Max has been scratching at his ear. When I adopted him, he had a bad case of ear mites. He had to be treated three times. He is now 3 years old and every October during his vet visit, he has an ear infection. It starts in one year and then goes to the other. I am now an expert in giving cats ear drops. When he was a year old the vet said it was from the residue of ear mites. He can't still have ear mites, can he? He is an indoor kitty and never goes out. What would cause him to have continual ear infections? Is there any way I can tell if it is an infection on my own without taking him to the vet? Could it be just dry skin? I don't mind spending the money on a vet, it's just that it is so tramtic for him to leave his house.
