Guinea pigs are a popular pet, 'cute but dim' friends for those looking for an alternative to dogs and cats. They are increasingly bred for looks, shaped by humans in search of an ideal appearance. But it was guinea pigs that influenced humans from as early as 5000 bc, when their domestication began a long and fruitful relationship, influencing scientists such as William Harvey, and painters from Jan Brueghel to Beatrix Potter. Guinea pigs are more than simply pets: they have been at the centre of countless works of art and literature, inspiring children and adults alike. Guinea Pig is the first book of its kind to take an in-depth look at the fascinating history of guinea pig and human interaction. It examines guinea pigs' roles as pets alongside their roles as sacrificial offerings to Inca gods, a dish at the Last Supper, and the mascot of the airmen's Guinea Pig Club.
