C4 and P4 are two typical cats, who sleep all day and are awake at night. But what most people DON'T KNOW is what cats DO at night. Summer and Stacey, who belong to C4 and P4, are having trouble falling asleep. In their sleepy-time talk, the girls wonder what C4 and P4 would do if they could get out and about at night. And so the story goes . . . jumping on fences and riding in trucks, meeting with writers and artists, riding bikes with musicians and visiting the parks. Oh, the adventures these two cheeky cats have on their night journeys! And in the shadows, the mice watch carefully, awaiting their time for play . . . What do YOUR cats do at night?
