We have 4 cats. Three of them are older (14, 13, 12), and the other just turned three years old. Our two boys, Wuzzie our oldest, and our youngest, Carter, love to play Red Dot. That is, we take one of those light pointers and shine it across the floor and up the walls. While Wuzzie seems to lose interest somewhat quickly, realizing it's just a light, Carter could play forever. We run the light up the wall, and he runs and basically climbs and jumps up the wall. It's very cute to watch them play. The funniest thing about it, too, is that my father-in-law picked it up for them in Japan while on a business trip, realizing they'd probably have fun with it. He used it at a meeting then gave it to us for them. (I thought that was sweet.) My girls aren't as into toys. But they do sometimes find something on the floor and bat it around for a few minutes, which is fun to watch too.
