A cat entranced by a bird on the ledge outside its apartment slips through the open window, the departure unnoticed by the boy reading nearby. It’s the start of a city adventure for the intrepid feline, and an urgent quest for the boy once he discovers Spot (white cat with black spot) is missing. This intricate wordless story is rendered in detailed black pen-and-ink illustrations. Busy scenes of city life—buildings and bustling streets; an overhead view of kite flyers in a park; a parking lot farmer’s market; a cavernous, Grand Central-like station, and more—not only offer the chance to spot the wandering cat on almost every page (there are red herrings too), but to notice other whimsical elements. The boy’s journey is one of increasing worry, but sharp readers will note some near misses when he and Spot are close to each other. (The two pages when the boy looks most hopeless are notably Spot-less). It turns out Spot is perfectly capable of finding home again, and the reunion is sweet and satisfying. (Ages 4–7)
