When Cat and Mouse stay out late to play, they have fun until it gets dark and they hear strange noises. But then they meet a new friend, Owl. "Don't be afraid," he tells them. "It's a beautiful night." Cat and Mouse don't understand. How can it be beautiful when it's so dark and scary? So Owl invites them to reconsider night, from a vantage point at the top of his tree.
In the third of his Cat and Mouse books, Tomek Bogacki -- whose fables for the very young have been likened to those of Leo Lionni -- confronts children's fear of the dark by showing them an alternative in his soothingly beautiful nighttime pictures.
So... I think this book is about trying new things and looking from a different perspective... but it also has predators playing with each other? Like the mice should be afraid of the cat AND the owl! But instead it hangs out with them like they aren't a threat to their very existence. Weird message.
