My cats really love the snack dispenser ball that I got for them. You have to roll the ball to get the snacks. My oldest cat, Callie, at the center, was the first to figure it out. Now anytime we fill it up, they all come running. Callie plays with it and the others stand around waiting to see if she misses any treats as they come out. She plays with it only long enough to get all the treats and then walks away.
