It's an interesting premise for a toy -- it has a vibrating gyrator in the middle which turns on randomly for random durations. This then causes the ball to vibrate and roll around the floor. It really needs to be on a hardwood floor to move, though -- when I put it on their dog bed, it vibrates but then doesn't move anywhere. I tried a few times to get my four dogs to interact this this ball toy, but they are clearly not interested.
