American crested guinea pig is a single color with a plain white crest. Also known as the American Crested, the White Crested Guinea Pig is a somewhat rare and very unique-looking breed. These little princes and princesses have what looks like a white crown on their heads. They also have the same sparkling personalities as other breeds of guinea pigs, even though some say their crest makes them look like they are perpetually angry.
White Crested Guinea Pigs present quite a challenge to breeders, because as few as one in fifty of them conform to the breed standard. Although a showable White Crested is hard to find, those that have the correct markings often do well at shows.
