Heathcliff and the Catillac Cats - Season 1 - Eps 20: Swamp Fever
Wordsworth is convinced he has a rare cat disease which Riff Raff read about in the paper, so the gang take him to a cat witch-doctor who tells them the only cure is an alligator hair. The cats risk their lives in a swamp before returning to tell the doc that alligators don't have hair. No matter, Wordsworth seems better.
