Automatic litter boxes became a familiar sight in pet owner videos and gadget reviews as self-cleaning models grew more common in homes, and their distinctive motor sound quickly became shorthand for futuristic pet care. Creators reuse this short clip to signal that a machine, not a person, is handling an unpleasant chore, often for comic effect. Because it lasts under two seconds, it fits easily into short-form edits, reaction videos and memes about cats, laziness and smart home gadgets, where a single recognisable mechanical noise can set up a joke instantly.
