"She and Her Cat" was the work that made Shinkai popular and it led him to work on the production company CoMix Wave Films, for which he produced his other films. At first he received "a very long e-mail" from the company in which there was a review telling why they appreciated the work and he was subsequently hired. The movie caught the attention of Mangazoo (who would become Comix Wave) and the company released the movie in a CD-ROM format. It contained its soundtrack and three different versions of the movie: the full five-minute version, a three-minute version, and a one-minute-and-half digest version. After it was out of print, it was also included in the DVD release of "Voices of a Distant Star" as an extra.
