I got this book 2 years ago. Since then I have found myself referring back to it time and time again. It contains very detailed, but straighforward help on choosing a guinea pig, and caring for it, the anatomy of the guinea pig, A-Z of hamster diseases, breeding, and showing them. I have 17 years of guinea pig experience, and still found this book to contain things I didn't know about them. I would recommend this book to any guinea pig owner, no matter what experience you have. A truly brilliant book.
