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 brand new handbook for guinea pig owners provides a wealth of information on the animal's anatomy and life cycle, plus advice on caging, feeding, breeding, and health care.
