If imitation, as they say, is the sincerest form of flattery, then FamousStudios' '''''Herman and Katnip''''' certainly flattered Creator/{{MGM}}'s WesternAnimation/TomAndJerry. Given that any mouse and cat cartoon is going to have some similarities with any other cat and mouse cartoon, the resemblances of the characters is still quite striking.

Herman the mouse in particular bears a strong resemblance to Jerry the mouse. Katnip the cat did not look quite so much like Tom the cat, but you would be forgiven if you thought you knew where the inspiration for the cartoon character came from.

Herman and Katnip did diverge from Tom and Jerry in two respects. The characters spoke: Katnip in a dopey SimpletonVoice, Herman in a Brooklyn twang. The standard episode setup was different, too: Herman's cousins Reuben, Dubin, and Louie (and other, unnamed mice) would be having fun at some activity; Katnip would arrive to persecute them; then Herman would arrive (often coming "from the city") to defend them.

Herman was voiced by Arnold Stang, who later supplied the voice for TopCat. There is quite a similarity between the mouse's voice and that of Leo Gorcey of the Bowery Boys. Syd Raymond supplied the voice for Katnip. Raymond was also the voice of WesternAnimation/BabyHuey.

Herman and Katnip are not remembered like MGM's cat-and-mouse pair; not only, perhaps, because they appeared on cinema screens later than their more famous rivals, but also because the personalities of the pair were possibly not quite as engaging. Also, the Famous Studios' cat-and-mouse series did not receive as many later television airings as Tom and Jerry enjoyed.

If Herman and Katnip lacked anything in personality, they tried to make up for it with action. For "action" read blowing Katnip up; sending Katnip off a cliff; squashing Katnip with a 100-ton weight, and so on. With so much emphasis placed on violence—almost all of it delivered to the cat—it's no surprise that Mike Reiss, a writer on ''WesternAnimation/TheSimpsons'', [[WordOfGod confirmed]] that Herman and Katnip, not Tom and Jerry, were the real inspiration for [[WesternAnimation/TheItchyAndScratchyShow Itchy and Scratchy]].

When the series ended, it wasn't so much because the cartoons ran out of steam, as because the studio sold all its ongoing characters to Creator/HarveyComics, which had licensed them for several years. But Herman and Katnip didn't go on to very great success at Harvey. They appeared in the back pages of a lot of comics during the 1950s and early 1960s, and were featured in an occasional issue of ''Harvey Hits'' (a later Harvey title with rotating stars), but never had their own comic book. When other Harvey characters were re-adapted into animated form—even some who, like ComicBook/RichieRich and Wendy the Good Little Witch, had never been animated before—''Herman & Katnip'' weren't. [[note]] though their segment were added to the "Casper the friendly ghost" cartoon, along with segments with WesternAnimation/BabyHuey and WesternAnimation/LittleAudrey. [[/note]] Eventually, they faded from view, and are now scarcely remembered.

With that said, in October 2011, a complete DVD set of all their adventures was released.

* AmusingInjuries
* AnvilOnHead
* ArtEvolution: Katnip had a drastically different design in his early appearances before they settled on his dopier look and color scheme.

** Check out the [[http://www.youtube.com/watch?v=1uvp3xXbTrA&t=2m48s "wheel of knives"]] gag at about 2:48. Katnip throws knives at Herman, hitting a wheel instead. Herman hops on top of it and rolls it after Katnip, slicing off segments of his back until he falls flat. Ouch.
* FamilyUnfriendlyDeath: Several of the cartoons end with Katnip being killed, and the mice playing around with his dead body. (For example, using Katnip's body as a Christmas tree in ''[[http://www.youtube.com/watch?v=0CEJFLCSGH0&t=5m50s Mice Meeting You]]'').
