Yoga Kitty 
I don't understand yoga, nor do I try it, but this website makes yoga awesome. It's called YogaKitty and it's all about doing yoga with your feline companion, or more accurately, it's all about "Purr-fect Yoga." Check out the videos for the ultimate in awesomeness. For even more fun, watch the videos as dubbed in Japanese. It's not serious, so don't go expecting to do downward facing dog with Mr. Bigglesworth, but do go for some great videos.
