I got one by accident. I bought a different toy off e-bay and the supplier sent a panic mouse instead. Got it for much cheaper than normal and wasn't overly impressed. Cleveland will take notions of playing with it but would rather you dangled a bit of ribbon for him. I think Pete got the most amusement from it when I turned it up full and got batted with the mouse several times before I could turn it off. I wouldn't spend the money on it.
There are many intelligent species in the universe. They are all owned by cats!
