The Krazy Kat comics have been animated numerous times; starting in 1916. The first animated series contained the most relation to the actual strip, while later ones began to change certain aspects, including Krazy Kat's appearance- once resembling Mickey Mouse, another time Felix the Cat. Another appearance change was going to occur, by changing Ignatz from a white mouse to a black mouse. Krazy Kat's gender had been flipped around from time to time, since it is slightly a mistory. The series remakes had ended around 1964.
