Alternate titles for this film were Man-Eating Tiger and Hold That Tiger. Rose Caylor and Ben Hecht were married. According to Daily Variety news items, Melville Brown joined Fox to direct the film, but he asked for his release during the first week of shooting because he was dissatisfied with the treatment of the story and believed that some of the principal roles were miscast. Clyde Bruckman was borrowed from Columbia to replace Brown. Also, according to Daily Variety, Harold Schuster, formerly an editor, got his first directing assignment on this film doing additional scenes. According to the final shooting script in the Twentieth Century-Fox Produced Scripts Collection at the UCLA Theater Arts Library, Theresa Maxwell Conover was scheduled to play the role of "Mrs. Ingals." Minnie, who played "Mina," the tiger, was borrowed from the Los Angeles Zoological Gardens, according to a Hollywood Reporter news item. According to information in the Twentieth Century-Fox Records of the Legal Department, also at UCLA, T. L. Sappington, who wrote a story also entitled "Spring Tonic," which was published in Everybody's Magazine (Jun 1923), granted the studio the right to use the title.
