Trivia: Top Cat
- Hey, It's That Voice!: In the Mexican dubbed version ("Don Gato y su Pandilla"), "Benito Bodoque" (Benny the Ball) and "Cucho" (Choo-Choo) are both voiced by Jorge Arvizu, who is perhaps best known as the voice of "Pedro Picapiedra" (AKA: Fred Flintstone).
- "Don Gato" himself is voiced by Julio Lucena, who had also voiced "Pablo Mármol" (Barney Rubble).
- The Other Darrin: All of the original cast reprised their roles for "Top Cat and the Beverly Hills Cats" with the exceptions of Maurice Gosfield and Allan Jenkins, who had died in the interim. In the film, Avery Schreiber replaced Gosfield and John Stephenson (who did Fancy-Fancy's voice) did double duty as Dibble.
- Unintentional Period Piece: From it's sixties slang, to the running gag of Top Cat constantly using Officer Dibble's now obsolete police phone, the show can't really work outside of the 1960's. Hence why the series doesn't feel right when placed in a modern setting.
- What Could Have Been: It's rumored that the show was going to get a second season, but it was decided against due to Maurice Gosfield passing away and Hanna-Barbera not being able to find a replacement actor who could match his voice.
