With no single famous source attached to this short clip, Pussycat has spread mainly as a handy, recognisable cat sound for online creators rather than as a quote from a show or film. It fits the same playful corner of meme culture as the cat laugh meme and the sad meow song, where a single feline noise can carry the whole joke. Creators keep returning to it because cats are instantly relatable online, and a brief meow needs no explanation, translation or setup to make a post feel funnier, softer or more surprising.
