I have a male indoor cat and he's about a year old and He isn't neutered . lately hes been scratching the back of his neck till the point its creating bald spots and bleeding, but he won't stop at that he continues to scratch until I stop him. I've been cleaning out the wounds and putting polysporn and bandages over it trying to stop him from scratching it even though its only stopping the contact of his nails. He's also got like black kinda clumpy looking stuff on his chin. I just changed his food dishes from plastic to glass in case it has anything To do with it. We recently moved a guy in and he owns a cat who is very aggressive and hisses at him and bullies him a lot.hes also been peeing out of the litter box every Now and then. I can't afford a vet so I'm a little worried and want to see if I can fix it before it gets to bad and have to resort to a vet. ( PS. I feel like the peeing is just him not being neutered but I need reasurrance)
