After the tragic loss of her beloved cat Suu, manga artist Chie Shinkyuu decides to adopt a new feline companion. Following a tip from her brother-in-law, she picks up a stray named Sen—a rambunctious, food-obsessed cat who quickly becomes both a source of chaos and immense joy. Later, a second cat, Tsubu, joins the household: a small but imperious feline who rules the roost like a queen. The story follows Chie’s daily life as she juggles her demanding career with the antics of her two cats. Sen’s insatiable appetite and tendency to cause destruction are matched only by his affectionate nature, while Tsubu’s aloof demeanor hides a deep bond with her owner. Over the course of five volumes, readers witness the cats grow from mischievous kittens to lovable older animals, experiencing everything from chaotic vet visits, intense naps, territorial squabbles, and moments of quiet comfort. The narrative highlights the pure, unfiltered joy of living with cats—the scratches, the interruptions, and the unconditional love, capturing the essence of cat ownership with humor and warmth.
