Once Walt Disney received the notice on October 15, he convinced Roy to leave the hospital and help him set up his business. The next day, on October 16, 1923, Disney Bros. Cartoon Studio opened its doors at a small rented office two blocks away from his uncle's house with Roy managing business and Walt handling creative affairs. He convinced Virginia Davis's parents which caused the first official "Alice" short, "Alice's Day at Sea", to be released on January 1, 1924; delayed by eleven days. Ub Iwerks was re-hired in February 1925 and the quality of animation on the "Alice" series improved; this prompted Hugh Harman, Rudolf Ising and Carman Maxwell to follow Disney west in June 1925. Around that time, Davis was replaced with Maggie Gay and the cartoons started to focus less on the live-action scenes and more the fully animated scenes, particularly those featuring Alice's pet sidekick Julius, who bore an uncanny resemblance to Felix the Cat. In February 1926, Disney built a larger studio at 2719 Hyperion Avenue and changed the name of the company to Walt Disney Cartoons.
