Iroh had a kitty get him where his nose meets his muzzle line at the very top. We tried to put some ointment on it but he licked it off and wouldn't stop messing with it, so rather than let it heal, he kept on licking. Now it's red and raw-- tiny patch of fur where the scratch was is pretty much gone, and he's still at it. I don't know what to do. It's definitely painful...he whines and rubs it against his pillow. I can't get him to stop and it's getting worse. Help?
