Since the first edition of Between Pets and People in 1983, the authors' then-startling contention that pets benefit our mental and physical health has found wide acceptance. Evidence in our daily lives - in television pet food ads, in doctor's offices outfitted with aquaria - attests to how widely the belief in pets' therapeutic influence is now held. This revised edition of Between Pets and People, with additional data and case studies and expanded references - including a listing of Internet resources - and a foreword by Elizabeth Marshall Thomas, analyzes the surprisingly complex relationships we have with our pets. This book contains an important lesson for everyone - to accept ourselves and others in the uncritical way that pets accept us, and come to terms with our own animal nature.
