You need to be firm with him about it. Don't just brush it off. Tell him this arrangement will last for a while,but then he will need to buy his own cat food once they grow up a little more. If he doesn't agree to that, you might have to tell him he needs to find a new home for his cats or a new home. It's very important to lay down the rules, especially since it is a shared living space. If you aren't firm with him he will just keep doing things that bother you.
