The Goodbye Cat by Hiro Arikawa

Against changing seasons in Japan, seven cats weave their way through their owners’ lives. We meet Spin, a kitten rescued from the recycling bin, whose simple needs teach an anxious father how to parent his own human baby; a colony of wild cats on a holiday island shows a young boy not to stand in nature’s way; a family is perplexed by their cat’s devotion to their charismatic but uncaring father; a woman curses how her cat constantly visits her at night; and an elderly cat, Kota, hatches a plan to pass into the next world as a spirit so that he and his owner may be together for ever.
