Book excerpt: Does living with a pet really make people happier and healthier? What can we learn from biomedical research with mice? Who enjoys a better quality of life—–the chicken destined for your dinner plate or the rooster in a Saturday night cockfight? Why is it wrong to eat the family dog? Drawing on more than two decades of research into the emerging field of anthrozoology, the science of human–animal relations, Hal Herzog offers an illuminating exploration of the fierce moral conundrums we face every day regarding the creatures with whom we share our world. Alternately poignant, challenging, and laugh-out-loud funny—blending anthropology, behavioral economics, evolutionary psychology, and philosophy—this enlightening and provocative book will forever change the way we look at our relationships with other creatures and, ultimately, how we see ourselves.
