I posted this in a thread that Richard started about cat tricks, but thought Pippin deserved his own thread.
This maneuver is called a Pip Flip and is something he has done since kitten-hood. He does it when everyone is excited and playing or when he wants us to stop talking and come pay attention to him. You can hear him banging on the walls.
It is hard to get on film because he stops when he knows you're looking.

Anyway, Enjoy!
