If your cat is rewarded for jumping on the counter, the behavior will continue. Keep your counters, table, and sink clear of food at all times. Buy several cheap plastic placemats and cover one side of them with double-sided tape. Keep the placemats on your counters and tables when they aren't in use. Cats don’t like sticky surfaces, so the goal is for your cat to jump up, feel a painless but uncomfortable sensation, and jump down. When weeks have passed without signs of the cat on the counters, remove one placemat every day until the counter is clear. If your cat’s cruising habit returns, put the mats back.
