Buddi has developed a strange lump on the side of his head, just below his ear. He's scratched at it and it definitely has puss coming out of it. It looks scabbed over on the top of it, but it wasn't there yesterday when I brought him out. I know of some animal hospitals around me, but don't know if any of them can treat dwarf hamsters. Also, my mom doesn't want me spending much money on vet bills for a hamster. When I try to take a look at him he tries to run away, and I put on gloves just to make sure he can't bite me when I finally catch him. What should I do?
