I have a ragdoll cat that I recently aquired from someone that didn't care for him properly. I treat him monthly for fleas...but his entire back has hotspots. (All the way down his back..from his neck to his tail) I've put cream on it like the vet advised, but it's been two months and he's not any better. I hate to take him back if they're going to tell me the same thing. Does anyone have any advice? Any home remedies?? Any is appriciated!!!
