"Those CATegorical felines are back. This time they turn their attention to the characteristics of mammals, reptiles, amphibians, birds, insects, and fish. The energetic rhyming text and zany cartoon illustrations will captivate students and make it fun to learn about what makes each group distinctive. Goneau's cartoon creatures nicely complement the facts that Cleary imparts in his rhythmic narrative, and in several cases, labels are included in the illustrations to reinforce a point. Each volume concludes with two pages summarizing the key characteristics of the animal class under discussion. Solid additions to the series." --School Library Journal, Series Made Simple
