I have along haired cat who is always cleaning himself, he does it so often he's licking himself raw. I've tried putting some oil in his food ( heard it's good for dry skin) I heard yeast was good for dry skin as well and tried that to. I check him regularly and have only seen one flea, plus he's not itching he's licking. I feel so bad because of the raw spots, I've thought about shaving him to see if that will help. Any suggestions?
