Hi, can anyone help? I found the sweetest stray cat. It was a long haired one, but the rear legs are not completely bald, but the hair is thinning. Everything I have read about mange, it is always on the front of the cat and it itches. I haven't seen this one scratch and it is losing hair on the rear legs. It is so scrawny, I've been feeding it and wormed it, and flea treated it.
