Dekiru Neko wa Kyou mo Yuuutsu

Saku Fukuzawa lives alone and works long hours, while her home life is chaotic enough that it would probably collapse without her black cat Yukichi. The problem is that Yukichi is no ordinary pet anymore: he has grown nearly as tall as a person and cooks, cleans, shops, and packs Saku's lunches far better than she ever could.

Outside the apartment, Saku tries to hide the fact that a giant cat effectively runs her household. Inside, Yukichi behaves like a strict homemaker, scolding her when she neglects herself or comes home too late. Their roles are completely reversed, but beneath the comedy is a genuine dependence: Saku rescued Yukichi when he was small, and he now repays that kindness every day in his own way.
