The black and white tuxedo cat frequently drawn by Matataku. It's actually the artist's real cat (named after the moni-moni sound effect for cats kneading), which his wife found as a stray kitten (more on that in the commentary for post #1340999). Easily recognized by the black stripe directly above his nose and the black spot below his nose on his right.
Also it is the best cat ever.
