Two-year-old Leo is not your average house cat. One day he notices his young neighbor Tatsuru on his way to elementary school and he then decides to follow him and enroll himself! After finding his own backpack and school equipment, young Leo realizes that anything Tatsuru can do, he can do as well! And best of all, since he is a feline he can do it all with a style and flair all of his own. Leo can go to school! Leo can live on his own! Leo can find a part-time job or even be chef! Eventually Leo's life is full of wonderful memories, but it could have taken a very different turn if not for those who loved him.
