- Casting Gag: Catnip as Bill Cosby in "Sleeping Kitty", as Cree Summer was in A Different World (spinoff to the Cosby Show).
- International Coproduction: While sending off shows to be animated in Japan was extremely common in the 80's-90's, the show was partially produced in Japan to help promote Sanrio products overseas (again it was the 80's). It didn't really catch on, but Hello Kitty did reach international recognition years later.
- Keep Circulating the Tapes: While most of the episodes were released on DVD, the intro, ending credits, and the bumpers are missing because MGM decided to organize the shorts by theme. Most importantly, "How Scrinchenip Stole Christmas" is the only episode not in any of the DVDs. Luckily, Hulu and iTunes released the episode with everything intact.
- It was even briefly on Netflix Instant (way before it became huge too), but is no longer available as of now.
- It can currently be seen for free on VUDUnote .
- Marth Debuted in "Smash Bros.": Likely the intention of the inclusion of My Melody (and to a lesser extent Tuxedo Sam) it was the 80's after all. Considering how she was (and still is) extremely popular in Asia on par with Hello Kitty, but at the time the show came out was practically unheard off in the West. Unfortunately considering how the show only lasted one 13 episode season, it didn't really work out that way. However, My Melody does have a small cult following in the West today.
- Relationship Voice Actor: Bert, Schaeffer, and Bentley are Hello Kitty's father, grandfather, and seal friend, respectively.
- What Could Have Been:
- Originally the casting director wanted Tara Strong to voice My Melody and Mairon Bennett to voice Hello Kitty, but at the last minute, their roles were switched.
- A second season was planned but low ratings cancelled the show.
