One day, in  Sakura town, the slightly tipsy  Satou Moe stumbles into a  round cushion-shaped thing that turns out to be the cat  Poyo. It was a fated encounter, so Moe adopts the stray. Many small daily-life adventures await the Satou family: Moe, her brother  Hide (a high school student), father  Shigeru (a farmer) and the mysterious, at times fast, high-jumping, gentle and very cute Poyo, who even likes to take baths.
