George Herriman's Krazy Kat returned to animated form in 1963 as part of King Features Syndicate's syndicated anthology package that also included Beetle Bailey & Snuffy Smith. Unlike those other strips, Krazy and Ignatz Mouse had some previous experience, appearing in a series of theatrical shorts for Columbia in the early 30's.
The biggest dispute over Krazy has to do with gender. Herriman intentionally made Krazy gender-neutral, but in the KFS shorts, produced by William Snyder & Gene Deitch, Krazy is clearly female, swooning over Ignatz despite his hatred of her. Otherwise, the androgynous status of Krazy remained intact in the comics and likely also in those Golden Age shorts. Snyder & Deitch didn't exactly endear themselves to fans of Tom & Jerry or even KFS stablemate Popeye, so ya wonder what was it that got them the contract to handle Krazy & Ignatz's misadventures.....!
