When Cat loses a tooth, the Tooth Fairy delivers a wholly unwanted sidekick: a mouse. Together, Cat and Mouse are tasked with running a few Tooth Fairy-related errands—a challenge, since Mouse is just as competitive and mischievous and hilariously self-involved as Cat. The stakes rise and so does the deadpan humor, culminating in a satisfying surprise that will leave readers eager for yet another delightfully devious Cat adventure.
