This title in the Think About... series shows that while every animal needs things to protect it from the elements, only people can produce and choose to wear different kinds of clothing. A funny, kid-like question ("Does an ox wear an overcoat?") shows the animal in a silly scenario (e.g., sporting a purple coat). A turn of the page reveals why animals don't need clothes via a few facts about each animal's physiology, habitat, and habits. The pattern follows for a chimp, donkey, bear, and duck. Next, the function and options in human clothing is presented. A final "Think About" spread presents kids, parents, and teachers with activities that relate to and extend each book's subject matter.
