Monty Roberts has been studying horses for his entire life. His extraordinary ability to communicate with them has earned him the title "horse whisperer." He has written a new book about his life from studying wild mustangs in the Nevada desert to demonstrating his horse training methods to the Queen of England. The book is called "The Man Who Listens to Horses: The Story of a Real-Life Horse Whisperer" (Random House). Roberts was featured on "Dateline NBC."

Dr. Nicholas Dodman, a veterinary behaviorist, is the author of "The Dog Who Loved Too Much: Tales, Treatments, and the Psychology of Dogs" (Bantam) In the book, he describes his own methods for correcting dog behaviors, such as attacking the telephone when it rings or scaring company, and he includes many stories from his own practice.

Naturalist and biologist Roger Tabor has studied house cats for twenty years. He has prepared television series on felines for the BBC and has written several books on the subject. His latest book is called "Understanding Cats: Their History, Nature, and Behavior" (Reader's Digest).
