I love my robo hamster and shes just too young to die. I just noticed she has lost the fur on her lower back above her butt. Also her skin is all scabby. I really cant be spending money on a vet. What are some treatments I can do ? She also shares a cage with another robo hamster, that one seems fine but I want to know if I should separate them, just in case? I looked up wet tail and I dont think its that. Please help. – Sandy
