Heir-Conditioned (1955)

Continuity mistake: When Elmer opens the door to the hungry cats, you can see that there is only a handle on the door, but when one of the cats demands more money, Elmer slams the door and the handle now has a lock with it.

Trivia: When we see a cat looking through the dustbins at the beginning of the cartoon, there is a newspaper on the ground that has "Foster" on the front page - a reference to the Warner Brothers story writer Warren Foster.
