Hamster-Powered Paper Shredder

Another great animal-human synergy in the spirit of the goldfish tank/deep-fryer, except more sanitary.

You shred your sensitive documents without the trouble of pushing a button. And your pet hamster gets exercise and fresh bedding dumped into his cage. It’s a win-win.

Only downside, imagine the Feds are knocking down your door and you’ve got 90 seconds to shred your shoebox full of incriminating papers. In this dire moment of need are you going to count on some glorified rat to put down his food pellet and give a damn about helping you out?
