The origin of this clip is not documented, and no specific video, show, or uploader is attached to it with confidence. It circulates as a short user-uploaded soundboard clip built around the novelty of a cat making a bark-like "inhau" sound, the Portuguese onomatopoeia for a dog's bark. Because the joke is entirely about mistaken identity between two animals, it keeps being reused in pet meme edits and comedy compilations, where the absurdity of a barking cat needs no backstory to land.
