* BreakthroughHit: The Oscar win brought both Nick Park and Aardman to the attention of American studios interested in an InternationalCoProduction, though the studio had the clout to turn down offers for a few more years until they were ready.
* CowboyBebopAtHisComputer: Due to the film being created by Creator/NickPark and, therefore, sporting his design style, some American viewers viewing the original short (or parts thereof) mistook it for an existing or forthcoming ''WesternAnimation/WallaceAndGromit'' short where said characters visit the zoo.
* DevelopmentGag: Some little quirks about the interviewees made it into the animations. One interviewee was a man who was always getting called away in the middle of his sessions, so the animators made him a greyhound whose race always begins mid-interview. Another was a woman who was vision-impaired, so she was turned into a seeing-eye dog.
* DuelingMovies: Oddly enough, with Creator/NickPark's other short, ''WesternAnimation/AGrandDayOut'', which were both up for a 1990 UsefulNotes/AcademyAward for "Best Animated Short." This one won. And they were ''his first two films''.
* FunnyCharacterBoringActor: Fluffy the Hamster is so dull and pessimistic that he's hilarious.
* IronyAsSheIsCast: Pickles the guide dog is voiced by a visually impaired woman.
* ReferencedBy:
** ''Westernanimation/FlushedAway'': A Captain Cuddlepuss toy is shown close to Roddy's cage.
** ''Westernanimation/WallaceAndGromit'':
*** The puma is shown stuffed in ''Westernanimation/TheWrongTrousers''
*** Photos of the characters can be found in ''Videogame/WallaceAndGromitInProjectZoo''.
* ThrowItIn: The entire point of the films. Nothing is scripted, all of the interviews are 100% authentic and all of the art and animation are done long after they've been edited down to a reasonable running time.
