Herman and Katnip are a duo of cartoon characters (Herman the mouse and Katnip the cat). From 1944 to September 1950, Herman appeared without Katnip, who made his first appearance in November 1949 with Mice Meeting You. The two characters continued to star in animated cartoons by Famous Studios until 1959. Their cartoon series, which was distributed by Paramount Pictures, together is essentially a clone of MGM's Tom and Jerry. The key difference is that, regardless of who personified good or evil (with Katnip being the latter on almost all occasions), Herman always came out on top against Katnip, while Tom won his fair share of comic battles against Jerry.[citation needed] However, Katnip rarely had trouble forcing Herman to pay in some manner for his victories. Arnold Stang voiced Herman while Sid Raymond voiced Katnip.
