Rat noises have long been used in film, theatre, and online video as a shortcut for dirt, decay, and neglect, because audiences instantly associate squeaking and scurrying with an unseen infestation. On soundboards and in editing libraries, short clips like this one are shared for creators who need a quick, recognisable animal effect without recording live rodents. It remains popular for Halloween content, horror parody, and comedy pranks, where a few seconds of squeaks can change the mood of a scene far more effectively than dialogue or music.
