One Hell of a Way to Exercise Beef

There is a video I want you to see, but you'll have to watch a short one (and a Butterfingers commercial) first.

I can't decide if this is an experiment in Pavlovian response (although I'm not sure what the reward is) or a new way to create leaner beef. Go here and you'll see a 16-second kitty video and then the most amazing thing I've seen in a while to the tune of the TV western show Rawhide.
