As cats are known to be difficult to train unlike dogs, it has been said that the novel could never be made into a movie. In order to overcome this issue, cat trainer Kitamura Mayumi from major animal actors production house ZOO Doubutsu Pro was engaged to train the cats appearing in the movie. Even so, Arikawa who also takes on the role of scriptwriter for the movie was prepared to rewrite her script for the sake of the cats.
In order to get close to the male cat which will play Nana, Fukushi who is acting with animals for the first time, had to start interacting with the cat three weeks before the filming started and underwent lectures from Kitamura. Fukushi commented that he was a bit excited and worried about the distance between him and the cat but things got better by the time the filming began.
