The phrase comes from a Russian pet anecdote about a dog that kept eating from the cat litter tray, prompting its owner to fit small doors to block access. The audio itself is a processed voice recording, credited in its file tags to an online voice changer, rather than a film or show clip. Short Russian meme sounds like this circulate on soundboards because the insult is instantly understandable to Russian speakers and funny even without context, so editors reuse it as a label for badly behaved dogs.
