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.
