Symptoms of Poor Hamster Health or Illness

Hamster Illness Can Be a Serious Matter

Although hamsters are pretty easy pets, they are very small, which means that injuries and illness can quickly become a serious matter. They are actually pretty good at hiding their illnesses until it's nearly too late, which is why it is important to keep a close eye on any changes in your pet's regular diet or routine.

If you notice any signs of illness in your hamster, you need to see a veterinarian as quickly as you can.

If you think that your little furry one is sick or injured, try to keep it warm. If you notice that it is not eating on its own, encourage it to take food or water by a dropper, until you can see a veterinarian.

Signs of Illness:

  • Loss of appetite
  • Inactivity
  • Huddling in a corner
  • Ruffled or unkempt coat
  • Sneezing
  • Discharge from the nose or eyes
  • Wheezing
  • Wetness around the tail
  • Diarrhea
  • Hair loss
  • Humped back

Common Hamster Illnesses

  • Abscesses: These are pockets of infection that can form from minor breaks in the skin. In many cases, abscesses occur in the cheeks from cuts caused by food. If the hamster looks like it constantly has food in its cheek pouches, it may have an abscess, which a vet will need to drain.
  • Respiratory Infection: Respiratory infections can lead to pneumonia. You should watch for sneezing, discharge from eyes or nose, wheezing, and labored breathing. Don't worry about occasional sneezing, unless there is loss of appetite, decreased activity, wheezing or difficulties breathing accompanying it.
  • Wet Tail: A wet tail is one of the more common hamster illnesses, most commonly caused by stress, crowding, and diet changes. Although it can be fatal if not noticed soon enough, it is curable. Watch for signs of diarrhea (causing wetness around the tail), lethargy, loss of appetite, a humped back, and a ruffled coat.
  • Diarrhea: Not all hamsters who have diarrhea will have a wet tail. The most common cause of diarrhea in hamsters is the overfeeding of fresh vegetables. Unlike wet tail, there is no loss of appetite or decreased activity. For the most part, the hamster will appear normal. Do not let diarrhea stay for prolonged periods of time, as dehydration becomes a big concern. You will want to withhold fresh foods for a few days and resume only if the diarrhea is completely resolved; you can start giving fresh produce again, but slowly.
  • Skin Diseases (including mites, ringworm, allergies, and skin infections): These are the most common skin illnesses associated with hamsters. Watch for flakiness or redness of the skin, hair loss, lesions on the skin, or if the hamster appears to be scratching more. In these cases you will want to see a vet to determine the exact cause of the skin concern. Pine and cedar bedding can cause skin irritation, as well as lung problems, so avoid these beddings.
  • Hibernation: Watch the room temperature where the cage is. If the temperatures fall below normal, the hamster may go into a hibernating state, where they can appear very still and breathe more slowly. Your hamster is not dead or dying, in this case, but you will want to rewarm the hamster.

My hamster is dying

AAMoss on May 03, 2020:

My daughter has a winter white we have had for several months. She is still eating but has more wet poop than usual. She does not appear to have a wet tail and her eyes and skin look good. We gave her new treats with veggies. Could this have caused it? Should I be concerned?

bhus15 on April 20, 2020:

I've been noticing a weird swollen anus on my new Syrian hamster, Tyson. I don't think it's a rectal prolapse because nothings coming out of it. It's just puffy and red. He has also has a bit of a damp tail. Tyson is behaving normally, eating, drinking, sleeping and being his peppy self. I'm just worried. Help, please.

Me on April 09, 2020:

My hamsters penis is larger than normal and is a purple blue color. Kind of like a bruise. He is a tan and white long haired syrian that is two years old. Does anyone know is this is just normal or I need to seek help? Thanks in advance

Hamlet (The Hammy's Name) on January 31, 2020:

hi guys, I have a teddy bear hamster and his fur is matting and his back is kinda hard and he is struggling to walk. it is almost like a scab that spreads. i am using a medicine on him and it seems to be helping but if anyone know what it is that would be great. I have been trying to research this disease for hours. if I know what it is it would really help me research this disease so I can cure this little guy faster. Thank you! I hope all the other hamsters do well also!

chi the hamster on June 20, 2019:

Chi is a Chinese dwarf hamster. about a week ago I took him out of his home to play and he looked fine. very active, eyes wide and back flat. just today, about a week later, I took him out again and I noticed he looked tired but when I looked closer I realized he had goo around his eyes and he kept them mostly closed although being able to open them. he also had an arched back. he’s rarely active while in his cage, he used to be a lot more, but now he just sleeps and comes out to eat or drink. I’m worried about him. this happened to my friends hamster, except hers had hair loss around the nose. mine doesn’t. I’m going to take him to the vet tomorrow, should I be worried? does anyone know what this is? I’ve had him for about the year and I’m afraid his time is coming but i don’t want it to be because of sickness. help?

Oni on April 18, 2019:

My hamster does long deep squeakes in her sleep and i wake her up and get her out because I’m scared she is struggling in her sleep but I got her out today and she was sneezing continuously and clear snot was flying everywhere. And her mouth is all surrounded be saliva. Sometimes she will do a little jump when she sneezes. There aren’t any exotic vets that I know of in my area and I need help

Madelyn on April 15, 2019:

Please help me. I have a male Russian Dwarf, almost a year old. He recently got out of his cage for at most a day and a half while I was at my mothers house and he hasn’t been the same since. His back in hunched, I haven’t seen him touch his food, but he seems to stay in one area, not moving much. He won’t run on his wheel and he usually doesn’t let me pick him up or pet him, but recently hes been limp and doesn’t do anything when I pick him up. When I first found him he was in a corner, shaking, awake but his eyes didn’t open. I gave him food, which he didn’t eat, I set him in front of his water and he sat there and drank for over an hour. His eyes are darely opened now and it’s been a day. He hasn’t been active, hasen’t eaten, and has stayed in the same spot. I plann on bringing him to the vet tomorrow but I’m scared for his health, maybe he ate something while he was out or something else happened?

... on April 15, 2019:

Jovita on January 08, 2019:

So, my hammy recently had diarrhea but I’m pretty sure it’s not a wet tail since her bottom isn’t wet/has poo. Also, my brother has been bothering my hammy a lot. Idk if my hammy did diarrhea because of stress from my brother or something, can someone tell me if my hammy is sick?

sarahhxox, your hamster needs to be taken to the vet, he or she has "wet tail". You can look it up, but if your hamsters' stool is not solid, he/she is sick.

Hello. My hamster (which is a long haired teddy bear which is around 1 year old) has been noticeable drinking large amounts of water and losing her apatite. Although she is active, she will not eat treats or much food and refuses to stay away from her water bottle. I have looked up the symptoms but I have got nothing definitive. Please help!

carlehe on May 28, 2018:

Kate on May 27, 2018:

Hello, My hamster has been around for about a year now, but I'm not sure if it is getting old or something else. Behind it's ear, it is red and has red marks we are not sure how it got that. And it's eyes have been closed for a few days, and it keep rolling around in it's hay and it keeps squeaking.

Kayleigh F on May 26, 2018:

Hey, my boyfriend bought a beautiful creamy grey Russian Dwarf hamster who we've had for over 6 months now, therefore, she's very loved and will be dearly missed if she dies. Sadly we recently noticed a lump on the side of her stomach near her rear leg. We took her to the vets and the vets claimed it was a tumor and had given my boyfriend a painkiller (Metacam) and an antibiotic (Baytril) we've been giving it to her as the vet recommended us to do and it has been helping to make the tumor smaller. However new serious symptoms have popped up and is, therefore, looking for opinions and ideas on what to. We are in the process of getting surgery for the tumor to be removed but the cost has made us have to wait longer and the symptoms will cause an issue for us and the vets.

Currently, at the moment, she is unable to eat and visible signs of weight loss are seen. Her eyes are almost always close as if unable to open. She is bleeding from her vagina area which is a worrying us. Shes also drinking a LOT of water and doesn't go far. She's shaking and seems unable to move to places where she usually can. This is causing me and my boyfriend and his family a lot of concern. At the moment we believe its either her teeth are too long or its possible sides effects of the medicines, however, we aren't vets nor had hamsters long enough to be considered professional hamster handlers. Any opinions would be greatly appreciated thank you!!

Mary Helen Mena on April 17, 2018:

I have a female hamster; she is about 1 year and a couple months old. She was fine a couple days ago, but yesterday I noticed she was very thin (even though she always has a lot food and water),and her eyes were closed with a sticky discharge. I took her to the vet and he told me she has parasites and infection because of the parasites. He dewormed her and gave me antibiotics to treat the infection. She doesn’t want to eat or drink water and is walking funny.I checked her pouches to see if there was something wrong in her mouth, and everything was fine. No wet tail, no visible trauma, no ear discharge, no visible diarrhea (her bottom is clean), no visible skin problem. I need help, there’s no small animal vets around and I don’t want my hamster to die.

Thanks in advance.

g.f. on November 25, 2017:

i woke up recently to see my hamsters back hunched and him walking sluggishly. other than that he seemed fine but the next day he was standing in the corner not moving, when i tried to pick him up he squealed at me and proceeded to lie on his back. during this he peed and i noticed it was extremely dark, meaning he was dehydrated. after he calmed down i tried to give him some water but he refused. he seems like he's in a lot of pain and constantly squeals without anyone touching him.

i dont know whats wrong and im worried. there aren't any vets less than an hour away and even if there were, i couldnt afford it.

My hamster was about 18 months, Last few days, I noticed him not running on his wheel, he just sit on the side of the cage. Lately, he peed on his favorite area (where there's few sands) and I suddenly saw him laying there, his hands and foot are shaking but the right foot and body are stiff, I think it's stroke or what, he's eyes won't close after I cleaned it with cotton buds because it was teary that almost close his eyes. His bottom is dirty and wet, but I think it's because he peed lately. He is stiff and can't move his body but he is trying to stand, to move! What is happening to my hamster? Please help!

Sarah on July 11, 2017:

My hamster is not showing ANY signs of illness apart from sneezing alot, is this normal?

Cameo on June 27, 2017:

I sometimes get bothered by some things that say, if your hamster has so and so, take them to the vet. I get bothered because there are not a lot of vets that take hamster, and if they do, they probably only have a tiny bit more experience then you, so your paying all that money when you can just go look up how to do it on the internet, and buy some medicines yourself. So for all the people who say, go to the vet, you are not useful at all. This is a useful website, but what would make it better is if you add how you can prevent these, and some remedies.

Hannah on June 04, 2017:

For all those people who are saying that their pets appear to be ill, then take your hamster to the vet IMMEDIATELY! It may not be anything serious, but get it checked out by a medical professional to help your hamster have a better quality of life

Katie on June 01, 2017:
