I have a cat sitting on my lap. It has the power to lash out at any moment. It digs it claws into my knee to remind me.

A cat fight is superiour to a dog fight anyday. Cats get fucking pissed when they fight, and sometimes they leap into fit of hysteria.

Also, you can't gode two cats into fighting like you can with dogs or people. Cat's fight and there's nothing but a pitcher of water to do anything about it.
