Cat on Furniture help please

Thanks all, I moved the family out and back in again and then the lecture option came up. No more jumping on counters and tables (added deco). My real life cats know that they stay off tables and counters, they are allowed on their catrun, couches and beds and that's it. They only get kitty food so no human food. I get many suprised visitors that can't believe if I put a plate of food down on a counter or even the couch next to me they won't go for it even if we leave the room. Well trained LOL, well I think since they don't eat human food why want it then :)
