This is Tuxedo.

He is the King, the oldest, the fastest and the leanest.

The snottiest: He only eats Boarshead meat.

The fastest: a.k.a. Speed.

He loves to smack the others around, but would never hurt a person.

Tuxedo is the Fastest cat. He is in the best shape out of them all and knows it. He is black and white, hence the name "Tuxedo." The black fur is on his back and the white is on his tummy and face.

He is by far the smartest. With Snickers, he has ripped open bags of treats and food in unreachable areas when left home alone.
