Poyopoyo Kansatsu Nikki

Poyopoyo Kansatsu Nikki (ポヨポヨ観察日記) is a Japanese manga series created by Rū Tatsuki about a spherical cat named Poyo and the family that adopts him. It was adapted into an anime television series in January 2012. The anime is available subtitled in English on Crunchyroll. A video game based on the series in which players raise Poyo was released in April 2012 for the Nintendo 3DS.

Plot
Poyopoyo revolves around a spherical orange cat named Poyo, and the family that adopts him. The slice of life stories only have very mild continuity between them, and can be taken as stand-alone episodes. Episodes often deal with regular day-to-day interactions between family members, occasionally showing how family members celebrate holidays or deal with everyday inconveniences like rainstorms. At first, younger brother Hide dislikes Poyo, but as the stories continue, we see that Hide has grown somewhat attached to the family pet.
