Yes, my Coco Puff jumps up on the counter sometimes when I'm preparing meals, especially if he hears me tearing romaine lettuce. Look out! I toss him back on the floor w/a stern warning and if he does it again, he goes to the basement. Perfect world, I'd love to have all indoor/outdoor cats but it just isn't safe here. However, you have to do whatever works for you and your circumstances. Have you thought of microchipping?
