Heathcliff the cat relies on fellow parrot and household pet Louie for help in everything from getting his paw out of a mousetrap to reminding him, "You forgot to breathe again, stupid!" One day, Heathcliff finds a written will and asks Louie to read it. The beleaguered parrot discovers that Heathcliff will inherit the estate. However, if something happens to him, then the parrot becomes next in line for the money. All good intentions are now down the drain as the wily parrot tries to destroy the unsuspecting cat, who's too stupid to realize it.
Louie the parrot tricking Heathcliff into sticking electric wires in his ears by saying it's a radio, only for Heathcliff to actually get radio transmissions through his ears (while Louie does the same thing and gets electrocuted)
Louie then tricks Heathcliff into walking along railroad tracks with a can over his head -- and Heathcliff derailing the train and somehow surviving.
The original closing titles are presumed to be lost, as the cartoon only exists with the 1957-59 Merrie Melodies closing titles.
