Frank Thompson as Admetus

A character probably created for the 1998 film (in other productions, Plato and Admetus are the same character), a tan, yellow, and black tom around Alonzo's age. His one discernible character trait, on the rare occasion when the camera captures him, seems to be to grin slightly inanely at whoever or whatever is being sung about at the moment. Admetus is played by Frank Thompson, who also plays the Rumpus Cat, in the 1998 film.
