Day and night, black and white—this playful tale of opposite personalities celebrates the adventure of sharing life's discoveries with a friend.Black Cat—black from the tips of his ears to the tip of his tail—only ever goes out in the day. But White Cat—white from her whiskers to her four furry paws—only ever goes out at night. He picks daisies, while she gazes at the stars. When they both feel the urge to explore a world beyond their own, Black Cat and White Cat go on a journey of discovery and meet for the very first time. Vividly illustrated with bold black-and-white art, each page paves the way toward a surprise (and surprisingly colorful) ending.
