Spiffy, a Neat Freak cat voiced by Frank Nelson, served as the animal Felix Unger, while the character of Oscar Madison became Fleabag, an unkempt dog voiced by Paul Winchell. As in the play, film and live-action sitcom, most of the comedy came from personality clashes between Spiffy and Fleabag, but turned Up to Eleven to take advantage of the animated format.
