Is there something wrong with my sisters hamster?
Sylvia is a Golden syrian hamster. My sister has had her since July/August. Recently Sylvia has had a wet patch around her tail area. It is there, then the next day it has gone. By the end of the day the wet patch is back. It keeps drying then becoming wet again then drying and so on. We think it may be that maybe her water bottle dripped a little bit and she sat in a wet patch but I think I need the opinion of someone who knows more about the health of hamsters.
