Cat hisses are among the most recognisable animal sounds in online video, because almost everyone has heard a real cat use one as a warning. Softer versions like this one have become popular in short-form edits and soundboards, where creators want the attitude of a hiss without the harshness of a full confrontation. The short length makes it easy to drop into memes, reaction videos and pet compilations, and its lower intensity also suits jokes about mild annoyance, boundaries and grumpy pets. That versatility keeps it in regular use across social platforms.
