The little kids next door got confused about the names of the kitties. They combined Pepe + Macaroni and came up with Pepperoni. Given that both Pepe and Mac are B&W tuxedos, frequently hang out together, are the official household greeters, are always up to mischief, never get enough attention, and impose themselves on the other cats and the human at will, this name blending seems kind of appropriate.
