The Masterful Cat Is Depressed Again Today Vol. 1 (manga)

A sweetly comedic manga about a cat who cooks, cleans, and succeeds at adulting more than the woman who expected him to be a pet!Saku is an ordinary young woman who works long hours and lives alone with her cat, Yukichi. Yukichi, however, is not an ordinary house cat. For one, the temperamental feline towers over Saku and walks around on two legs.

Instead of playing with toy mice, he scours supermarket flyers for good deals and keeps the house spotless. With a pet like that, it's hard to tell who's taking care of who!
