I took in a cat months ago he is about one year or so vet looked at him says he has cat acne. Okay fine. He does scratch now and then and now he scratched on the outside area near his ear it has scabbed but now a bit bloody due to scab. Is there anything I can put on it to help it along. or should I let it heal itself?? he can be obsessive with scratching and cleaning, everyday is different. He eats california natural dry and some fancy feast. tried other foods but no like. I hope he calms down its usually mornings he crazy and does jump on my older 10 year old cat but calms down eventually??
