CatDog - Season 3 Episode 17 Cat Gone Bad

Cat suffers an identity crisis when a gang of beatnik alley-cats set up shop near the CatDog house. Seduced by their bongo music, he trades in his normal, prissy, finicky self to become the cool, hep "Scat Cat". His new alter-ego is much more laid back than the old Cat. In fact, he's so cool with everything he does that he refuses to clean the house, or even pay the bills. It's up to Dog to get the old Cat back that he once knew.
