The Cheshire Cat first appeared in Lewis Carroll's Alice's Adventures in Wonderland in 1865, famous for its broad grin and habit of vanishing while leaving its smile behind. The character became far more widely known through Disney's animated Alice in Wonderland in 1951, where its playful yet unsettling personality was brought to life on screen. Since then the cat's laugh has become shorthand for mischief and madness in popular culture, and short clips of it are now reused constantly in fan edits, reaction videos and memes.
