Couple things that have worked ok for me. We have a "can of air" with a motion sensor. If they jump up it beeps and shoots air at them. Usually under $50. not cheap - but it's saving my plants!. Also you can put double sided sticky tape on the counter. They don't like it on their paws. Just remember to put a few varying strips so they don't just jump past it. If neither works for you, as rpcathouse said, give them their own section!
