This suggests that Felix may have slowly evolved from these precursors, instead of first appearing in "Feline Follies". Animation historian Gerald Carr has attributed the lettering of "Feline Follies" to Pat Sullivan, based on similarities with Sullivan's known works. The line art and visual forms of the film were also found to be similar to Pat Sullivan's previous works on comic strips. The dialogue in "Feline Follies" appears in written form. A litter of kittens uses the term "Mum" for their mother, a spelling more common to Australian English and British English than American English. Messmer also had a background in comic strips, and he reportedly had a "quite proficient" drawing style, with "well-crafted line work and very convincing volumetric forms". Sullivan's drawing style appeared "rougher" and had a "more angular execution". A number of "incongruous" design features and contrasting design styles in "Feline Follies" and other early Felix short films may indicate that more than animator was involved in its production. The serenade scene of the film was recycling a serenade scene from "Charlie in the Farm". Tom's reaction to the prospect of becoming a stepfather was recycled from another scene of the same film. In "Charlie in the Farm", a male bird marries. Following the marriage, he discovers that his wife has chicks from a previous relationship. The male bird runs away from his new family. "Feline Follies" was released on November 9, 1919, as one of the films in the "Paramount Screen Magazine". The initial distributor was the company Famous Players-Lasky (later known as Paramount Pictures). The distribution of the "Felix" was subsequently handled by Margaret J. Winkler and by the company Educational Pictures.
