1950's Merrie Melodies offering The Hypo-Chondri-Cat is a hilarious but strange cartoon from animation legend Chuck Jones and the Termite Terrace crew. Wisecracking mouse duo Hubie and Bertie attempt to move into a cozy new home inhabited by the neurotic Claude Cat. Playing on Claude's hypochondriasis, Hubie and Bertie stage an elaborate ruse to convince the credulous Claude to vacate the house and head to "Cat Heaven".
It's weird (check out the surgery dream sequence), a little twisted, and borderline surreal—but it is funny. Probably not appropriate for really little kids, unless you want to answer endless questions about whether Claude's really dead or not. While the great Mel Blanc gets sole billing for the voice characterizations, he shares his duties with the equally great Stan Freberg, who voices Bertie the mouse ("Yeah yeah, sure sure").
The Hypo-Chondri-Cat is available in the Looney Tunes Golden Collection
