In each of these books by the author of Bodywatching an introductory essay is followed by a question-and-answer section (items one to four pages in length). The questions include ones about mating, hunting behavior, and physical characteristics. Morris writes very well, and his answers are often witty as well as informed. Nearly any reader would find these books interesting. Unfortunately, all of Morris's information is available from such other sources as encyclopedias and general dog and cat books, so a purchasing library is getting little new for its money. If your budget permits ``extra'' buying in the pet area, do acquire these books. Your readers will like them. But if the budget is tight, they are marginal purchases. Susan Matusak, Wilson Coll.
