I don't believe in demonic possession. I also would never bother to post a clip just to scream "FAKE!" That said, I have no idea what is up with this cat walking backwards on its hind legs. Sending the video's Japanese description through Google translate only adds to the mystery: "When it is not helped when we want to eat because I wanted to eat, and Momotaro to move back to stand for some reason." The main thing I get from that is that Google's Japanese to English translation could use a little tweaking. If nothing else, it seems like Momotaro isn't suffering from a neurological condition or possessed by demons. He's just weird.
