This story is about a cat that is constantly on the lookout for his friend, Little Mouse. He begs him to come out every day, but the mouse refuses every time. The story incorporates the days of the week by having something different happen as each page is turned. It also uses patterns of repetition in the writing which can make it easier for kids to read and follow along. I would probably use this book with younger students, probably kindergarteners, as a read aloud to review days of the week and to encourage students' participation with the repeated phrases.
