Cats have been part of Minecraft since ocelots were added in 2012 and became separate mobs in the 2018 Village and Pillage update, with the hiss kept as their warning sound when threatened. Short clips of the effect spread through YouTube survival videos, TikTok edits and Discord soundboards because it is instantly recognisable even without gameplay on screen. Creators reuse it outside the game for real cats, annoyed characters and fake anger reactions, turning a tiny defensive noise into a universal shorthand for back off.
