- Acceptable Targets: The British. If you see a character talking with a British accent, chances are he or she will be rich, snobby, a bad guy or some combination of the three.
- Adaptation Displacement: The animated series is more well-remembered than the comic strip.
- Cant Un Hear It: What did you expect from Mel Blanc voicing Heathcliff?
- "Common Knowledge": Many people who grew with the series would swear the Catillac Cats were a sort of rival gang to Heathcliff, despite the two actually belonged to different stories inside the show and only very sporadically interacted with each other (the segment's respective main characters, Heathcliff and Riff-Raff, actually never appeared together outside of the ending credits and some promotional art). Part of the fault goes to the fact that, although the Cats are as memorable as Heathcliff himself, the show's title implied it was exclusively about his adventures or at least about all together, thus implying they were logically part of his story. Fault also goes to the aforementioned shared closing credits, where Heathcliff appeared antagonizing Riff-Raff by stealing his hat.
- Designated Hero: Heathcliff can come off as this, sometimes.
- Designated Villains: Hector, Wordsworth, and Mungo whenever they appear in the Heathcliff segments.
- Ear Worm: The doo-wop style theme tune is quite insidiously catchy.
- Ensemble Dark Horse: The Catillac Cats. When this show aired, it was always about Heathcliff: only his segments were acknowledged in promos and commercial bumpers (at least on Fox Family), and whenever the Catillac Cats were advertised, they were treated as secondary characters. However, many fans of this show will agree that The Catillac Cats were much more interesting and entertaining than Heathclif.
- Germans Love David Hasselhoff: Given that the show was partially made in France, the French got the entire show on DVD years before America because of this trope. Also, there were some toy figurines of The Catillac Cats produced in France. Even a toy Cadillac car that could be changed into a hovercraft, and trailer, just like in the show. If you're lucky enough you can find these up for auction on eBay.
- Hilarious in Hindsight:
- Iggy's redesign bears a strong resemblance to Mac.
- Dixie (the athletic cat whom Mungo falls for) in the episode "The Games of Love" looks very similar to Minerva Mink, who wouldn't exist for another nine years.
- The Catillac Cats episode "Time Warped", almost feels like a parody to Back to the Future Part III, what with the cats sent back in time to the Old West, the Cadillac filling in as the De Lorean, and having to use a train to get back to the present time. However the episode was made at least three years before BTTF III hit theaters.
- Nightmare Fuel: From "Kitten Around", this image◊ of a super-pissed off Cleo when she threatens Roxanne.
- That is pretty scary!
- in the cartoon "Monstro vs Wolf hound" Monstro had a really scary close up.
- That is pretty scary!
- Sequel Displacement: It's also more well-remembered than the Ruby-Spears series.
- They Wasted a Perfectly Good Plot: Even if the Catillac Cats, as repeated above, were more popular than Heathcliff, that the latter and Riff-Raff never interacted fully in the series is thought to be a pity by some. The Slobs vs. Snobs contrast of their respective characterizations in the series was so evident that it seemed intuitive for them to mix together and feature funny moments.
YMMV / Heathcliff and the Catillac Cats
