I was going to suggest some citrus as well. My cat won't go on the bench (or anywhere near the kitchen) after I use the orange power surface cleaner. I don't really blame him though, it's one of my last resort surface cleaners and is rather potent. To keep next door's cats out from under our house and to stop them terrorising other next door's dog, we put lemon and grapefruit through the blender and put it down the side where they were causing trouble. We haven't heard a peep in the past week lol
