Bionic Cat Can Drive Himself to the LitterBox, But Can't Use It

I'm a bit confused. Elvis the cat has lost his ability to walk. Therefore, his enterprising owner built a robotic extension for him to drive around in that looks like the love-child of a cardboard box and the Mars Rover. After watching the little guy drive around, I'm not sure it's an improvement. Sure, he can go places, but he can't actually do anything once he gets there because, well, he's encased in a cardboard box, for cryin' out loud!

Still, kudos to the owner for designing a control scheme that can be understood by a cat. Maybe there's hope for the senior citizens of the world.
