try turned over carpet protectors(clear plastic with pointy nubs on the bottom) ...I've walked on it, it hurts!

oouch!!!

how does the foil method work? this is a new one for me. thanks.

I've tried the tin foil method to keep the cat off of the kitchen counters and table. She won't even think about jumping up when she sees the foil there. Just lay strips or pieces on whatever surface you don't want the cat on. They hate walking on it for some reason. Try putting it on the floor in front of her first, to see how she'll respond and if she stays away from it.
