ask him if it's crumbly. if it is, it totally looks like fungus to me. i'd probably go to the vet. there are otc medicines you can buy but they're for people so i don't know if you can use them on cats. horses get the same thing, it's like dry rot inside the hoof, but i can't remember what it's called.
