Cat screams have been a staple of comedy sound design for decades, from classic cartoons to viral pet videos, because the sound is instantly recognisable and hard to ignore. Online, short clips of startled or angry cats spread through reaction videos, gaming streams and TikTok edits, where editors reuse the scream to exaggerate surprise or embarrassment. Its popularity endures because it works without context: even viewers who have never seen the original clip understand the panic, frustration or drama it is meant to signal.
