To thrive, these friendly little animals require companionship with other gerbils, which means that owners should keep more than one. Gerbils also enjoy being gently held by their owners. Books in this series are written especially for inexperienced pet owners, for parents whose kids would like to have a pet, and for kids who simply want to learn more about animals that make good pets. Boys and girls are also introduced to the golden rules of pet care, and are advised on how to create affection and trust between themselves and their pets. Several gatefold pages in each book open wide to display attractive photo essays on animals and their care. Every book in this series contains approximately 80 full-color, high-quality photos, as well as instructive drawings.
