Teepao Magic Roller Ball Toy, Automatic Roller Ball Magic Ball Dog Cat Pet Toy (1 Rolling Ball 4 Color Ball Cover)

The rolling ball is surprisingly effective at getting out of the corners and crevices it rolls into. However, the fabric covers included in the package were practically useless. When zipped into one of the fabric covers, the ball is no longer able to roll on my hardwood floors. Instead, it sits in place a sort of wiggles. Additionally, the fabric covers shed tons of lint and bits of fabric. But the ball is pretty entertaining on its own. I got it as a cat toy, and it works for that purpose.
