Barron's ``Pet Handbooks`` are written, designed, and illustrated in much the same attractive style as Barron's best-selling ``Complete Pet Owner's Manuals.`` However, ``Handbooks`` have a larger page count and with it, more extensive and detailed coverage of each title's subject pet. This updated edition for guinea pig owners provides a wealth of information on the animal's anatomy and life cycle, plus advice on caging, feeding, and health care.
