The Bullet Cat was a species of Cat that hailed from an Undefined Multiverse, and a particularly curious one.
The Bullet Cat lacked legs, and compensated for this by levitating. It was capable of propelling itself at incredible speed, using this as an attack, occasionally combining it with it's sharp teeth.
It was also more durable than a typical cat, being able to survive repeated battering of it's opponents with little effect.
The Cat on a Keyboard in Space was at one point called upon to deal with an infestation of them.
