I want to claim that I finally outlasted Smokey on his wheel but the truth is Hiro entered the room and that is why Smokey got off his wheel. Usually he will just keep running and running until I get tired. I have been told by ZiggyDoo that they discourage humans from powering the wheel as a safety measure so do not try this at home:). That said, I think this is a great commercial for Ferris Cat Wheels from ZiggyDoo. So sturdy and the only noise is my hands as they hit the wheel.
