Potty-training a baby? Feh. Try potty-training a rat.

The woman in this video (who, according to the self-written description on YouTube, is diabolically sensitive about anyone questioning her bathroom's cleanliness) managed to teach her hairless albino rat how to use a toilet whenever he has to, you know, make with the pellets.

And -- bonus -- no diapers! Take that, tiny humans.
