Mice/fighting mice


Hello I recently got a female mouse to join my other girls one mouse has started fighting so have no separated her from the group my mouse that got caught up in the attack is now very cold and in a haunch position not very active refusing food and water could it be that she's in pain

Hi Sarah,

Yes, it sounds very much like the mouse that is hunching is in pain.  Do you have a local vet who works with pocket pets like mice that can see her as soon as possible?  Keep the injured mouse separate from the others for the time being so she can heal and so you can observe her as closely as possible.

You can place a heating pad on its lowest "warm" setting underneath her enclosure to keep her from chilling, but if she is losing body heat, something quite serious is wrong.  Check her all over - do you see any scabs, bumps, lumps, missing fur, or broken skin that can help you figure out in what way she is injured?

Her best bet is to see a vet as fast as is possible.  Please let me know if there is anything else I can do.

Best of luck,

I can answer questions regarding mice as pets, mouse behavior, color and coat genetics, breeding techniques, and general health questions. I can help with caging and setup, nutrition, social issues, and what to do in most mouse emergencies (such as unplanned litters, injuries, fighting, etc.). I can also assist with questions pertaining to orphaned mouse pups, weaning litters, and questions of mating and birthing. I cannot answer questions about exotic or wild varieties of mice such as spiny or pygmy mice. *****FOR EMERGENCIES, anything requiring immediate medical intervention, PLEASE take your mouse to a professional veterinarian or wildlife rehabilitator who works with mice as soon as possible!

I have enjoyed the companionship of mice nonstop since 2004, and spent a year caring for them in a lab where I learned a great deal about their breeding, social needs, and health. I spent a few years breeding them, specifically working with albinos, marked mice, angora mice, and satins. My education never stopped - I am learning something new every day from current and well-established research thanks to the wonderful folks at the Jackson Laboratory, as well as from my wonderful mousey friends online. I also love learning from my terrific questioners here on AllExperts - you folks keep my passion for these amazing animals alive and well!
