Pupu is a plump, round calico cat who lives a contented but somewhat lazy life in a quiet Japanese neighborhood. Her days are filled with napping in sunbeams, begging for treats from her owner, and observing the comings and goings of the local human and animal residents. The story follows Pupu’s small daily adventures and misadventures, which often stem from her insatiable curiosity and her stubborn, opinionated personality. She is frequently joined by her feline friends, including a scrappy tomcat who taunts her and a shy, timid kitten she takes under her wing. The setting is an ordinary residential area, with the narrative focusing on the gentle humor found in a cat’s perspective on mundane human routines. Notable arcs involve Pupu’s encounters with seasonal changes, such as summer festivals that intrigue her and winter cold that tests her resolve to stay outdoors. Another recurring theme is her relationship with a neighborhood dog, leading to a series of standoffs and unexpected moments of mutual tolerance. The manga is episodic in nature, with each chapter presenting a self-contained slice of life, yet a subtle thread runs through the stories as Pupu gradually forms a deeper bond with her human family, learning to trust them even when they disrupt her napping schedule with baths or vet visits. The narrative tone remains light and warm, celebrating the simple pleasures and minor dramas of a house cat’s existence.
