Mice/Mouse injured himself?


This morning while I was feeding our mice I noticed one of them was acting sluggish. He's moving very slowly and with a limp. Ive examined his feet and they look fine so I'm thinking he may have hurt his back while running on the wheel.
Also his eyes seem to be half opened and while he sniffs around for food and even went and sit on top of it he seemed unable to find it.
Any ideas what the problem may be? Should we take him to a vet or wait to see if he gets better?
Thanks for the help.

Hi Akira,

It does not have to be a back injury, necessarily - just like in people, it is possible to sprain or pull a muscle or injure a joint anywhere along the limb he is favoring.  Depending on the severity of the injury, how much internal swelling he experiences, and how it heals, he may get better on his own, but it does sound like he is in pain.  A mouse that is hurting will move slower and pay less attention to food and water (he may be able to find it, but not feel well enough to actually eat).

It would definitely be beneficial to visit a vet who works with mice if you can.  It sounds like he is in significant pain, and they will be able to help by identifying how serious it is and offering pain management until it can heal.

Best of luck, and hope he feels better soon!

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!
