Mouse losing fur! HELP?

shes the leader, bout 5 months old. the others are fine, somtimes theres a skawabble - nothing too unpromising only one bloodied ear to another mouse but shes fien now. This mouse has lost fur around her front legs, her stomach where her bum is is completly balled now and her fur is thinning around her rear legs. any help?!
Omg, you might be loosing her.. It's ok you might have another couple in your rear yard to keep as pets :).
If you're really concerned and attached, I would cart her to the vet. Honestly, this happened to my rat when she was pregnant. Apparently it had something to do beside nesting or whatever. Just a possibility...
Answers:    I had a mouse that lost fur, but in her valise it was because she over-groomed due to boredom and the fact that my roommate neglected her (hence she came into my care). The one and only thing I can think of is that she might have some bad health, or that she just over-grooms for no reason. If you have other mice, it shouldn't be because of boredom...but I really don't know. Good luck!
You should completely remove any fur from your mouse. It can clog it up and prevent your cursor from moving properly.
It could be a parasite. I work in a pet store, and we have a robo dwarf hamster with the same symptoms. The vet gave her an oral medication once per week for 4 weeks and her fur grew rear as normal.
If no exercise globe, how should I exercise my kids G Pig?   Should you buy a pen and other stuff first or buy it together when you buy a hamster?   Is it better to receive one Robo hamster or two?   My feminine guinea pig have white stuff around...?
