Hmmm...this guy's too slow...Hurry up you nut or I'll bite you!
Get the ball you big blundering buffoon!!! You should just let this kitty play, I am sure I'll be able to do better.
Urghhhh!!! The game has gone to the dogs!!! You should just leave it to us cats, we know what to do with balls. We roll them, we pass them around, we bite them, and scratch them, and bite them, and scratch them, and bite them...gimme a ball!!!
