Little Cat goes to school on the big red bus with her big sister. But one day, Little Cat’s big sister is sick and Little Cat must go to school on her own. Unfortunately, on the way back home, Little Cat falls asleep on the bus and no one notices. When she wakes up the bus is empty and it’s dark outside. As soon as the bus driver realises what has happened, he sits her in the very special spot up the front of the bus and takes Little Cat home.
