More than the story of how people and rats live together, this book takes a serious and intriguing look at science and scientists, the problems they solve and fail to solve, and the scope and imperfections of our scientific knowledge of the world. It answers questions such as: Are rats still a threat to human health? Do rats think? Is it true that wild rats sometimes die, unwounded, from social stress? Can studies of rat societies tell us anything useful about our own social lives?
