Well, I had to clean a Rocky's cage, sorry I couldn't get a video up. Anyways, I got Rocky a green hamster ball at my local pet store and I really was curious to see how he reacted. At first he kind of sat there, then I placed his chew toy in front of him and he leaned over to get it so he moved the ball. Once he realized he could move he did it more. He is still messing around with it but I think he will figure it out.
