Q: I purchased this with the hopes that it would be an enjoyable experience for my little cat. It turned out to be about 10 minutes of fun and then went right back in it's box. My cat likes toys too, but he is not a crazy mouse hunter. But we did try to entice him around once or twice more so he might want this. The "mouse" only has one small section on his back.
