Extremely disappointing. . Although claiming to be a study of human-animal relationships, this book offers an endless recital of man's inhumanity to man, to support the book's theme that man's history with animals has been even worse. Very poorly thought out and extremely long-winded, this book reads like an overblown Usenet message--"those other people are all so horrible, but we animal lovers are OK, aren't we?" Oddly, Serpell seems so rooted in the very "human supremacist" philosophy that he rails against, that he ends up reinforcing that very philosophy. Not enlightening at all; I feel like a pall has been cast over my relationships with both people and animals. You would learn far more by taking the money and time you might waste on this book, and spending them on your own dog or cat or whatever animal you please
