• Aluminum foil: Cats are averse to the sound and texture of aluminum foil, so you can use it to cover the borders of counters to discourage them from jumping. My cats usually get the message after a couple attempts.
• Double-sided tape: Same concept as the aluminum foil. Put unpleasant sticky tape on surfaces you don't want cats to touch. (This works for upholstery, too.)
• Blender Defender: One cat owner rigged an elaborate motion-detecting blender to teach his pet a lesson! No, I wouldn't do this, but I admit it's amusing.
Finally, of course, it's important to keep surfaces free of tempting food and dishes.
