Pete the cat loves his white shoes. He loves them so very much that he sings about them. One day while he is walking and singing he steps in some strawberries and his shoes turn red. But instead of becoming angry, he sings about how much he loves his red shoes. When he steps in mud and his shoes turn brown, instead of becoming angry, he sings about how much he loves his brown shoes. The book Pete the Cat: I Love My White Shoes by Eric Litwin and illustrated by James Dean is a great picture book about a cat that "goes with the flow."
Pete's philosophy is summed up at the end by his statement that "no matter what you step in just keep walking along and singing your song."
