Heathcliff knows he is the best cat around! Never have we seen such self-confidence topped off with a heavy dose of vanity, cunning, ruthlessness, and a mischievous love of gags. He cruises and struts down the street and watch out any person, cat, or dog who gets in his way! Although he may terrorize the neighborhood, let an outsider try to push anyone around and he is a veritable tiger of defense. On the other side of town are The Catillac Cats, which typically revolve around leader Riff-Raff's get-rich-quick schemes or searches for food.
A kitten shows up in the neighborhood with an enormous case of hero worship for Heathcliff. However, he is so much like the object of his esteem that Heathcliff himself can hardly stand his new little shadow. Eventually, the kitten moves on and leaves Heathcliff alone.
When Cleo visits her cousin, LuluBelle, in the country and takes the Catillac Cats along, it's love at first sight for Mungo and LuluBelle. But the amorous boy-next-door, Orville, already has designs on LuluBelle and will stop at nothing to keep his new competition from edging in.

But to Heathcliff's dismay, the lion is a kind-hearted and gentle creature and not at all to Heathcliff's liking. The apes in the zoo make fun of the lion because he is so tame. Heathcliff gives the cowardly lion some pointers on being fierce and strong which helps the lion put those nasty apes in their place!
It's the Cats vs. sneaky Admiral Catsk in a race up the slopes of Mount Whoji next. Bears and mountain goats add to the surprises and fun up the trial; but the biggest surprise of all is Cleo waiting at the top of the mountain to toast the losers with champagne.
