Sylvester James Pussycat, Jr., often shortened to "Sylvester Junior" or simply "Junior," is an animated cartoon character. He is the son of Sylvester The Cat. Physically, Junior is basically a miniature version of his father, having a large head in proportion to a small body. Junior has been noted saying that he is 31/2 years old. He debuted in the cartoon Pop 'Im Pop!, directed by Robert McKimson. Joe Alaskey (after Mel Blanc's death) voiced both father and son. Junior possesses a degree of respect for his father, although often, when Sylvester does something embarrassing or humiliating, Junior often displays shamed and/or embarrassment of his father's behavior (sometimes donning a paper bag over his head). Often, Sylvester and Junior's shorts would feature Sylvester trying to capture Hippety Hopper, a baby kangaroo, to prove a point to his son. Each attempt at capture, of course, failed miserably, owing to Sylvester's invariably mistaking the kangaroo for a "giant mouse," and as such being taken completely by surprise by the kangaroo's athletic prowess, with Sylvester losing every fight, often in spectacularly humiliating fashion. Tweet Dreams was the so-far only pairing of Junior and Tweety in the Looney Tunes shorts, it was not a direct one; Junior basically served as a flashback image. After the original Looney Tunes shorts, Junior would show up sporadically in later years. In the 1990s animated series The Sylvester & Tweety Mysteries, Sylvester has a flashback to his childhood in the episode A Mynah Problem; in the flashback sequence, as with Tweet Dreams, Sylvester resembles his son physically.
