any smart ideas? my cat has taken to jumping up onto the kitchen worktops whenever my back is turned. he NEVER does it when I am in the room because he knows he shouldn't 
unfortunately our kitchen doesn't have a door either, so it isn't as simple as shutting him out.
we're keeping the worktops as clear as possible, so it isn't that he is regularly finding food or anything up there either. and he gets fed plenty! plus catches wildlife to supplement his diet. nice.
is there anything i can do???
