"In The Emotional Lives of Animals, Marc Bekoff has pulled together the growing body of scientific evidence that supports the existence of a variety of emotions in other animals, richly illustrated by his own careful observations ... Combining careful scientific methodology with intuition and common sense, this book will be a great tool for those who are struggling to improve the lives of animals in environments where, so often, there is an almost total lack of understanding. I only hope it will persuade many people to reconsider the way they treat animals in the future."--Jane Goodall, from the foreword.
