Julius Katz, better known as Julius the Cat, is an anthropomorphic cat.
Description
Julius was a feisty young fellow who struck a friendship with the human girl Alice. The two friends stuck together through hail and storm, Julius notably often protecting Alice from burly rogue Peg-Leg Pete. Later, with Alice's help, Julius married a cat girl (though that didn't stop him from being a bit of a lady's man still in later years). It appears that later on in life Julius settled down in a repair shop with the help of his sons.
Behind the scenes
Julius was created in 1922 and became the Walt Disney Company's first recurring cartoon star, appearing first as the only recurring character in the Laugh-o-Grams series, the prime supporting character in the Alice Comedies and briefly even a villain in the Oswald the Lucky Rabbit series.
At the request of producer Margaret Winkler, however, Julius was made very similar to rival cartoon star Felix the Cat, and so Disney moved on to a new character, Oswald Rabbit, as soon as possible.
Julius's last name, sons and final occupation were all created for the sake of a background tribute in Disney California Adventure. While Disney Parks infos are rarely considered canon, this comes to fill a void and is thus accepted as true.
