Muriel and Floyd are the tertiary antagonists of "The Secret of NIMH 2: Timmy to the Rescue". Whether they are married or not is unknown. Of course, only one goes in the "Singing Villains" category, that being Muriel. They are two stray cats who always want to eat Timmy. Their defeat is always met by them falling in the elevator, first on the cage's roof, and then just not at all. They are respectively voiced by Andrea Martin and the late Harvey Kornman.
