This clip is best known online as a reaction sound rather than as a formally credited audio source. It circulates in meme edits, reposted pet videos, and short-form reaction compilations where creators use it as a comic stand-in for disappointment. The appeal is simple: a real cat noise mimics the rhythm people associate with a sad trombone, so the joke reads fast even with no context. That mix of animal audio and familiar meme timing has kept it useful in viral edits across different platforms.
