Is that little guy chasing his tail?? Or does he just roll around inside that house?? That is so funny. I have a orange tabby male that does something like that but he chases his tail. I could have swore that he was suppose to grow out of that at like 6 months old. Or at least that is was my behavior book tells me????? That is great you should get that on video and submit it to Americas Funniest Animals on Animal Planet.
