So the guy in this video took the idea of a hamster wheel, sized it up, added a reward system, and put his cat in it. The video is of his cat running in the cat wheel and every once in awhile after the wheel goes around enough a piece of food is released and falls down a tube and into the cat wheel. It didn't seem like the cat was stopping to eat the food though so I'm not sure what the cat's reason for running in the cat wheel is. Perhaps the cat treat or whatever it is doesn't fall out very often. Additionally there is a stick which hits top of the wheel and creates a tap tap sound as the wheel goes around.
