I wish my cats would fight this silently! One of mine screams bloody murder when the other cat teases him. It's the cat equivalent of a little kid screaming "Mommy! Mommy!" when his brother picks on him.
Sometimes I'll be on the phone and they'll start fighting. The person on the other end will be like, "What in the holy hell is that noise?" and I have to a) yell at the cats to stop that racket, and b) shamefully explain what's going on to the caller.
