New Cat loves everything about living in Mr. Kim's tofu factory, except for one thing: she has seen a mouse in the production room, where Mr. Kim doesn't allow her to go. She knows that one of her jobs is to chase mice, but how can she do this if she can't go where they are? In this charming picture book, Yangsook Choi tells the story of the night that New Cat follows her instincts rather than Mr. Kim's wishes and gets more than she bargained for.
