Neko Atsume became the phone casual gaming flavor of the month in Japan in 2014. A year later, Neko Atsume was localized for English-language audiences, and the obsession spread globally. The beauty of the game is that it doesn't require a great deal of attention. Unlike similar but more demanding games from another time like Tamagotchi and Digimon, you don't have to press buttons to keep the cats alive. You don't even need to clean their kitty litter boxes, or groom them, or play with them. You just leave food and toys for them and check the yard for who shows up. You would hardly think that a game like that would lend itself to a cinematic treatment, but  AMG Entertainment has announced that a Neko Atsume movie is now in production, for release in 2017.
