My cats can go anywhere they please, so yes, even in the kitchen. Cats are different from dogs, they'll do what they want anyway especially when your not there. If I'm cooking, I'll clean the worksurface down first, but as my cats don't go out and they are very clean (as all cats are!) I don't really think of it as a problem. I make sure there is never really food around in the kitchen, so they don't really go in there a lot, only for their dinner or for their biscuits or water.
