I found this link through Boing Boing about a man whose cat lost the use of his rear legs in a traffic accident. The owner's solution: build a robotic platform and teach the cat to drive it around the house.
Thanks to Todd for pointing out the Boing Boing follow up indicating this one is a hoax as well. At least I wasn’t the only one to fall for it this time. Cory Doctorow was taken in too! The video is still pretty cute though.
