The name of the cat in Breakfast at Tiffany’s. He hangs around the main character Holly Golightly throughout the movie. She refuses to give “cat” a name because she says he doesn’t belong to anyone.

A little excerpt from the script, right after the cat screeches

Paul AKA Fred: Is he alright? Holly: Sure. Sure, He’s O.K. aren’t you, cat? Poor old cat. Poor slob. Poor slob without a name. I don’t have the right to give him one. We don’t belong to each other. We just took up one day. I don’t want to own anything.

So she just calls him “cat” throughout the movie.
