In January 2004 Jeffery Masson began an experiment he'd been dreaming about for years: he rescued a puppy, a kitten, two chicks, two rat pups, and a rabbit, and decided to raise them all together in his home with his family, observing them for a year. This experiment led to friendship, tolerance, cooperation, and even love and compassion between the animals. Here is Masson returning to what he does best: exploring the emotional lives of animals. This book will appeal to anyone who has ever wondered what animals think and feel - and to anyone hoping for a more tolerant world.

Jeffrey Moussaieff Masson has written more than a dozen books, including the New York Times bestsellers Dogs Never Lie About Love and When Elephants Weep. A longtime resident of Berkeley, California, he now lives in New Zealand with his wife, two sons, six cats, and a menagerie of other animal companions.
