Cats Matilda and Hans seem to be opposites in every way. Matilda is quiet. Hans is loud. Matilda is well-behaved. Hans always misbehaves. One night Hans lets all the animals out of their cages at the zoo. The next day Matilda tells the police where to find Hans. Author/illustrator Yokococo's story may elicit genuine unease at this point among listeners and readers. Is this tattling? What about gender stereotypes? Not to worry. In a picture book that is far more sophisticated than it first appears, the capture of Hans delivers a delightful surprise that acknowledges a truth that even very young children will recognize: We all sometimes behave in ways both good and bad. Careful observers of the marvelous, stylized illustrations in this whimsical, seemingly simple story may enjoy going back and discovering the visual clues that are there all along. For example, Matilda is only shown by the bright light of day, while Hans is always pictured at night in this clever, artful offering. (Ages 3-7)
