A couple of days ago, I noticed one of my mice (Molly) had a big lump on her side. I'm getting worried about her because it might be a tumor. She just suddenly got this; but she seems just as active and eats like she always does. I don't know whether it is hurting her or not, and whether I should take her to the vet or leave her and see how she is for a few days then if it gets worse take her to the vet. Please help me, what should I do and what is it most likely? Thank you

    I had the same thing happen to my mouse, Xion. I'm sad to say that even though the tumor wasn't hurting her, it got larger and larger as time when by. In about three months, it was as big as she was and I considered putting her down. (The tumor was large and red, and had spread from her side, down her leg, to beyond her anus. It looked painful, but she showed no signs of pain and still walked, ran, and ate well. )

    After debating this a few days, I went to play with her and her sisters since she showed no signs of pain nor discomfort, but I found her dead - she'd passed in the night by herself. I suspect what both our mice have was a mammary tumor since they're both girls and it was a larger tumor growing on their side. My advice is not to take her to a vet now since there is very little they can do for rodents. (Had one overdose my Chinchilla.) I just adise enjoying the time with her you have left, her life expectancy is now about three months, but I know it is a hard thing to deal with.

    The tumor may become larger than herself, in which case, you may want to consider putting her down if she cannot walk much more. In this case, you probably would not want to take her to a vet either considering they will charge you about one hundred dollars for the euthanasia. I've learned a good way to put mice to sleep in the most dire of times is to break off about half of a pain-killer for humans, such as advil ect, and give it to the mouse in her own seperate cage. (So no other mouse may eat it as well.) This will put her to sleep in the most painless and humane way I can think of. (I had others suggest trapping her to which I refused.) Anyways, I hope you the best of luck and enjoy your time with Molly. I'm actually taking care of Xion's sister as of current which is how I ended up here, but I thought I'd share my experience with you. I hope this helps!

    Molly is 10 months now I think. Thank you for your comments and for the advice! Very nice of you :)
  • Imogen - 2011-09-03
    Molly is 14 months now and she's got less active and eats less. She looks ill: I'm prepared for her to die. Thank you so much for the advice, I really appreciate it
  • Claire - 2011-09-29
    I'm sorry it seems as if she's passing. During the time between my past comment, my other mouse passed, and my oldest mouse has developed a state similar to Mollys. The tumor as I call it, doesn't seem to affect her personality, nor does she respond if I touch it, but it is starting to restrict her movement. She is eating as usual, but between the past couple of days, she has begun running less and less. I can see her crawling about now, but I can also tell the lump is adgitating her. She keeps licking at it and cleaning her foot. I'm almost positive her time is near as well.

    As future advice, I'd say if you would like your mice not to develop tumors or cancerous bumps, I'd advise feeding them blueberries - expensive, I know, but I have recently learned that this can extend a mouse's life span and chances.

    If push comes to shove, I may have to put her down, and rather than paying large sums for the euthanasia, I've already made the choice to slip her a human sleeping pill - a process advised to me by a vet when faced with putting a pet mouse or rat to sleep. (The money is huge. I had to put down my Chinchilla and rat, so believe me.) Anyway, the important thing is that you gave Molly a beautiful and full life away from the cruelties of being a small rodent as she is. It makes me very happy to know I gave each and every one of my pets the best life possible for them, and if you ask me, I think they're happy too.
  • Imogen - 2011-10-02
    What good advice! I think I might give the blueberries a go. Yes, I'll continue giving Molly the best life possible and I'll try and keep her warm and happy. Thank you, I really appreciate all of your help.

Hi, a while ago I posted about Molly, my 14 month old mouse having a tumour. It seems to have got worse now, as she isn't active, has runny eyes, and shivers in your hand. But she still eats (although not as much as before.) I don't know what the best thing to do for her is, please can I have some advice? Thanks, I'm worried about Molly.

    Thank you so much for replying and for the advice-yes, I might try that soon so she isn't cold. I will consider it as this really isn't like her at all and I'm expecting her to die. I hope she doesn't die soon, but I think she will. I'll do all I can for her though: I really appreciate your advice, thanks. That's what I thought
  • Claire - 2011-09-30
    Her case doensn't sound good. It seems to be a combination of what my two mice went through. If the vet advises you to put her down, I'd reccomend rather slipping her a small human sleeping pill - if you're not willing to spend 80-100 dollars on her euthanasia. As said before, keep her warm, but in such a condition, she may pass soon. I am sorry.
  • Anonymous - 2011-10-02
    Thank you for your advice. Yes, I think she will soon too.

I recently had my favorite mouse pass away from a tumor. No less than a week has passed, and now her sister is acting strangely. They were never close, the living one would always exclude my favorite from their activities since I keep multiple. She had been fine these past few days, eating and running as normal, but today when I went to play with her I found her shaking in her bedding. This is certainly not normal behavior for her. I picked her up to feel she is very very cold and had her eyes closed. After a moment she opened them, but she didn't seem to move at all. I'm a bit worried she has gotten sick as well, but I was also hoping it may just be the weather changing. She also hasn't eaten, which worries me along with the fact that I could hear them all last night chirping to each other - a common thing for my vocal mice, but odd none the less for it to be constant.

(I did clean out their cage extremely well once the sister passed.) My other mouse seems to take no heed and is quite well even though she's a year older than the others. I'm just wondering if this has happened to anybody else? I understand it may be mourning over the other sister, but it's extremely unlikely since she showed no signs of it after the death. I'm keeping a close eye on her right now, but any advice would be greatly appreciated.

    I used to have three mice and one of them got put to sleep recently because she was bleeding badly and she had a bad wound (not from a tumour, but another one of my mice has a tumour so I think she'll die too soon.) My two mice looked for her for a few days and messed up the sawdust in looking for her. I've had experience. My mice would always take care of her though while she was alive. She might have got sick: In which case, you may want to consider taking her to the vet. Keep an eye on her and watch her closely to see how sick she is and unfortauntly, I know it's hard (because I had a rabbit and a mouse put down before) you may want to consider taking her to the vet to put her down if she's in pain and suffering and there's nothing you can do for her. I do hope you don't have to though, and she'll get better. Advice from your vet would be good: I hope she gets better soon!

    Thank you for your comments, guys. I'm sad to say that she actually passed away the day after I posted this - but I do thank you for your advice. I am now using it on a much older mouse of mine - Cleo - who is about three years old now. She's eating healthy still, but she has also developed a tumor on her leg, though it doesn't appear as bad as her prior companions. I've been keeping a good eye on her and feeding her well in hopes of making her feel better as the tumor didn't seem to alter her personality. I trained her to climb to the top of her cage in response for treats, but now the tumor is so large that it is somewhat preventing her from walking with her left leg. It is about half the size of her, and though once again I cannot see any signs of pain, I am still worried. I'm watching her eat now, and she's been fine all alone, but I also noticed her not being able to climb or run as much as she had done before. I'm suspecting her time is coming, but I'm continuing on my path to giving her the best life possible. Once again, I thank you for your comments.

I have a mouse named Oreo. She is about 4 months old. She has been fine until today. We woke up to her having a huge bump on her chest this morning. Has this happened to anyone's mouse before? Please help and let me know. I don't know what to do. It's my daughter's mouse.

    I have had several mice, Mus musculus, who get lumps and bumps on them as they get older. It can be fairly common, and mice are known to get cancer, most generally in their mammary glands. If it occurred overnight, she may just have some type of infection and the lump will go away. Make sure her cage is not where any drafts are and that her bedding is not damp and is kept clean. Give her fresh food and water daily in clean dishes. Also, keep an eye on her general behavior and condition and take note if any other symptoms occur that could indicate she has some other problem. At this point, I would just make sure she is kept clean and comfortable. You may want to read through the Ailments and Treatments Section on Animal-World's site for more information on what you can do.

    Thank you for the information.
  • Imogen - 2011-09-27
    My mouse Molly had just the same thing happen to her. She has a large lump on her too and I'm worried about it. It's probably a tumor. Is Oreo eating, active and pooping ok? If she is, why worry? But if she's not and she seems really ill and unhappy (I know it's hard, I had a mouse put to sleep) you may want to end her suffering by putting her to sleep in a harmless way. But I hope his doesn't have to happen. Usually they're fatty tumours. Cancerous tumours apparently grow larger and larger and more painful for the mouse as time goes on. But why worry now if she seems ok? Is she shivering? If she seems cold wrap her in a towel and put her to your body so she warms up. I wish you all the best of luck, and for Oreo. Keep an eye on your mouse and just enjoy your time you have with your mouse. I hope my advice helps you. Best wishes!

Hello, I have a 1 year old mouse named Maxwell. Just yesterday he began walking around in circles (not very fast, but he's constantly walking in circles now) and not acting himself. He is still eating and drinking normally, although he also developed a hunch on his back up around his neck area. I don't know if this is life threatening or if there is anything I can do. Does anyone know what is going on? And how I may be able to fix the problem?

    Doesn't sound real good but I don't think - based on this seeming to occur frequently in other mice/rats that anything can be done. Whether fatty tumor, or tumor - vet probably can't really do anything to insure postivie result. If he is eating and drinking normally, then probably not ill but probably not real comfortable. Everything ages differently. I am sorry.
  • Imogen - 2011-09-24
    How old is Maxwell? If he's still eating and drinking normally he can't be in much pain. And as long as he is still active. Maybe you should see a vet because he doesn't sound so good though. There might not be anything you can do for him. I am sorry. Just keep him comfortable and warm and keep an eye on him. I hope he's ok and I wish you and him the best of luck.

My mouse Jerry, is only young. I've had her about a month and a half now. A while ago she got a hard lump on her arm that keeps growing, I took her to the vet, he said it COULD be cancer but wasn't certain. He said you can either put her to sleep or get an operation done to remove the lump but it is 50 50 chance she survives because of the anesthetic. Please help me, I really can't stand losing her, and it looks such a struggle to walk with it. I worry everyday about her now, but I'm worried if I get it removed that she will die before she wakes up... is there much chance of her dying from it...

    I don't believe there is anything you can do. Chances are the surgery would cause his death and if it is cancer you can't just correct normally via surgery anyway. If he is eating and pooping and active, then although the leg is hard to move, he is probably not in a lot of pain. If he is not eating, and not active, he is in pain and you can have him put to sleep or just keep him warm and comfortable. Because a little fella has a lifespan of x years doesn't mean they will. Some go younger and some are older. I am sorry and know that this is hard for you but surgery seems an expensive option and I doub it would work even if the little one survives.
  • Imogen - 2011-09-24
    I'm so sorry. I think she probably won't survive if you give her the operation. Is she active and still eating and pooping? Or isn't she active and not eating and drinking? I've had a mouse been put to sleep before. I know how you'll feel if you have to. It's very upsetting: but if your mouse is in loads of pain and suffering, it'd be the best thing to do. I know it's very hard for you. I have a mouse with a tumour at the moment and I'm very worried about her too. I wish you and your mouse all the best of luck.

I got a mouse around 3 weeks ago(whiskie), not every old either. Then I got another one about a week ago (scotch). Whiskie died in his sleep and I don't know what from , now scotch is really sick. There are like little nits on him. He is very weak and he has a hunch on his back. I don't think he will make it though tonight. But if he does what can you do?
I love them sooooo much, it kill me.

    I'm very sorry but I think your mouse will die soon. If it's in a lot of pain and suffering, you might want to consider putting it to sleep. It's hard, but maybe the best thing for your mouse if it's not active and eating anymore. I hope you won't have to though, and I wish you and your mouse the best of luck. I had one mouse put to sleep before because of a skin condition :(

My mouse has lice or mites. I've sprayed lice/mite spray for birds on her 3 different times now but she still seems to have them. Shouldn't the spray kill them?

    Mites are species secific. In other words, mice would have mouse mites, dogs would have dog mites etc. Possibly a bird mite spray would not harm or kill a mouse mite. I would look for something that is for mice mites.
  • Claire - 2011-08-30
    I would take care of that as soon as possible - get a specific mice louse killing spray. I had four mice die of these lice, so I advise getting them taken care of quickly. (If you bought these mice as pets from a large company pet store, such as Petco, you may want to consult the shop keepers.) I had bought my mice there as pets, but was not told they were feeder mice. (Something I find rather disgusting - to feed live.) These mice are usually not well taken care of and can commonly have lice. It's a very inhumane living environment there, and I advise you complain immediately. If you did not purchase your mice from such a store, once again you should get a specific mice louse killer. These pests can be dangerous, and quite shocking when they get onto your skin. (They won't hurt you, but it's quite gross.)
    Good luck!
  • Imogen - 2011-08-30
    You might want to consider taking your mouse to the vet, or getting advice from them. Do you definately know it's mites or lice? It could be another thing. I'm not sure though. I hope she's ok
