This under-two-second clip is a short spoken line from the Ren & Stimpy cartoon, with a character stating plainly that he is the cat. It lands as dry, absurd and a little smug, the kind of flat declaration that gets funnier when it answers a confused question or settles a silly argument about who is who.
