In three short chapters of just a few words each, Lobel demonstrates her artistry for choosing the right ingredients to create a perfect concept book around the life of a small gray-striped cat. “All Week Long,” the first story or chapter, presents not only the days of the week, but also colors, and in the process, accomplishes a fine assessment of one little girl's activities by focusing, cat’s-eye view, on her footwear. Tuesday's flashy red cowboy boots take her bike-riding, and Saturday’s demure pink toe shoes inspire Nini, the cat, to lift an elegant paw and so on. The second segment, “Nini's Year,” evokes much more about months than simply their names, even during March, when the howling winds Nini listens to wouldn't seem to give an ordinary artist much to go on visually. The surprise here is the Nini of December, who “waited for good things,” and proudly accepts her holiday gifts—three gray-striped kittens. The titular third story may seem a book-bulking appendage or a pretext for including number concepts, but it is also the necessary expansion of Nini's world, for she is a cat of the outdoors. Here her presence is diminished so that sometimes only a head peeps from the edges of white-framed illustrations depicting life around her home near a lighthouse. The book's culminating spread shows one moon smiling at a 100-starred cat constellation above a very tiny cat. There's neither a missing elementary concept nor a jarring fly in the ointment of this bewitching cat's charmed life. (Picture book. 4-6)
