Suitable for some cats
My version is old, with the third cat now. The first one loved balls, but wasn’t interested in this track. The second didn’t care about balls at all. The current one absolutely loves it. The flashy ball disappeared somewhere years ago, but the other original is still around. The kitten really got interested when I replaced the original ball with a light ping pong ball. Now there are two balls on the track, which seems to be even more fun since they sometimes bump into each other.
