When Elephants Weep 
The Emotional Lives of Animals

For more than 100 years, scientists have denied that animals experience emotions, yet this remarkable and groundbreaking book proves what animal-lovers have known to be true: wolves, tigers, giraffes, elephants and many other creatures exhibit all kinds of feelings – hope, fear, shame, love, compassion. From Ola, the irritable whale, to Toto, the chimpanzee who nursed his owner back to health, this book collects together for the first time a vast range of case histories which show the extraordinary complexity of the animal world, and the tumult of emotions that govern it.
