This double feature adapts Sumino Eiko’s best‑selling children’s book. In “Chibi Neko Chobi,” the titular cat Chobi runs away from home after a scolding. The sequel, “Chibi Neko Kobi to Tomodachi,” follows adult Chobi, now a mother, who has given birth to a litter of four kittens. The youngest, a mischievous boy named Kobi, gets into trouble and ends up separated from his family.
