do you think the extra thumbs bother her at all? I mean shes a house cat do you think declawing her would benefit her any??

      Adrienne Janet Farricelli 5 years ago from USA

      Having extra thumbs, your cat is ''polydactyl'', I do not think this may be linked to the aggression unless there are nails growing into the paw pads causing pain. Can you check for this or have a vet check his nails and pads? This can be very painful and cause stressful behaviors. If she checks out fine, the behavior can be stress related, any recent changes, new baby, new pet, new home? I would try some pheromones ''feliway'' and see if they have a calming effect. I would also have her undergo a thorough veterinary exam to rule out anything medical. At this age, a cat should be happy and playful, unless she underwent some horrible trauma or she is genetically prone to be this way. Was she this way when you first got her?

      Our cat is very aggressive and seems to be challenging us all the time. She has been neutered which we thought would calm her down but it hasn't. She seeks attention constantly but we don't like giving it to her as she bites and scratches us. She doesn't respond to being told off, and we also have problems with her climbing on all the furniture and surfaces. Is she just bored? We have to lock her out when we have a child over as she might attack them.

      Cats need a like of environmental stimuli ie cat trees and other toys that make them feel stimulated mimicking prey. Most cats in household are bored. Look for some interactive toys for cats. Feliway plug in may help if she is stressed. If she bites when you pet her, try to get up suddenly and leave. Petting should be on your terms not hers.

      Thank you do much I will definitly get up with my mom to find some feliway plug ins, she wont really let you come near her to cuddle with her. She does have a scratching post, and my mom wants to get her one of the cat hotels where she can climb and sit in the cubbies. The other night we did find her to calm for a few mins she smelled my hand and then rubbed her head on my hand and let me pet her, and my mom and daughter she let them pet her today but it was for a couple mins. But she looked like she enjoyed the attention of them petting her. I will definitly look for the Feliway plug ins. Thanks for your help, and I will definitly keep in touch and let you know how shes turning out :)

      Hey so we didn't get the feliway, but we did try a treat like chew for her. Its called PetNaturals, and its for "calming" as soon as we got it I gave her one, and my mom says she seemed loopy or doped up but I didn't see that at all. She seemed to me to be calm and she even became cuddley. Although she is only about 5 pounds or so the little chew is for 15 pounds...so we decided to only give it to her every other day and about 1/2 of one, just in case she was dopey lol. So yesterday my mom gave her half of one, and she was so cuddley she rubs her face on you feet and legs and she will walk into your lap, and shes like a completely different cat! She occationally puts her claws out but not like everytime, and I haven't heard her growl like she was before! I am so happy I found this page and you gave me some advice because we would have never thought she was stressed out. :) Thank you so much!

      We have two cats, brother and sister (spayed and neutered). We have had them since they were kittens, they are now three.

      They are house cats but the other day the boy cat somehow got looked out over night. In the morning we found him waiting by the front door. :-)

      This happened two days ago, ever since the female cat has become VERY aggressive to him, hissing growing none stop . Why?

      He may smell different. When many cats were hospitalized at our vets office upon coming home they were often greeted by unfriendly family members. It helps if both go out together or rubbing him with a blanket that smells like home again. Expect this to happen again if he goes out again.

      That it is odd, especially if she got along with your dogs for all this time. I would have your cat checked by a vet just to rule out anything medical. Were your dogs away for some time? like boarded, at the vet? could your dogs have hurt her ie stepped on her tail? A plug-in diffuser such as Feliway may help.

      Hi, my cat is now about a year old. When she was a kitten I socialized her often...bringing her to my parents and taking her other places...she grew up around dogs...she was very playful and friendly...but once I moved into my own apartment when she about 6 months old, we visited my parents less and less....she hates going to the vet now.. She has no problem going into her cage..going in the car...but once we're at the vets or anywhere else besides home she growls and hisses and lashes out. She almost bit the vet. It really upsets me when she is aggressive with me because I raised her from a baby and she is super spoiled. Anytime she is outside of our apartment in an unfamiliar area if I pick her up or pet her she turns around hisses and tries to bite...however once we walk right back in the apt shes completely fine. I just don't understand...I've been trying to get her used to new and strange places...cuz I feel like she only feels safe at home...and getting another pet is out of the question...( my friend stayed with me do a short period and brought her chihuahua and my cat was mean for weeks until a cpl weeks after she had left.) she is spayed and an only pet. Is this something she will grow out of? Or is there something else I can do?

      Many cats are unfortunately this way and I have found that this is fear based. Because she is fearful she becomes very aroused and reactive to anything because she is in flight or fight mode. I am afraid it will take a great effort to change her as this behavior is reinforced since in her mind her lashing and growling has protected her in her mind. You can try taking her out on a frequent basis but without going to the vet. Make the outdoor visits brief and frequent. A feliway collar may be helpful for the first outings.If she gets better, take her on a leash to venture in the grass. However, many cats feel safe only home and this is hard to change. Best wishes!

      My cat seems to be more aggressive lately. I don't know if it's because I went on vacation a couple of times this month or it's redirected aggression from staring out the window A LOT. I got home today from a 2 and 1/2 day vacation. She's attacked me 3 times. In fact, while I was reading this article's comments she chirped, walked over to me, rubbed her head on my phone and then tried to attack my arm. I didn't touch her and I stayed very still while she was standing on my lap. One time I woke up to her licking my face and without even moving or saying anything she bit my nose. She tends to pace the halls and make this weird meowing sound. The vet didn't offer any useful ideas. We play and I give her treats. Don't know what to do. Maybe the Feliway?

      It may be triggered from you being away. Many cats attack other cats when one cat is taken to the vet and returns home. So I can see this happening to humans as well. You can try Feliway or a calming product known as "composure". It may eventually go away once you smell normal again and go back to your routine. Some cats get easily stressed by changes.

      Please Help!! I have two cats, spay and neutered. My male has sent me to the hospital twice for severe bites. Most of the time he is a loving cat, but seems like at the beginning of spring every year, he acts like jekyll and hyde.

      History- Picked up Lucy as a stray almost nine years ago, 7 weeks later went to SPCA and picked out the only cat that appeared her age and looked like a Desi. These two became our children. At the time we lived on the 8th floor, high-rise. We use to let them in the hallway and they thought that was such a thrill, They both had their annual vet visits/shots, etc, even though they were indoor. I always had cats and dogs growing up and we never went to the vet, that was for rich people, but I digress...I wanted my cats to experience nature and go outside. We found a nice four level with a deck as well a screened in porch. They only are out when I am out with them. One day another cat came around and I tried to contain my cat and get him back to the deck, when he took a four-tooth bite out of my leg at the crease, behind my knee. That was it...I stood perfectly still and he proceeded home. Last year my son moved back home and Desi appeared to be on his best behavior since he was afraid of my son, became clingy to me. My son moved out two months ago and the past three weeks have been hell to pay. I was getting into bed and Lucy above my head on her own pillow, Desi was lying on the other side of the bed when he awoke and attacked me in the fact. This really disturbed me, since he always sleeps on my legs and the night of the eclipse moon he walked up and down the bed between me and the window, sort of protecting me. Again, I digress to the situation - I wanted to let him have another chance and left the bedroom door open one night, in the AM he was in his usual spot but when I tried to get up he began to growl at me. Hasn't been in the room since.

      Three weeks ago there were two raccoon's on the deck and he saw them and went wild. Attacked my Lucy and started his growling and hissing at me. it began to taper off but two weeks ago a cat came on the deck and after 15 minutes of territorial growling, stupid me let him out...two hours later I found him on the neighbors deck and carried him in...The following weekend we took him for his senior exam and explained our dilemma. He immediately growled at me upon entering our house and since then it's been a battle. I had these two so well trained that I could take them on the deck in the morning, have my coffee, then they would come in and I would feed them and get dressed and go to work. Let me mention that he has not wanted to do this routine since my son has left. I realize I am all over the place but this situation has got me stressed. The Vet put him on Reconcile with pill pockets, but after three days of that he stopped eating...on the 6th day I stopped the meds. The Vet want him back in, but I cannot get near him. Yesterday I let him out figuring that would be the cure, only he would not come back in and we had a battle, because I refuse to leave him out all night as there are fox and coyote out there. Lately I have to get the significant other to go grab him and ring him in, which is also a hassle. I am so upset and may have to have him put down as I cannot move about freely in my house and have to block out rooms, all of which I need access to...this cat just hates me and I do not know what else to do :/

      I don't really think this cat hates you but is rather highly stressed. Did you try Feliway already? If sights of raccoon and other wild life arouse him he may be suffering from re-directed aggression, in this case, access to windows and the outdoors should be blocked. Try to consult with a certified applied animal behaviorist and see what your options are, best wishes.

      Just adopted a new cat from the shelter, she is 4 years old and spayed. The first few days, she was entirely loving and sweet. I have another cat, 2 year old blind, neutered male. They only met briefly once, and the new one got scared and attacked. Since then, the little female has been a bit more aggressive. I am reluctant to return her to the shelter, out of fear that she will be put down due to the reasoning behind the return.

      Just recently, I was petting her and she was all calm and sweet like she was originally, then all of a sudden, she went crazy and attacked.

      Give her a bit of time and try your best to provide quiet surroundings (no guests, loud kids, and possibly keep the two cats separated until they get used to each other's smells and presence from another. A feliway plug-in may prove helpful in such a case. It is hard to say if this is a permanent problem (related to her genes, some cats can be weak-nerved by nature)or if this is a just a transient problem related to being in a new place. Only time will tell.

      Starr, it's called classical conditioning, it's scientifically based and it is untrue that it will reward aggression, this is a myth hard to debunk! My school of thought is from personal experience after training several dogs and cats this way. I will not start a lecture on this because it is not the easiest thing to understand unless you have a degree in behavior science. Read Dr Sophia Yin under section F in her article below and also read Ian Dunbar's take on classical conditioning, great reads!

      We saved a 1 month old male cat from being killed. He is now a year and a half and is really very sweet cans he really loves oh two older cat (both female . ) of course the feeling is not always mutual but they'll tolerate his licking their heads. Problem is that when they try to move around the house he'll pounce on them and will really get them pinned to the ground. He's 15 lbs and is 2x their size. He's still sleeping in a separate room since there would be no way to sleep otherwise. As soon as one heads to the litter box he's all over them. And now he doesn't sleep through the night and starts pounding on his door at 3am. Just not sure what else to do to get done peace. I know he's just playing but I'm afraid one if the older cats is really going to get hurt. We introduced them very slowly for the first few months. Especially since he was so tiny. Did I wait too long to integrate them? I love them all but need some sleep!

      Try to keep lots of interactive toys or access to windows available so they stay awake during most of the day. Cats are nocturnal by nature and you can prevent your cats from being too hyper at night by keeping them occupied during the day. one of my cats got into the habit of howling in the night and we now close him for the night in the bathroom and he now settles down because he knows the routine: time for bed!

He's humping blankets, anyone who sleeps on the futon ( including company) and my CHILD in his BED.. after he tries humping my child, he goes up to his neck and lays down like he's "subduing" him..he's always acting like he's scared ( the cat )I don't have the money right NOW to fix him, ( mind you I AM ) but what can I do in the meantime?

      Hi,

      3 months ago I brought home a new female kitten. I already have a female cat who is around 6 years. When she was younger we had another cat, so i presumed she would eventually get used to a new one. However, she's still growling and hissing at it and us and we can barely ever pick her up anymore. I've been using a spray version of feliway, and sometimes it appears to work but not the majority of the time. The poor girl is very stressed out and I think she may be losing weight. I don't believe it's a medical issue since it only started when we got the new addition. And my cat gets REALLY stressed from the vets, so I want to try and calm her first. The kitten doesn't help matters since she's always chasing the elder around the house and trying to jump on her. We've tried to stop her from doing that but she wont cut it out. Is there anything else I can do? (We try and give the elder tons of attention but half the time she wont let us near her). Thanks for any help!

      Sometimes certain combination do not work out. Usually, older cats growl and hiss to younger cats as a form of discipline but it generally stops at that. Since this kitten is persistent and still follows her despite her requests to be left alone, I see this as a problems, especially if you had the new kitten for more than a week and there is no improvement. Your older cat should have a place to go where she can be left alone. But her stress levels are quite high, so I really think this is not a good combination personality-wise. Normally, a kitten should back off... and normally an older cat should not be so stressed out by a kitten as to become aggressive towards you.

      It takes some time for the hormone to stop production- I would think about 3 weeks- but neutering will not solve behavior problems that are not associated with hormones. Marking reduces because it is hormonal-the cat does it to keep other male cats away- but aggression and whining may not stop unless they were due to females in heat nearby..

      If your cat was acting normal before, I would suggest excluding something medical, cats can get grumpy when they are not feeling well and they do not always show pain, because pain is a sign of weakness. It could also be something happened like your dogs smell different or something stressful is going on. Try some Feliway.

      Get a pheromone plug-in such as Feliway. Sounds like this other kitten was perceived as an intruder and disrupted your cat's routine and perception of safety. If her aggression started just the day this new kitten was brought in your home, I doubt you mother cat is distancing your kittens, as your vet suggests. It sounds more like re-directed aggression and stress. Try the plug-in. It may also help to pass a towel on the mother cat and then rub the same towel on the kittens so they smell like her and she feels like every thing is back to normal, best wishes!

      My cat and I just recently moved to a new state; NY to TX. She grew up with an older cat that was left behind with the ex and now spends most of her time alone in a room about the size of my old apartment. Her behavior towards me hasn't changed at all. She's still the loving playful sweetheart she always was. But towards my parents, who are admittedly new to her, she turns aggressive, but only as they are leaving the room in which she stays. She greets them lovingly, and plays nicely with them but as they try to leave she will block their way, hiss, claw and try to bite their ankles. She was never this way in NY with our visitors. She's always been a very social cat sitting on people's laps and purring and vying for affection. Is this loneliness now that she spends most of her time alone? Or is this stress from all the changes that have occurred this past month?

      Moving to a new place is stressful to many cats and takes a period of adjustment. Try using a feliway plug-in. Try to provide lots of enrichment in the room she is left alone for the day, ie cat trees, safe toys.

      I adopted a female cat when she was 6 months old. I was told she was abandoned. She is a very loving cat. She has typical cat behaviour like getting aggressive when over-petting, etc. This past January, I tripped and fell and made a loud noise and she all of the sudden attacked me and started growling. This went on for several days. I took her to the Vet and she was fine physically. I was told not to look her in the eyes and give her time to re-gain my trust as I must have scared her when I fell. I had to keep her isolated and away from me for awhile. She seemed to get over the event after a week or so. Today, I was in the other room and inadvertently left the blinds open and she got her paws wrapped in the blind cord. When I heard her crying, I immediately ran into the other room and rescued her from the cords. She scratched and bit me as I did this. Then, when I walked away, she growled and hissed at me and attacked me. She drew blood. She was like this for several minutes. I finally shut the door to my room and ignored her. After an hour or so, she seemed ok. But, she is still a little leary of me. Do you think she was just scared? Or, will I be going through the event that happened in January all over again?

      I had a cat that acted the same way. She used to attack my feet, hiss and growl after my hubby fell on her and then she kept on doing it. Vet said she was healthy and had no clue on how to help her. I used Feliway plug-ins which made things better but she kept on doing it. It also seemed as the carpet was making her nervous as she used to get little shocks on it when she ran. I gave her to my parents which have only tiles and occasionally she still attacks when they wear new shoes or almost step over her. It may help to perhaps drop high-value treats as you walk by. It s my belief that most cat aggression is fear/stressed based.

      Cats are highly sensitive creatures and when they aggress it is often caused by stress. The highly pitched voice may be stressing her and causing defensive aggression. If this happens only in this circumstance, stress could be the culprit.You can try a Feliway plug-in or have a cat behavior specialist take a look. You can try counter-conditioning and desensitization by keeping your child behind the door, scream at a low volume at first while you feed your cat treats if she is able to take them . I have seen horrible injuries from cat bites, so this warrants attention.

      Hmm... often this behavior is seen when one dog is taken to the vet, let outside and assumes a new smell that makes the other cat nervous. At other times, it could be re-directed aggression. say your cat sees an animal out the window, she may redirect her frustration on him. You can try a Feliway plug in to calm her down or you can try feeding her some high-value treats every time she sees him from a distance so she starts associating him with good things. this is called counterconditioning/ give it a try, best wishes!

      I have 3 cats. 2 males and a female. My boyfriend and i recently moved in together in August. I had 1 male, Oreo, and 1 female, Delilah. He had 1 male named Boots. It only took no more than a week for Delilah and Boots to get use to eachother. Oreo and Boots took about 2 weeks. Starting earlier in November Boots has become increasingly aggressive only towards Oreo. Oreo is a very timid cat, although large, he's a huge chicken. Boots will attack him while Oreo is using the litter box, sleeping or just trying to walk by. At night i've started to lock Boots out of the room just because i can't sleep with Boots constantly growling and hissing at Oreo. There are no cats outside that he's seen which would cause redirected aggression. He never does this towards Delilah. Both males are neutered and have been a long time. Boots' behavior seems to only get worse and worse, does anyone know what's going on?

      Adrienne Janet Farricelli 4 years ago from USA

      Just as in dogs, some cats may just not get along. The chances of not getting along are higher among male cats. Boots may have figured out how powerful he is and that Oreo is scared of him. His attacking is reinforced if Oreo leaves the area or runs away. This needs to stop. You can place a collar and bell on Boots, so Oreo can be warned when Boots is coming close. You can try to rub both cats with a common towel multiple times daily to transfer scent to each other. And you can set some supervised periods and reward non-aggressive behavior. So say you have Oreo walking by and Boots n your lap is not acting aggressive in anyway...then praise him and then slip him a small treat into his mouth. However, you may need to re-home a cat if things don't get better, it's not right for poor Oreo to live in fear. Best wishes!.

      Hi, I have a young cat (2yrs) who is a very lovely but playful little thing. She's not normally aggressive but will be a little feisty when she's had enough of your company. My problem is that she is extremely aggressive when we take her to the vets,so much so that they are unable to examine her. I know it's through fear of the new surrounding and smell, but she is a curious/hunter cat and as a result has had a cpl of scrapes where we needed her checked over. Is there any way we can try keep her calm enough for an exam? I keep her outside the surgery until its time to go in, and speak to her quietly while we we wait, but as soon as we get in there she goes wild. The agression disappears as soon as we get home, but im worried as she's not well this week but the vet can't get near enough to find out what's wrong :-(

      We saw many nervous kitties at the vet, and with cats things get a bit tricky as these animals don't like at all leaving the safety of their homes. Add on top of that a car ride and then going to place where they get shots and stuff stuck up their bum, and you have the perfect recipe for one not-so- happy camper. Cats used to bite our staff much more than dogs, but we know well it's all about fear. There are some calming products for cats now, not sure how well they would work, such as Feliway and Composure cat treats by Vetriscience, Also, google "thundershirt for cats".

      Sounds like a case of re-directed aggression if these episodes happen when the cat sees something out of the window and then attacks your other cat.

      Hi,

      We have a 10m/o kitty. I recently moved my cats scratching post from our living room to our bedroom, to give our cat a high up place to sit and look out the window, instead of knocking all of our books off the shelf.

      The instant we did this, she freaked, refused to come and eat and go to her litter (which were right next to the scratching post). I tried to show her that it was a positive thing but the instant she sees it she freaks out and runs away and hides. She would barely play with it while it was in the living room other than sleeping on it from time to time when we were in there.

      This morning I tried to close the door to the room when we put her in there so she could see it was just her scratching post......was the the worst idea ever, she started jumping off the walls and ran into the closet and just started crying. We then decided to put the scratching post back to it's original spot.

      Problem is , is that even though she saw us take it out, she still refuses to come back to our bedroom to eat and use her litter. She just isn't eating or going at all. It has only been a day but Im still worried we may have traumatized her in some way. Did I mess up my cat? How can I help her be okay again? Thanks for any help you can give!

      Sometimes cats are very sensitive to changes. It could be your cat was used to seeing the post as a stationary object and now that she saw you move it, it terrorized her as she perhaps saw it as a sort of big monster so now she won't go anywhere near it in fear it will "move"again. You can try to use a Feliway plug diffuser or spray or give her some time to realize that the post won't harm her in any way. The fact you closed her in the bedroom with the scary monster didn't help. This in behavior terms is called "flooding" while what you want to do is desensitization and counterconditioning. You can find explanations of these processes in my hubs on dog behavior modification. --it applies to cats as well--You didn't mess up your cat, cats recover from this, but they just need time and gradual exposure. Your kitty won't eat or use the litter box in this case because she's not comfortable and fear interferes with eating and eliminating. It may be a good idea to place her litter box in a place she goes to feel safe for now, and scatter food nearby the areas she fears the most so she learns to associate these places with good things again. Best wishes!

      Thanks for stopping by Gail641, tolerating is much better than being miserable. We had a miserable case once where a Siamese cat refused to eat for days on end after a new cat was introduced to the household. The new cat had to be re-homed as the resident cat lost several pounds and they couldn't entice her to eat!

      I have a 2 year old female black cat. She got fixed in the first week of April. She was peeing on everything. The vet said she had a bladder infection and fixed her and gave her a shot and she quit peeing. Since then she has gained at least 3 pound and tripled in size. She was a small cat before she got fixed. Her eyes are dilated all the time. One moment I am holding her and loving on her and she is purring then she jumps up hiss's at me and tries to bite and scratch me. She used to be a very loving and affectionate cat. Yesterday we brought in a stray 5 week old kitten and she tried to kill it. She had started attacking our dachshund before we got the kitten. She used to be so close to him that they would cuddle on the couch and play all the time. I don't know what is wrong with her. Any help you can give would be greatly appreciated.

      Most aggressive cat behavior is caused by stress, fear or pain. It would be best to have her see the vet again to rule anything physical going on. Dilated eyes can be caused by fear but also hypertension. If the cat is by the sun or near a bright light, do the pupils get smaller? they normally should. If she has vision problems, stress and anxiety may develop and make her more reactive.

      Hi. The facts: I have a 2yr old DLH (I shave her when it's too hot), spayed, female. It's just me and her for the most part. My boyfriend comes over every other day or so (for the past 6 months). She doesn't really seek out attention and is not really a lap cat. I have no other pets, but worked in an animal hospital when I was home (in the US) and I've since moved to Egypt, where sometimes I volunteer at the animal hospital. She isn't always crazy about the smells from work (she's never attacked me because of this), but deals with it. My boyfriend wants her to be more of a lap cat so when he holds her, he doesn't let her go until she's calm, but he scratches her chin, which she loves, and a few minutes later is completely asleep! She did fall off of the balcony 12 days ago (from 4 floors) but had no injuries other than shock.

      Anyway, I brought her to bed last night as usual. I got up this morning and she usually follows me into the bathroom. She didn't this morning and when I finally found her, she peeked out from behind the bed in the spare bedroom, then attacked me and scratched my legs. I was able to scuff her after using treats, put a sheet around her hoping to calm her down. (I thought maybe something spooked her over night). Then I let her go and she was hissing, growling and spitting at me...I didn't approach her because I could tell she would attack (again, she's never acted like this before unless I take her to the vet and even then her aggression is not towards me). Even just a little movement (crossing my legs), even though she was 5-6 feet away and she would start growling. So, I called my vet in the States and she said try to put her in a room, with food, H2O and a box of course, and leave her alone for the day or two and see how she does.

      I've been reading about redirected aggression, territorial aggression, medical conditions etc., but could something like this make her change over 10 hours? Is it possible something has been building up and she just lost it? E/D is normal, and no V/D either, so I'm at a loss. Any ideas?

      I have 3 cats who have lived together for 8 years. Normally, they all get along really well. In particular, two of them, Sammi and Hershey would play together every morning. But now Sammi seems to think Hershey smells funny (nose in the air, smelling around, leading to him) and when she gets close to him, she'll growl, hiss, then when he runs she'll chase and attack him. The third cat Idgy joins in on the attack but seems less bothered by him otherwise. I've inspected Hershey and he doesn't have any cuts, lacerations or abcesses. Everyone is using the litterbox appropriately. He'll just be sitting watching out the window and it's like she hunts him down. Now he's very scared of her. However, all 3 have been laying on the bed with me at night, just in their own litte zones. And this morning when Hershey made a move to change locations on the bed, Sammi gave him the evil eye and meowed so he backed up and that was that. A little later, though, he successfully moved into that new spot.

      Since you mention they lived together for 8 years, that would make them older than 8 correct? I would mention this behavior to the vet for your cat's next physical--.which should be twice a year in senior cats. At times, reduced senses can be a cause of unusual aggressive behavior. So reduced hearing, or reduced vision at times may cause peculiar behaviors. At the same time, there are stories of cats detecting illness in other cats and reacting aggressively-when the owners couldn't detect anything, until the cat in question was assessed by a vet. Some cats may attack other cats as they become weaker. Just throwing out some possibilities. Did you try a pheromone diffuser such as Feliway?

      A physical exam to make sure the attacking cat is not ill, calming aids such as Feliway, management to prevent rehearsal of behavior and then if nothing medical was found in the cat, behavior modification which is best done along with a professional.

      Hi there,

      I have three cats (2 boys and a girl) and one of my boys, Shia has been acting out toward my other male cat ( Rafa) for the past few months. I've had Shia since he was 12 weeks old and I got Rafa when he was 10 months; both of them are now 4 years old. Up until recently Shia didn't have a problem with Rafa, they got along great.

      But now whenever Shia sees Rafa, he immediately starts hissing and growling, and then sometimes lunges at Rafa if they are near each other. Shia doesn't have a problem with my female cat at all, only Rafa.

      I have no idea what to do. If you can give me any tips or ideas on how to calm Shia down, that would be so amazing!

      Thank you!

      Anytime there's a sudden change in behavior, it's important to see if there have been any recent changes. Did Rafa recently see the vet? was he ever taken out? any health changes? a vet visit at times reveals something that we cannot comprehend. you can try getting a towel and rubbing Shia with it and then rub Rafa with it so he get's any unfamiliar smell off and gets a familiar smell. You can try Feliway plug-ins. Is Shia seeing stimuli out of the window and could it be he's re-directing? try to remove access to windows if he gets too stimulated. Another option, try feeding treats to Shia at a distance every time he sees Rafa, when Rafa is out of sight no more treats. Best option: consult with a feline behavior specialist.

      My 13 week old kitten is just terrible sometimes. We adopted him/her off the streets when it was only a week old (mother had abandoned it.) Lately it's been exhibiting very wild behavior, running at full speed up and down the halls, climbing and scratching, and most of all biting. Everything has been exactly the same since we adopted it so I don't think it's scared. Maybe rough playing? If so would you be able to tell me at what age he/she will grow out of it? (Still don't know the gender sorry)

      Hello - Last night my cat that I have had for over 3 years must have gotten caught in a pastic shopping bag and drug it across the house and I think she got really spooked. I am her favoriate person - she never hisses at me, she sits on me all the time and now she is being really aggressive. I think she might even think it was her brother that scared her because he was right behind her and she now is hissing and growling at him constantly. Her pupils are dialted a lot and her fur is standing up a lot. She is acting really paranoid.

      I don't know what to do or if this stop because this just happened last night, but I am worried because she is my baby and now I am scared to pet her because she freaks out. She was sitting on me earlier sucking on a blanket and was a little better, but not anymore.

      I have two 5 year old male pure bred Himalayans from the same litter. They are both neutered and were adopted together by us at 12 weeks old. We have no other pets, and my two have never been outside except in a crate for vet trips. They have always gotten along well, and enjoyed chasing each other, rolling around (non-aggressive wrestling), grooming each other, etc. For the past week and a half, the more outgoing of the two has been yowling in short bursts, racing around the house like he's being chased, jumping up the walls like he's trying to do a skate board trick, and has chased/caught/wrestled his brother to the ground and bitten him, all very aggressively. When these incidents have occurred, the more passive cat has screamed and yowled until we separate them. Neither cat has ever hissed or bitten me, my spouse, or my 2 kids who were 5 and 8 (now 10 and 13) when we brought the cats home. None of it happens every day, but over say 11 days, it has happened maybe 5 times, always in the evening/night hours. Any ideas? It is concerning to say the least, and scary for the kids when they see it happen.

      Cats don't like changes,and it's evident that your other cat doesn't like the new hairdo, sure your cat is always the same, but from your other cat's perspective he looks different and even smells different since he was at the groomer. You can try Feliway, or feeding your cat tid bits of high value food every time the other cat is around.

      Hello. I have my cat for a year now, since he was born and is a male. We haven't gotten him fixed yet and before he use to play kindly until we moved to a new house. Recently he claimed the staircase as his area and whenever we walk up and down the stairs he would pounce at our feet, but now something worse happened. My father had a friend over with a little girl and she peaked her head to the staircase and he just jumped and attacked her whole head that she had to get stitches. My dad is very insecure about him now and thinks my cat will just randomly attack any of the family member at anytime. Oh and recently he was introduced to catnip to try to calm him down. I don't know if it could be his hormones or just trying be dominant. My dad is refusing to get him checked out by a vet because of money issues and maybe give him away :(

      Any way you can put a baby gate or block off the area so he can no longer have access to the staircase? If it's only that area that triggers such behavior, the solution may be as easy as that. Did your previous home have a stairway? If not, it could be he is frightened by it and when you walk there it may seem odd to him seeing you so high and then he may feel threatened by how you move your legs in an odd fashion as you climb up and down.

      I have had my female cat for about 8 months, and she is 9 months old. She has lived with my boyfriend and I the entire time and has had normal cat behavior. Recently my 3 kids came to stay the weekend for the first time since have had the cat. The entire time they were here she was very aggressive. She would hiss and growl and swat at them. She even started being aggressive towards my boyfriend and I, which is very out of the norm for her. The children left her alone, and she still seemed to be very aggressive towards all of us. They left a few days ago and she hasn't returned to her normal self. She is still aggressive and seems to be angry. I really don't want to get rid of her, but we can't even touch her.

      When animals are stressed those stress hormones linger for some time. Let her stay quiet, try Feliway and limit her exposure to stress events. If interacting with you and your boyfriend further causes stress let her stay alone in a quiet room with food/water until she feels safe to come out.Also, consider having her see the vet if there are chances she may have gotten hurt somehow around the kids.

      Hello, almost a year ago my husband and In took in a beautiful rescue cat. Unbeknownst to us, she was pregnant, and after little over a month gave birth to 3 of the most spoiled, loving kittens anyone could ask for. We kept them all, and I love each and every one of them, and they are all so unique. Well, one of the two female kittens, Lazy Bones, or LB for short, is generally the calmest, most docile of the three kittens, out of nowhere scratched my 15 month old on the nose today. Yesterday scratches appeared all up and down my daughter's legs. She did not cry, and there were a couple of them in the room, so I couldn't be sure which one did it, but LB was present during that time as well, so now I'm pretty positive of the culprit. LB is 8 months old now, and aside from the two scratching episodes, she has not displayed any other signs of aggression, and my daughter doesn't appear to be scared of her, not even a little bit. What could be the cause of this scratching? I know my little girl wasn't being rough with her, she wasn't playing with her at all. I love this little kitten, and I don't want to give her up, especially if this is a temporary, fixable thing. Please help! I'm desperate for both my daughter, and LB.

      It's hard to say without seeing the behavior, the context and the accompanying body language. Since you suspect this particular cat, I would suggest not to leave cat and toddler alone; the cat can even scratch an eye! It could be a case of redirected aggression, from getting aroused, stress of even a medical condition. A vet visit may be a good place to start, and afterward, you may want to consult with a behavior professional such as a Certified Applied Animal Behaviorist or veterinary behaviorist.

      This sounds like a mystery, yet, there has to be a trigger. Since it's affecting both cats, most likely there something that's stressing them out. Even if you do not notice anything, think if you ever left them alone in the house or didn't watch them, can it it be something scary happened in your absence? Since your cat attacked you while you were sleeping, perhaps something scary happened just seconds before? Could there be static in the carpet, upholstery? Any animals they may see from windows? Any stressful events like loud noises, planes flying low? Any air blowing from a fan or somewhere else? Could it be your female attacked you in your sleep and was reacting from your male perhaps jumping up as he did on the couch after licking? Does the skin on their backs ever moved as if itchy and they get irritated from it? Even though they saw the vet regularly, things may change suddenly, so doesn't hurt to give them the benefit of doubt that something medical may be going on, especially if you tell your vet about these behavior changes, he may do a visit more targeted towards medical causes for aggression. It could be one cat has a problem and the other is stressed out from it and is reacting too. What area of his body was the male cat licking seconds before he jumped up? Observe them very carefully, but please be very careful I am so sorry to hear you got hurt so badly!

      They saw the vet only 2 wks prior to the attacks (worming tablets n check up) and were given a clean bill of health aswell. at the time my female attacked the male was asleep in my bedroom and did not wake or notice any problem until i got dressed to go to hospital. (i was asleep on the couch) and when my male attacked, the female was locked up because of her attack. (Attacks were almost a wk apart) he was cleaning his Head and i checked him after for any fleas cuts bumps anything and nothing i could find. Both attacks happened while it was quiet and fans, tv lights everything were turned off. We have tiles all thru the house no carpet and leather or wood funiture. and both cats are still fine with eachother they are still playing, eating and sleeping together they have never shown any problems towards eachother. They do not show me any issues they still want cuddles and follow me around and are very loving happy cats. Its only been these 2 night where they have done this (from my view) out of the blue. I have been observing them and they are acting normal like nothing has happened

      Sounds really a mystery! Since in one attack you were sleeping, I wonder if you were perhaps twitching or snoring and your cat aggressed because felt it was odd? Do you suffer from any sleep disorders like sleep apnea? When you were knitting, can it be your cat wasn't attacking you intently but was behind the couch after a ball of yarn? can it be you were about to fall asleep? or can it be he woke up from a bad dream? did any of his behaviors match signs of feline-hyperesthesia?I hope these were isolated events and that whatever triggered these attacks in those 2 nights is gone.

      Adrienne Janet Farricelli 21 months ago from USA

      The good thing is that they're all very young. They'll need to learn to communicate with each other. The hyper kitty will need to learn when the younger kitties had enough,and the calmer kitties will need to learn effective ways to tell the hyper kitty they had enough. All this should be done without through body language and vocalizations without hurting each other. It takes time for new kitties to adjust to each other and being in a new home. The ones that seem calm, may just be a bit stressed and may open up as they get used to their new homes. I really never saw totally calm kitties. As with dogs, they may through the honeymoon period, where they are a bit shy and reserved, then once they're comfortable they'll start engaging in play. It hard though,to predict how things may turn out in the long run. Your older hyper kitten may have missed out learning how to communicate if she was a singleton or didn't grow up with other kitties, but hopefully being young she can catch up and they can all learn from each other :)

      My male cat is 5 yrs old and a house cat. Hes been neutered 4 yrs ago. He has to be the sopiest calm cat going but just recently he's attacked a couple of friends of mine that have been visiting for wks at a time. He is all over them rubbing up against them n then he hisses n attacks them. They don't have pets. When I've stepped in he's gone to attack me and very badly. He makes this weird noise at the same time. I've been in tears cause this isn't my cat at all and don't like him being like this. Hes a very big cat and can jump higher than my head which I've had to protect with a pillow before when he's attacked. Can anyone help in regards to what I can do to get my loving placid cat back to normal? ?

      I rescued a feral female cat - she is extremely sweet and craves attention. However, if I pick her up below the front paws (with her facing me and lower part of her body dangling), she would lash out to scratch me in the face - very aggressive. Does she feel threatened?

      Could be she feels pain there (doesn't hurt to check with the vet if she was OK with that before), or doesn't like to be picked up. Most likely the latter if she was feral and never got used to being picked up. Look up some videos on youtube on how to pick up a cat, so that legs aren't dangling, also would not keep near the face for safety...but prior to that maybe get cat used to it gradually, giving tasty tidbits of food every time you touch her, then move up to pick her up for a second feed treat, then put down, then pick up more etc. Be very careful though you can get really hurt if she aims for the face! Maybe place some SOFTPAWS on her nails to prevent getting scratched.

      My dog and cat have always gotten along she use to sleep with him and rub against him until 3 days ago. We had a rat in the house and the dog went nuts trying to catch it while he was chasing it she ran after him and attacked him to the point that she made him bleed. She has had a litter of kittens 3 months ago but even after that showed no signs of aggression toward the dog she would even leave the kittens to lay with him. I can't get her to stop and don't know what to do!

      Hi there, it's amazing that you still answer comments after all this time, thank you! Quick question. I have 2 Siberian cats, brothers, grew up together, very good natured. One is super agile and jumps great heights, the other not as brave. I've stopped letting them both out on the balcony because the agile one jumps straight for the railing and gives me a heart attack each time he pretends to be walking a tight rope (9th floor). However, the other day, I let the other cat out for a while, the agile cat was sleeping and didn't notice.

      If I keep letting one cat out and not the other, will the one that stays in get jealous, especially if he sees us hanging out on the balcony?

      I don't think cats would feel "jealousy" that way, perhaps may just want to join the other cat.

      A lovely cat Catalina moved into our home as we have a hole under our house.. She has lived all over our neighborhood and she is semi wild. She joined our family and I realized she was pregnant.. Her behavior was great.. She had the kittens and we kept two then fixed them at three months.. Catalina was also scheduled to be spayed but I realized she was pregnant again so didn't take her in. Now she is near giving birth, only comes in to eat, and is extremely aggressive to the adolescent kittens. I want her to have safe haven and to get her vaccinated then spayed after the birth. Can she be vaccinated while pregnant and other than the calming wraps do you have any advice? I do fear she's rabid but aggression is the only exhibited symptom and no rabies have been found in my area of late. Thanks for your great work.

      I had a baby 3 months ago and our make 6 year old cat has become aggressive. He always has nipped when any part of his body was pet except his head. He has been rubbing against my feet while I am sitting and then turning and trying to bite me while I hold the baby. He has attacked my mother in law when she was alone with the baby ( even when she was not holding the baby) and continuously stalks me or anyone when they hold the baby while she cries. He has circled the baby when she has been on the floor crying. He also attacks the other cat during cries or if she comes near me and the baby. He can still be friendly and loving, it's just starting to concern me with a baby. He safety has to come first. I've tried a calm collar and it didn't work. What can I do? He is loved and getting him a new home is the last resort.

      Rabies is transmitted through a bite with a wild animal, so the most important question is: has your cat been in contact with any animals that could have bitten or wounded her?Any contact with the saliva of some animal? Is your cat indoor only? Most vets won't vaccinate when a cat is pregnant. Does the aggression happen though only in the presence of the kittens? If so, you may want to keep the away from her and see if the behavior persists in their absence. There are chances that as whelping nears, she wants her kittens to be safe and is looking for a whelping spot with no other cats or kittens interfering. Adolescent cats are already big so she may see them as posing a danger to her litter.

      Sounds like a stressed cat and redirects towards you or anybody nearby. I would try to get him desensitized and counter conditioned to the noise of crying as it seems to be a trigger. Every time the baby cries from a distance, feed your cat something your cat loves, like a bit of sardines, dried fish or some other smelly treat your cat loves. When the baby stops crying stop feeding the treat. The purpose is to get your cat to associate crying with the treats. However, problems may be seen further down the road, when baby grows and starts crawling, then your cat may need the same procedure done while the baby crawls at a safe distance behind a baby gate if needed. Always keep an eye on baby and cat and never keep them alone unsupervised.

      A couple years ago I took my cat to the vet just for a vaccination shot. She had a very bad experience while there-was growling and hissing at everyone and everything. It took over a month for her to calm down get back to her normal disposition. Since then, every now and then something will trigger her and she will revert back to the hissing and growling-really ferocious and threatening. I've been so afraid of her that I have to scare her out of my bedroom and lock her out just so I can get some peace and have some time where I'm not terrified she's going to lunge and attack me. It's been quite a while since her last episode and I thought enough time had passed that it wouldn't happen again. But last night something triggered her and I had to lock her out of the room again. In the middle of the night she was clawing at the door and meowing so I attempted to let her back in. When she walked in the room, I pet her a little and she walked around nervous like, meowing, but when she jumped on the bed, she immediately began growling and hissing at me again so I had to chase her back out of the room. This morning, as soon as she saw me she began growling and hissing at me again. (Plus she had left pieces of poop all down the stairs for me.) Any ideas on what can be causing this behavior? I have noticed that if I lean over her (i.e., if I'm reaching for something), that can trigger it. Most importantly, what do I do when she's exhibiting this behavior? I'm scared of her and don't know what to do.

      my cat binxy (who we have had for 8 years) has all of a sudden be acting very aggressive to our other cat Christopher (who we have had for 3 years) they were aggressive to each other at first, this we knew! but after awhile it changed into play fighting now almost 3 years since we got him my cat binxy has gotten so aggressive to the point where if I hold the other cat he will growl at me. we don't know what to do, Christopher just went to the vet because of seizures. we got it all straightened out and he's better but with binxy attacking him it makes him stressed and worn out. Might I also add that binxy had always shared a house with at least one other cat...and he was never this aggressive he also has had all his shots (including rabies) i hate to have to do something to make him calm again but he's just not the binxy I had 8 years ago....

      I have a brother and sister cat that have been together for 8 years and have been best friends that love eachother. Out of the blue the sister cat has become very aggressive to the brother and is hissing and attacking him. It scares me because I've never seen them be like this and I don't want him to get hurt. It's just out of the blue. I don't know what to do and it is stressful for the boy because he doesn't understand.

      I have adopted a kitten that is approx. 4-5 months old. He is very, very aggressive. There isn't any one category of aggression that fits him. He growls at me whenever I look at him and talk to him, he is aggressive when playing, like he is really attacking the toy, he can't stand to be petted, or even touched. He growls constantly. He attacks my legs when I walk by him. I notice that he is less aggressive and threatening (but not by a whole lot) with males. This kitten came from a household that had a toddler and I'm wondering if he was tortured by the child. There seems to be no medical reason why he is this way. It's as if maybe he doesn't know how to make any other sounds other than growling, which I'm sure is not true. I said this to give you an idea that he growls constantly when I am around him, and never displays any other kind of behavior. He never meows or purrs, or displays any kind of positive behavior. He eats just fine, and his litterbox habits are fine. Please help!!!

      I feel for you kkramsey as my cat went through the same thing some years back. She was checked by the vet and all was fine, but she still had these episodes. I tried Feliway, it helped a bit, but it didn't make them go away. For a while I was convinced it was the carpet making her nervous as she sometimes got shocked by static, but I really never knew what was the trigger. All I knew is that she very stressed and chasing her away or cornering her, seemed to make it worse. If I still had my cat today, I would have tried using high-value treats. In your case, you can try bending over very slightly and letting a few treats fall to the ground so that she thinks bending over isn't threatening, gradually bend more and more letting more treats fall down. Be cautious though, I know many people getting scratched by their stressed kitties. I hope this helps, if your kitty is too stressed, she may not want to eat though, or you may have to try something extra yummy like dried fish or liver. Good luck!

      Haley, be careful holding your other cat when your cats are angry with each other as you may get a re-directed scratch or bite,I would use gloves just to be safe. If your other cat has seizures, these could have scared your other cat causing stress and a reason to attack. You can try tossing some treats to your other cat every time you hold the other cat. This may teach that "good things happens"when she holds the cat.

      Hello

      We have a 2 year old cat we were given as a present. The original owner told us that he had had a difficult start in life as he had been abandoned by his mother. He has always been somewhat anxious and gets startled quite easily. He doesn't like strangers but we've learned to manage that. What is difficult is that he can suddenly attack one of us in the family (usually me - the only female) for no apparent reason or when I make a sudden noise. The bites have been quite severe and I've been warned by my doctor that cat bites can be really serious and that we should consider getting rid of him. The thing is our oldest son (14) is very attached to him and would be incredibly sad if he was gone. On the other hand our younger son (11) is a bit scared of him and afraid to do the things he would do if the cat were not there. We don't know what to do - any advice?

      We have 2 neutered male cats that we have had for 5 years. They are not litter mates but when we adopted them they were in the same cage. They have gotten along great all the years that we have had them. About 2 months ago a neighbors cat that is an indoor/outdoor cat wanders on our deck while my cats and I were out there. We have a gate at the top of the steps and the other cat was nose to nose with one of ours and they were both VERY upset. So, I did the natural thing and picked up both of our cats and put them inside right away. Then a second later one of them started to chase the other and the one being chased ran under my bed, and the sound was horrible with the hissing, growling and horrible screeches! So, I seperated them, for a day or so. Let them get used to each other again thru a crack in the door. Then they were friends again, till the cat came back (I have talked to the owner about this situation). Then it happened all over again. I did the same thing, then they were friends again. The cat came back for the 3rd time and it happened again but this time I put a different cat in solitary for a couple days, the one that was so aggitated and hissing. I finally forced the issue for them to become friends again, and it worked. The next time it happened the other cat was not involved outside that I know of. Something got triggered, a memory or something and they were on the outs yet again. The cat that is doing all the hissing is also the one that keeps trying to hide. The other cat doesn't do anything, just looks at the one that is upset. He does chase him a little bit or he seems like he is trying to maybe corner him, but not all of the time. Today I let them out on my deck, they love it out here when it's nice out. The growling hissing one soon settled down and they were friends again. The minute I let them in.........the growling hissing cat was again growling and hissing at the other one that he had just been grooming his face! What in the world is going on? It's like a switch went on when they went inside and he became mean again! Currently, they are out on the deck, curled up in a chair with each other! Ugh! I give up, as to what is going on here. I am desperate to find a solution. :-(

      Hello I have a question about my seven month old brother kittens. Both of them were very friendly but today I let both my kittens go out and enjoy themselves, one of them came early (which one is little in size) and second one came little late(the elder one. He was born before the little one). After coming home, the little one suddenly started to bite and attack him. The elder kitten didn't fight back instead he tried to run away from him. I separate the little one many times but after some time he does the same thing over and over again. My brother said to me that the little one wants to play with him but the elder brother don't feel like playing. Just like when elder one used to attack him and the little one didn't like it. I asked my brother to take the elder brother to his room since I will take care of the little one. But at 4 AM he came to my room again and the little one started to attack him again. I managed to make the little one stop fighting and was able to put both of them together in bed. It's 5 AM and their sleeping peacefully again like they always did right next to each other.. But still why is he attacking? If you can help me please.

      I adopted a "breeder Persian", 4 yrs, had 5 litters. Had her 3 weeks. All of a sudden she won't let me groom her at all. Refuses to let me hold her and wipe her face with cotton balls. She must be cleaned each day (nose/eyes). She aggressively refuses to allow me to hold her and has scratched me violently twice. She is sweet and gentle otherwise. Any advise? I don't think she is socialized much.

      Sounds like a stressed cat. You can try Feliway and using a counterconditioning program where you use tasty kitty treats (try different kinds and find the one that she responds to the best, maybe even pieces of tuna or dried fish) to create positive associations with the cleaning. Use gloves and long sleeves to protect yourself, but be very careful! Cat bites and scratches can become easily infected. When your cat is sleeping on the couch, sit besides her, and you can try to show cotton ball and give treat, show it again, treat, then progress slowly to moving cotton ball near face/treat cotton ball near face/treat. Try not to hold her, this may make her more distrustful. Try to work on making the cleaning as pleasant as possible so that she doesn't need restraint. Lots of time and work, I know.

      I just started fostering my neighbors cat because my neighbor is having to move and can't take him with her. He is a year old fixed. He is a very sweet cat, but when he came to my house he has been hissing, growling, and hiding and batting. I know that it is probably just the fact that he is in new surroundings and is terrified. But I want him to understand he is safe.

      Hi Pamela, you will need to gain his trust. One if the best ways is through not forcing interactions as of yet and letting him know that you are the one feeding him and you won't harm him. Move slowly, try to avoid making loud noises, talk to him in a calm voice. He'll figure things out eventually! good luck!
