Monsters, Inc. is Pixar's 2001 animated film about Sulley and Mike, where the human toddler Boo famously calls the big blue monster 'Kitty.' In the Latin American Spanish dub that nickname became 'Gatito,' and the line stuck with Spanish-speaking audiences who grew up with the film. Short clips of Boo's voice circulate on soundboards, TikTok and WhatsApp, usually shared as a cute reaction rather than a meme with a fixed joke. Its staying power comes from pure nostalgia: one word instantly recalls the film's warmest relationship.
