The huh cat became a staple reaction sound on TikTok, YouTube Shorts and Discord soundboards in the early 2020s as short form editing embraced pet reaction clips. The audio is usually paired with the image of the wide-eyed cat looking sideways, turning a simple meow into shorthand for confusion. Creators reuse it because it is short, recognizable even without video, and works across languages. It has since spread into meme compilations, live stream alerts and group chats wherever a baffled response is needed.
