American Guinea Pig

American Crested (a.k.a. White Crested or simply Crested)
The American Crested, referred to simply as the Crested by ACBA and as the White Crested by ANCC, closely resembles the English Crested, in having a single rosette on the forehead. The breed standards and ideals are nearly identical, with the exception that an American Crested cavy's crest should be completely of a color different from the rest of the animal. Most usually the crest is white, as necessitated by the ACBA standard. No other white hair should be present in the animal. By this standard, American Cresteds are not bred in colourations that have white anywhere on the body, such as Dutch, roan, and Dalmatian.
