In this highly original and hugely enjoyable work, John Bradshaw examines modern humans’ often contradictory relationship with the animal world. Why, despite the apparent irrationality of keeping pets, do half of today’s American households, and almost that figure in the UK, have at least one pet (triple the rate of the 1970s)? Then again, why do we care for some animals in our homes, and designate others only as a source of food?
