Watch these two cats trying to figure out their human’s treadmill. What is this stupid thing, anyway? It doesn’t respond to getting smacked: can it still be alive?
By the way, I know a human who, if he ever put his hand on an active treadmill, as these cats do, would be guaranteed, you could bet the house on it, to get his fingers caught in the mechanism and mashed to a pulp. The cats are smart enough to avoid that.
