A Man and His Cat, Volume 1: 09/10/20
A Man and His Cat, Volume 1 (おじさまと猫 1) by Umi Sakurai was voted the best manga by booksellers in Japan in 2018. It's now being released in English. The cat is a funny looking Scottish fold who has been overlooked by everyone in the pet shop. He's now a year old and figures he's un-adoptable. When he has given up hope, a man comes and adopts him.
Through brief flashbacks we learn that the man and his wife had wanted to get a cat but never did. He's clearly a widower now and to honor his wife's memory, has decided to adopt the cat.
The first volume is primarily the two getting to know each other and settling on new routines. I'm reminded of My Roommate is a Cat (同居人はひざ、時々、頭のうえ). Except here, the man has done his homework and truly wants a cat in ways that Subaru hasn't.
The second volume in translation was released in July 2020.
