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.
When you were a kid it was kind of like a cheap Garfield wasn't it? That's not to say it was bad, but the Cadillac Cats didn't hold much of a candle to US Acres and, in either case both the Heathcliff and Garfield segments were a little dull in comparison to the sub-shows.
In any case, it's not really a nostalgia 10 stars, it is funny, it was a pleasure to watch, and the opening theme did get stuck in your head. So, it did it's job.
