For an actual helpful answer, my best suggestion is double sided tape. Cats hate shit sticking to their paws. Eventually they'll probably learn not jump up there

Contrary to popular belief you can train a cat, but most people let their cats train them instead

Seriously, the amount of misbehaving cats I've met in my life all comes from owners that don't know how to properly train their pets, and think bad behavior is cute. You can easily train and condition cats to stop certain behaviors, it's just that a lot of pet owners, especially ones with cats are too afraid to even start the process.
