American Bobtail Cat

While the breed is still developing, breeders say that Bobtails are playful, energetic, and friendly, and possess an uncanny intelligence for Houdini-type escapes from closed rooms and fastened cages. Very people-oriented, they are not above demanding human attention by meowing or commandeering available laps.

On the cat activity scale (with, perhaps, the Persian as a serene '1' and the Abyssinian as an animated '10'), the Bobtail rates a 7 or 8 ' fun-loving and frisky but not overactive.
