Charles Danten presents a disturbing vision of the role of animals in society. In Un veterinario encolerizado (to be published in English as Animal Secrets: The Shadow of the Human Saga), he urges us to think about our treatment of pets and laboratory animals. The author's controversial opinions will be of particular interest to professionals in veterinary science, ethics and species conservation, as well as the pet-owning public. The author believes that we have forgotten our humane values in society's treatment of pets. We should reflect consciously on the changes taking place on our planet and the role we assign to domesticated animals.
