How to Spot a Sick Mouse: Common Illnesses in Pet Mice

I love all animals, especially small animals such as rabbits and rodents.

Did you know that human illnesses can affect mice too? Learn about the common illnesses that can afflict pet mice, from colds to tumors.

Did you know that human illnesses can affect mice too? Learn about the common illnesses that can afflict pet mice, from colds to tumors.

The Same Illnesses Can Affect Both Mice and Humans

We all get sick from time to time, and this includes our pets. Even tiny little mice can get sick, too, although it can be harder to tell. Illness can include anything from very minor allergies to full-blown cancer.

Mice are mostly nocturnal creatures that are highly active—females in particular— and will often disguise their ailments so predators don't see them as weak or easy to pick off.

If You Are Sick, Take Precautions Around Your Pet Mouse

Mice are very much like humans, so many of the illnesses we suffer from can also affect mice. If you have the flu, salmonella poisoning, unexplained vomiting, norovirus, or any other contagious illnesses, then wash your hands thoroughly and avoid sneezing around the cage. Even better, remove the cage from your room and have a family member or friend come round to care for your animals.

Mice can, in fact, die from influenza. If their tiny immune system can't fight off a human sickness, it can kill them. Illnesses like salmonella and (in particular) norovirus can kill humans.

How Diarrhea and Dehydration Affect Mice

Mice don't vomit, but they can have severe diarrhea. Dehydration can kill a mouse or other rodent in less than 48 hours! And mice do not have the same complex minds as we do; they can't be made to understand that, if they have diarrhea, they need to drink and keep themselves hydrated. More than likely, a mouse will not eat if it is ill.

Mice are vulnerable to human illnesses.

Common Illnesses in Pet Mice

Here are some common illnesses of pet mice, with their symptoms, treatment, and some notes about prevention.

The Common Cold

Colds in mice are very similar to colds in humans and often clear up by themselves. The symptoms include sneezing, watery eyes, shaking, and tiredness, much as in humans.

Make fresh food and water available at all times, and keep the cage clean and as dry as possible. Keep the cage out of drafts, sunlight or high temperature. Make sure it is at a constant comfortable temperature for your mouse—not too hot, not too cold. A cold usually clears up in under a week, but if the mouse seems to be getting worse, or there is no improvement in three or four days, then I would go to the vet, as it could be a more serious problem.

Salmonella Poisoning

Mice are highly susceptible to food poisoning, as we well know. So make sure your sink is clean when you fill up water bowls or bottles for your mouse; fill them BEFORE you wash a raw chicken in the sink or otherwise handle raw meat. Thoroughly rinse the bottle with hot water each time you use it.

Do not handle food or water (this includes the outside of the bottles, as they may touch or lick them) or touch your mouse until you have washed your hands with anti-bacterial soap and hot water for at least a minute or two. This is for your own safety as well as the mouse's. Do not touch cage bars either; we know mice touch and lick them constantly, so infection is easily spread.

Symptoms include diarrhea, shaking, dehydration and loss of appetite. Diarrhea can show up as moist, off-color poops instead of the usual dark poops. If this infection does occur, force your mouse to drink as much water as it can, carefully, using a small eyedropper. Do not leave the mouse unaccompanied; it helps to reduce stress if a loving owner is there to support him or her. None of us like being ill alone.


Diarrhea is a common problem, usually deriving from stress, too much fresh food, salmonella, ordinary upset stomach, or the final clearing of constipation. It is very common in older mice. It is nothing too serious; just make sure your mouse is getting plenty to drink. As I mentioned above, you can use an eyedropper to gently force it to drink. Dehydration causes death in hours, so be careful.

Diarrhea is not usually vet-worthy and can clear up easily on its own; however, if it persists for more than a day or two, go and have it checked. Keep your mouse in conditions as clean and comfortable as possible. Be sure plain, fresh food and water are available at all times. Rest is needed.

Skin Allergies

This does not include mites (see below) as they are not an allergy. Skin allergies are another common problem easily solved with extra care. Often, mice will have an allergy to bedding, such as certain wood shavings—usually ones bought from pet shops. These shavings can be dusty and may have been sitting for long periods, or if they are really cheap they might not have been treated right. Mice can get allergies from some dry meadow hays and dusty hays, which can irritate eyes and cuts as well as skin.

Mice can have food allergies, too: vanilla (if used in the water or cage), hamster feeds, fresh foods, and herb-based foods are the most likely to cause allergies.

It is easy to spot a skin allergy. Signs include:

  • Baldness
  • Excessive scratching (other than grooming)
  • Rubbing against items in the cage
  • Outbreaks of redness, swelling or clusters of bumps
  • High stress levels
  • Obvious discomfort
  • Bleeding scabby skin
  • Lethargy

These can happen even up to a week or so after using a new product. Remember, don't use more than one new product at a time.

  • Feed: If you are changing to a new type of feed, don't go out and buy loads of different treats, because if an allergy breaks out again after several days it will be hard to tell which product caused it.
  • Bedding: Use up an older supply when changing bedding so you are using one new thing at a time, and you can locate the source of any problem and bring it under control.
  • Cage Cleaners: You must be careful to only use small-animal cage cleaners, such as Johnsons, as they can be wiped off easily, and be sure to rinse thoroughly because over months or years even appropriate cage cleaners can cause allergies on the skin! If anything causes even a small reaction in your pet, discontinue using it. Although even if your own mouse is allergic to it, it's possible a friend's mouse or hamster can try it out.

Treatment includes bathing the area in a warm water and salt solution, using a piece of tissue or a cotton bud. Do not bathe more than twice a day as this can make the skin dry and cracked. Don't bathe the whole mouse, just the affected area. Try to dab the mouse as dry as possible afterwards. Don't leave a mouse to sit wet and cold to dry off; this includes eyes and ears.

If the mouse continues to scratch, clean out the whole cage and make an appointment at the vet's; it could be mites. Be careful to monitor the mouse as cuts on the skin can become irritated or infected. Ointments are available but often they are too strong and not much use; they can make things worse. I recommend salt water solution; it is safest for your pet.

In rare cases, extreme allergies can cause death. If you suspect your mouse has a serious allergy that is not clearing after a few days—bear in mind that it can take a few weeks for fur to grow back and cuts to heal—better go to a vet.


Mice are prone to getting mites. They usually come from damp, dirty bedding, such as wood shavings that have been left outside or not cleaned out regularly. Also, wash your hands before touching your mice, if you have been outside in the grass or touching other animals because you can transfer mites to your pet with your hands.

The symptoms of mites include:

  • Excessive scratching (other than grooming)
  • Fur loss
  • Loss of appetite
  • Raw or cut skin
  • Scabby skin
  • Mites visible in fur (back and ears are the most common places)
  • Mouse appearing distressed
  • Mouse rubbing on toys
  • Aggressive behavior or other behavior changes
  • Looking to be picked up constantly

Go to the vet to have mites checked out. You can treat mites with ointments (make sure you finish your course of treatment) and by cleaning the cage thoroughly each day.

Eye Problems

Often mice will get the odd runny eye, a small amount of discharge, or squinting, which comes and goes fairly quickly and never needs treatment. However, swelling, crusting over, or white lumps on eyes can be a sign of severe infection and the mouse turning blind. Be aware that there are other more common possible explanations for a runny eye: stress, anxiety, something caught in the eye, or an allergy.

The best way to keep these problems at bay is to keep the cage clean, keep your hands clean when handling the mouse, check your mouse daily and if symptoms keep occurring or get worse, go to the vet's. This is easily sorted out with treatment and rest, but sometimes blindness is the result, so get the problem checked if it keeps happening or gets worse.

Discharge can come in different colours: clear, white, yellow, green, orange, and red. A watering eye could just mean that the mouse is tired.

Kinks in Their Tails

If you have a mouse that has a kinky tail, the possible explanations are rough handling in early life, injury in a fight, spine problems, genetic kinks, or having had it trapped in something like a door, a cage ladder or a toy. Kinks are harmless unless the mouse displays problems with walking or balance. Nothing can really be done for them. Mice whose tails have kinks, notches or lumps should not be bred, even if their health and behavior are fine, because they may pass a gene on to their offspring that could cause spinal problems.

Wet Tail

This is not very common in mice; it is most common in hamsters, gerbils and guinea pigs. It is usually caused by urine leakage or problems using the toilet and can be treated. If left untreated for long periods of time it can be fatal. The symptoms include:

  • Wetness around the genitals and lower back
  • Discomfort
  • Seeming confusion when using the toilet
  • Messy toilet regime
  • Shaking
  • Loss of appetite

Wet tail can be mistaken for a one-time occurrence of wet hindquarters from the mouse sitting in a bowl of water or against the water bottle. The easiest way to prevent this kind of soggy bottom is to keep the cage clean and dry and make sure the water bottle is not faulty; leaking water bottles can be a problem. If using a bowl switch to a bottle. If you suspect wet-tail disease, as opposed to the mouse just sitting on a wet patch or water bowl, go to the vet's.

URI (Upper Respiratory Infection)

This can be fatal quite quickly to mice. It is caused by dusty sawdust (not wood shavings), dirty or damp conditions, unhygienic routine, or filthy bedding. The symptoms include:

  • Laboured breathing
  • Shaking
  • Loss of appetite
  • Watery eyes
  • Lethargy
  • Sitting hunched over or lying down
  • (sometimes) Hair loss

Your mouse will appear very sick with a breathing problem. Get them to the vet's as soon as possible; this illness must be checked and treated properly or your mouse is likely to die. Clean out the cage thoroughly, check for any damp or problems, and keep it in good condition; URIs are most common in dusty or dirty conditions, tanks, and bin cages.


Influenza is similar to the common cold but more likely to become fatal. The symptoms are similar but the mouse will be in much worse condition:

  • Runny eyes
  • Sneezing
  • Wheezing
  • Shaking
  • Fluctuating body temperature
  • Lethargy
  • Loss of appetite
  • Dull coat

If these symptoms persist or worsen, or the mouse becomes limp and struggles to walk, then the mouse must go to the vet's or it could die. To prevent influenza, do not touch your pet if you have flu, as mice catch it from humans. If you have been out in public, wash your hands with anti-bacterial soap, as this will keep this and other problems (such as winter vomiting or norovirus) from spreading to your mouse. Have someone else care for them if you are too ill, and keep things as clean as possible. Also, clean out the cage regularly and make sure the mouse has plenty to eat and drink.


Mice are prone to tumors, especially old mice, feeder mice, and mice in poor health. Most commonly, these tumors are benign fatty lumps on the sides of the mouse and around its back end. You will be able to see and feel them; they do not go down when the mouse stretches.

Get them checked. If they are cancerous, there isn't much you can do. The chance of a mouse surviving the operation is less than 50%, as drugs, stress, infections and recovery are very hard on a tiny mouse, but the choice is up to you. Benign fatty lumps are usually not a problem, and often a vet won't operate on them. But get them looked at just to be safe.

I got three females the other day and ive only really been seeing two of them. Figured the other one was just shy but i saw her today and her face was HUGE. it didnt look like that yesterday. Any ideas?

Serena on June 15, 2020:

So I caught a wild mouse in a humane trap. Unfortunately we went weeks without catching it so I forgot about. I smelled a bad smell under my sink where a trap was. Checked it and going the little one. I thought it was dead. We've been calling the mouse Jerry since we first saw him running around the house. He wasn't dead though he had lots of pee and poop in the trap. Poor baby looked to be on deaths door. We put him outside and realized Jerry is still alive. So I took a bowl of water and cloth and cleaned him gently. Dropped a couple droplets if water and his head and he started preening. Idk if he's going to make it. He's in a big tote with a towel and a cap of water and a spinach leaf and peanut. He's laying down. He sniffs the food and went to the cap off water and gulped some water.

Jay on December 05, 2019:

My cousin bought two mice from Petco a few days ago. Everything has been fine until last night. The names of the mice are Baxter and Bandit (both males) my sister found Baxter last night constantly flipping around while trying to walk, almost like he’s trying to one side of his body on the ground. He’s shaking too and he won’t stand up or look up straight.

Dave on October 25, 2019:

Caught some house mice. One is feeling tired constantly and does not fight back against her siblings. Not that i care much for the mice but i was planning to take them into care once i captured all the ones in my walls. Also i'm kinda curious why such a young mouse would already be sick.

Mouse lover on August 05, 2019:

My pet mouse is walking strange and is laying down on his ear so if anyone has any advice please tell me.

I NEED HELP ASAP!!! MY MOUSE IS GOING BLIND! It started off 3 days ago with a watery right eye and now it's started to turn a pinkish colour when it catches the light. WHAT SHOULD I DO!

Crystalshine McEwan on March 28, 2019:

Still not a mouse. Ffs.

I don't have mice, so I was here for advice for a friend. I am not sure if I can trust it though. I do have rats, and I echo the fleece for rodents. And keeping them in a location that is a good steady temp and humidity is one of the best things. It should not be damp or dry, or hot or cold. It has too be climate controlled, and clean. That basically reduces most URIs off the bat. Because the dust and spores are gone this way, and the ammonia is under control, so they thrive. I think mice would equally thrive in this environment.

Anonymous on March 18, 2019:

1st that’s not a mouse lol. It’s a hamster. 2nd, You have to be REALLY sanitized to handle and clean the mouse’s cage. 3rd. Ya URI is sometimes caused by bedding, the dust. The dust is consumed by the mouses nose and it disrupts the nasal passage and causes uri.

I use fleece for my 10 mice, it’s a lot healthier. I would switch to fleece or fabric

Crystalshine McEwan on March 02, 2019:

That's not a mouse.

Person on September 21, 2018:

My pet mouse recently developed three punctures near its bottom on the underside. Two are fairly small and ooze pus, and the last one is a huge bubble-like brown thing, also oozing pus. My cat (who doesn't even know I own mice) recently brought in a dead wild mouse with the same thing. I'm worried its a rare disease that can kill Roger :'( And the nearest vet in my area that treats mice is five hours away

Mouse lover on August 24, 2018:

@Elliander Eldridge

There's nothing you could have done better. Cats have a certain bacteria in their mouth that once infects little rodents or birds it kills them, often times not at once, but over a prolonged period of time. I know you mentioned that there was no visible bleeding and certainly not bruising, but all a cat needs to do is gently press its teeth into a rat/mouses body and the toxicity will kill them. About a month ago I found a baby oreol in cats jaws. Same scenario, no bleeding or cuts, so we put him in a shoebox with bedding and holes, gave him seed-based food created for baby birds every half an hour, put a saucer of water in the corner, and a heat lamp on the far side of the box. Over the course of 3 days his eyes gradually shut, and he descended into a state of contentment and peace, until one day he died. There's also a chance the shock took him, albeit, usually the ramifications and repercussions of shock happen the day after, not a few days. Also, he could have been sick, as that could explain a wild mouse not fighting to try and escape the palm of a hand. However, illness with few/no symptoms indicates the lack of an existence of an illness. He also could have been old, or the bedding you used could have brought an upper respiratory disease to that particular mouse. But how would you have known all these factors and possibilities? To sum it all up, you did your best and tried to humanely rehabilitate a delicate and time-consuming mouse, and next time (hopefully there won't be a next time) try to imagine yourself in his/her situation. A giant furry creature bit you and there's poison in your veins. Or you're in shock from an encounter with an EVIL GIANT WHO HAS NO EMPATHY AND DOESN'T EVEN KILL TO EAT(Srry not a cat person at the moment), and what to you need? Warmth (provide a blanket, hot bottle, hand or heat lamp), food (preferable hand fed solution as to not waste valuable energy on physically obtaining food or to curb some steps of digestion), water (find a way to hydrate your mouse), and for the emotional side.... Hope. I know, it sounds super ridiculous, but rodents are social creatures who form strong bonds between family. They may need someone to come in contact with them, and it's clear they're away from everyone and everything they love. Pet her head, talk to him, but not when you're sick (them being highly susceptible to any diseases you may carry). But yeah, to reiterate, you did a pretty good job of keeping your mouse safe and happy for the last few moments of their life, and for that I commend you. Gouda job dude! (sorry i'm two years late!)

Leah on October 21, 2017:

My mouse is tired seeming, he shakes, he wont respond to me in anyway. Usually when I pick him up he runs up my arm and hides in my hair now he balls up and stays still. after I had put him back in his cage he fell onto his side and did not move. I am worried for him and will accept any help I can get.

Tori on October 07, 2017:

This morning, i checked on my mouse and he would not wake up. He was breathing, but his eyes were closed and he would just not move. I came back later and he was acting very active as usual. Running ip and down the tubes and running on his wheel. He was eating fine and drinking water. But I noticed that he was a lot rounder than usual. He looked kinda bloated. His hunchyness even made him walk a little funny. What could his problem be?

Lokesh on March 28, 2017:

my mice is breathing deep please help me.

taba55 on February 23, 2017:

@elliander . It's nice that you tried to save that mouse. I'm not a mouse expert but have started working with them a few weeks ago and I think the mouse you tried to save had been injured by the cat (green marks may have been a bruise). It would've used its legs and been more mobile if it's limbs were not injured.

I have a question for people out there though. A mouse was injected with a drug through IV and it kept licking it's tail afterwards (many times during the hour post-injection), is that common?

Sarah on February 19, 2017:

I have one mouse. The other died after about 4 days of refusing to leave her sleeping place and continually burying herself, and the surviving mouse appears to be doing the same. I have no way to access a vet within a year. Do I just let my only mouse die?

Elliander Eldridge on May 17, 2016:

Hi, I was hoping you could provide insight as to a situation we went through:

One of our cats caught a wild mouse, and just played with it until we could get it away. (it was the first time in a long time) There were no punctures, no bleeding from the mouth, or any other visible signs of injury. It was in shock though with an extremely weak pulse. Gradually, in the warmth of my hand, it came to, and we gave it some bedding with some food and water that was safe and warm. That evening breathing was heavy and it had no use of it's hind legs, but moved around with it's front. The next day it was much more relaxed, and it started to eat at least pieces of raw sunflower seed and drink water. It was more relaxed with us. The next day it seemed content, it's eyes pressed together with what looked like a content look with I gently stroked it (to dry it since it got water on it) and it was starting to regain movement of it's hind legs. It was testing them, stretching them, and able to rest on them. Wasn't really using them yet though, That night I checked on it and made sure it drank water. The following morning? It was dead. It's eyes were closed, and it was in the position it would usually sleep in so it went in it's sleep. It's body was stiff and there was a slight green on it's belly fur. What happened? It seemed to be making a steady recovery, then just died. Is there anything I could have done differently?

Please help someone! I've seen a vet for my mouse, who keeps scratching very badly, and he says it's not mites. But it's gotten worse, very sore/inflamed. She has all symptoms of mites, but then also too of allergy, as there is apparently some overlap. Any advice PLEASE? So worried for her.

Her cagemates are all seemingly fine, which may suggest that it's not mites. I've heard that too much protein in the diet could be the cause, so I'm working on reducing this now. PLEASE HELP, SOMEONE!

My mouse is almost a year old. When we got her she was the fattest and biggest of the group of four. She has been acting really strange, she can't seem to hold up her head, she can't walk correctly and she has gotten skinnier every day. I can feel her spine and hip bones. I haven't felt for lumps but there is nothing prominently wrong with her. I just want to help her. If she is suffering and there is nothing we can do j don't want her in pain

Hey. I am petting 2 white mice Rose (female) anf berry (male).

Berry has been fine. But rose seems to have grown something large,the size of a kidney bean under her tail. I will be taking her to a vet very soon. Could you possibly let me know what it is?

Our pet mouse seems to be very inactive. He looks a bit more rounder in his belly and midsection, but you can feel his spine very prominently. He hasn't been running on his wheel as often as he used to, and he tends to sleep more than he used to. His eyes aren't as sparkling anymore; and he tends to squinch them instead of having them wide open. His breathing also seems a bit more heavy as his whole body moves every time he does. Any ideas as to what could be wrong. He's also about (I'm making an educated guess) two years of age. We used to have two mice, but the other one died of a severe brain infection. Given that they were brothers, I was wondering if perhaps it could be a genetic ailment.

I brought a 5 week old mouse today and she has been sneezing and peed a pinkish-red colour, what is wrong with her??

plz help!! on July 03, 2014:

i know your specialty is in regular mice, but i have a dwarf mouse named yoyo and ive had her for about 4 months, she is usually active and running all around her cage, but for 2 days she has been inactive, and really tired looking, she is squinting a lot too, it seems she has become more aggressive also. i do not have the money to take her to the vet bc my family is very poor. do u have any home remides or tips in mind?

My mouse, Snickerdoodle, is not acting quite right. After his fellow mouse died, Oreo, he hasn't been looking too good. He is missing patches of fur near his shoulders, discharge from his eyes, shaky walking, lethargic behavior, his eyes have also changed color, and I think his poop has lightened. I have not taken him to the vet yet. He also looks a little bloated in the stomach area.

I really need help. Should I just put him down? What do you think? Is there even any hope for her?

I have had my mouse Harrison since March and lately he has been acting really strange in addition to a deteriorating health. I plan to take him to the vet but until I am able to get an appointment I was hoping you could give me some insight. It's only been about a week or so since I noticed a lump on the side of his neck, just in front of his shoulder. It was fairly small when I first spotted it but now I am sure it has gotten bigger.

Harrison has the same energy level as usual and is eating and drinking normally. However, he scratches abnormally hard at his ears, to the point that they are scratched up and he squeaks every time he touches them, and he makes very strange noises that I have never heard from him before. He especially makes these noises when he is grooming himself, which he is starting to do way more often than usual (but he only focuses on his nose and ears). I am really worried about Harrison and don't know what to do or expect next until I get him to a vet. What do you think?

Sometimes just let nature take it's course, bulging eyes are usually agitation or distress in young mice this can be common. It is difficult to treat a mouse especially a wild one they can die of shock, it's best t leave them alone.

Well we are renting this house, and there are some mice time to time. The 2 baby mice ive seen are both really wet looking soaked, they feel wet not only in lower areas. And one recently seen has bulgy eyes. We feel bad but we don't know what it even is. Any ideas?
