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--anime announced! 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!

SUPER CAT TO THE RESCUE! Nishina is a part-timer at the supermarket near Saku and Yukichi and has run into them a few times. One day, she faints from overwork and lack of sleep. When Saku takes her to home to rest, it turns out that Nishina’s home is a total mess–almost as bad as Saku’s place before she took in Yukichi! Saku can’t bear to leave Nishina in these conditions, which means it’s time to call in the one and only masterful cat, Yukichi!!

THE PURR-FECT GIFT! To everyone in her office, Saku looks like she's got a perfect handle on things. What they don't know is that she's actually a disorganized slob, and only looks put together thanks to her masterful cat, Yukichi! With Christmas coming up, Saku wants to get Yukichi something special to thank him for all he does for her. Will she be able to find a present that's as unique as he is?!

SEPARATION ANXIETY Saku's been able to skip the biennial company retreat every time so far, but not this year! While she's out, her cat Yukichi will be watching the house, of course, but how long can Saku go without Yukichi's meals and warmth? And while Yukichi appears nonchalant about sending Saku off, how does he actually feel? The messy office worker and skillful cat are spending their first night apart, and boy, are they in for a long one!

BIRTHDAY SURPRISE! Saku's boss's niece, Yume-chan, is having a birthday bash and Saku and Yukichi are invited! They can't exactly parade a giant, bipedal cat out in public, but they also don't want to disappoint Yume-chan. How will they get themselves out of this pickle?! There's never a shortage of chaos and confusion in the Fukuzawa household, but at the end of the day, this messy office worker and skillful cat make it work!
