Hi,

I got two male roborovsky dwarf hamsters about two months ago, and they live in the same cage. They eat the same food, use the same bedding, etc. However, one of them has lost all of his fur on his butt. The skin looks red, irritated, and possibly scabbed. I am wondering what could be going on, since he is moving around fine and eating well. He also gets along fine with the other hamster. I have only ever seen them playing. THey have never fought or hurt each other so I don't see a reason for that. What could it be and do you think I should go see a vet?

Hi Alice

Yes I do think you should, the skin sounds sore and uncomfortable so even though he is not showing other signs of illness you should get this checked by a vet to identify the problem. Mites or skin infection are equally possible and the other hamster may get the problem too if you wait.
