My cat is black and he’s got these little spots on his nose that I noticed several days ago and I dont know what it is or what to do. Plus he’s even losing hair near his forehead and ears and some on his mouth. I recently got him checked up in the vet and they said there were no ringworms or anything. Everything came up negative. So... idk. But i have noticed him constantly licking himself everywhere especially near his ears. Its as if he’s obsessed with grooming himself. Is there anything I can do to treat him from home?
