* CreativeDifferences: Why a second season shall never be made (at least, not by Studio Deen). Due to a hand injury, creator Creator/NatsukiTakaya was able to have direct involvement with the anime adaptation... but she and director Akitaroh Daichi did not get along, and Takaya got a reputation for being a ControlFreak – for example, she demanded [[AllStarCast big-name seiyuu]] be cast, something Daichi normally avoids. Takaya also had issues with Daichi's work as well as the character designs. Unfortunately, Deen refused to let anyone other than Daichi handle the series, and Daichi has pretty much confirmed that he ''won't'' work with Takaya again.
* CreatorBacklash: A minor example. The "Collectors' Edition" triple-sized collections released in the late 2010s remove Takaya's popular margin comments, according to her because she'd changed as a person so much as to find them embarrassing and didn't want to write a whole new commentary for the manga.
** Takaya was never a fan of the anime (as noted above). The only reference she makes to it in her margin notes is to comment on the untimely death of Ritsuko Okazaki, who sang most of the songs, saying she liked "For Fruits Basket".
* CrossdressingVoices: Yuki, Ritsu, and Hiro in Japanese (but not English). and Momiji in both English and Japanese. Technically, [[spoiler:Akito]] counts too, in both English and Japanese… but this could not even be anticipated, as the anime was made years before the revelation that he is a she.
* OvertookTheManga: Barely averted. Due to Natsuki Takaya's hand injury necessitating a leave of absence from the series, the anime would have done this had it continued any longer than it did.
* ScheduleSlip: The artist, Natsuki Takaya, broke her left hand - her ''drawing'' hand - while working on the 8th book, forcing her to take an extended break from the series. This is one of the reasons that the anime ended the way it did; the other reason was the CreativeDifferences between her and anime director Akitaroh Daichi.
* StarMakingRole: The role of Tohru was this for Creator/LauraBailey.
** The English dub in general got many anime fans to start taking Creator/{{Funimation}} seriously as a studio (nearly every show they had dubbed up to that point was a [[Manga/DragonBall Shonen]] [[Manga/YuYuHakusho action]] [[Anime/DragonBallGT series]]).
* WhatCouldHaveBeen: [[WordOfGod Natsuki Takaya]] said she planned to have Ritsu and Mitsuru develop a relationship but she couldn't find a spot to fit it into the story. By the time she realized the story was still sitting there (and Ritsu hadn't made an appearance since his introduction) the manga was ending. Though a small mention at the finale gives the impression that it happened off-screen.
