Cats don't need exercise. They're perfect just the way they are. But for some reason these little guys can't help but be totally enthralled with the treadmill. And it makes sense if you think about it. While we might be all motivated, going for the run of our life, getting healthy, getting in shape and buff, to a cat the treadmill is a totally foreign contraption. Humans, on a moving walkway inside the house, huffing and puffing and fighting to walk in place.

So seeing it from Snowball and Pepper's perspectives, it makes complete sense that they would stare and poke and prod with their little furry mittenesque hands. They're simply looking out for our well being.
