I know cats shouldn't drink milk but my kitten took a few licks out of my empty cup that still had a little at the bottom. Will he be okay? So far he seems fine but he has never had milk before, just cat milk.
He should be fine. It isn't that milk is poisonous, it's that most cats are lactose intolerance. I think the intolerance becomes more common as they get older. The most that will happen is a little diarrhea.
