The chant comes from a catchy Spanish-language children's song that found a second life online when TikTok users paired it with videos of cats dancing, bobbing and spinning to its rhythm. The simple, repetitive hook made it easy to reuse, remix and lip-sync, and the dancing-cat format quickly spread beyond TikTok to reels and shorts. It remains popular because the sound is instantly recognisable, cheerful and short enough to fit almost any lighthearted edit.
