Herman and Katnip are a duo of cartoon characters (Herman the mouse and Katnip the cat), who have appeared both separately and together in Famous Studios cartoons from 1944 to 1960. 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. Despite this, Katnip rarely had trouble forcing Herman to pay in some manner for his victories. Arnold Stang voiced Herman while Sid Raymond voiced Katnip.
Leonard Maltin's published history of Hollywood cartoons Of Mice and Magic described the Herman and Katnip series as a prime stereotype of the "violent cat versus mouse" battles that were commonplace among Hollywood cartoons of the 1920s through the 1960s. The violence in this series, while intended for comedic effect, often reached a level of brutality that surpassed both Tom and Jerry, Mighty Mouse, and Warner Bros.' Sylvester the Cat. Herman's battles with Katnip always ended with Herman victorious over Katnip, and frequently Herman and his mouse companions would sing a victory song as they observed Katnip being brutally punished or even tortured (e.g. being eaten by sharks, killed in a rockslide while mountain climbing, strung up with Christmas lights and plugged into an electric socket, or even dying and his ghost being sent to "the fiery furnace".)
Katnip also had his share of running battles with Buzzy, a singing black crow in a flat straw hat. This was usually based on Katnip trying to kick an ailment. He would read a rhyming verse that suggested crow meat as the sure cure. Once confronted by Katnip, however, Buzzy would propose another solution, to which the cat usually replied, "Hmmmm, that sounds logical."
Herman and Katnip and the other original Famous characters were purchased by Harvey Comics in 1958, who continued to promote the characters under the name Harveytoons. The early Herman and Katnip cartoons were sold by Paramount in 1955 to U.M.&M. T.V. Corp. for television distribution.
