This clip is a real recording of Floki, the cat belonging to Jakub and Aneta, presented as the short first meow in its set, rather than a clip taken from a film, show or game. Short pet sounds like this travel easily online because they are instantly recognisable, easy to drop into edits and need no context to understand. Creators use Floki's meow as a quick, affectionate reaction, and its brevity keeps it useful for videos, memes and messages where a longer animal sound would feel out of place.
