Julius the Cat is a fictional anthropomorphic cat created in 1922 by Walt Disney and Ub Iwerks. He first appeared in the very first animated series created by Disney, the Alice Comedies, making him the predecessor of Oswald the Lucky Rabbit and Mickey Mouse. Julius is an anthropomorphic cat, appearing intentionally similar to Felix the Cat. A bold and inventive hero, he gradually became the primary focus of the Alice Comedies, to the point Disney abandoned live action for pure animation on subsequent projects.

The Alice Comedies are a series of animated/live-action shorts created by Walt Disney in the 1920s, in which a live action little girl named Alice and an animated cat named Julius have adventures in an animated landscape. The shorts were the first work by what ultimately became The Walt Disney Company.
