A mouse offers to demonstrate counting by using a calico cat that has "1 tail . . ". 2 big eyes . . . 3 black spots" --right up to "20 wet paw prints." This primary text appears in large type, and paragraphs of tiny type fill in details of cat anatomy, behavior, and lore. Illustrations in softly shaded colors--produced by many overlapping, fine crayon lines--depict the cat and her kittens washing their ears, playing in paper bags, watching birds from the window, and engaging in other characteristic activities, such as sleeping. The artwork's large scale makes the book a good choice for reading aloud to groups of young children, though in that setting, readers might want to skip the small print.
