| We've had LOTS of small mammals! Hair loss is usually due to parasites (mites, mange, etc.) If it's mites, it usually gets real itchy around the face and neck. But since it on the back, I'm not sure...
Are you using cedar shavings? Some small animals are really sensitive to the cedar oil and it can be irritating. Use pine shavings or that recycled paper fluffy stuff instead.
Hair loss can also sometimes be caused by a vitamin deficiency. Try adding some small animal liquid vitamins in the water bottle. If you don't see an improvement soon, take the hamster to the vet! |
