I really enjoyed this book! The stories were so full of details that I never finished reading a story with unanswered questions. The illustrations fit very well with the book. The explanations about the psychology behind why the animals did what they did were easily understood. The set up made it easy to find each of the stories and look up the references. All in all, the author did a terrific job! I recommend this book for all animal lovers and non-animal lovers 12 and up!
