Where did the Colorpoint Shorthair cat originate?
The Colorpoint Shorthair cat originated in the 1940s in the U.S. when breeders attempted to introduce red point and cream point into the Siamese stock — previously forbidden colors by the Cat Fanciers’ Association (CFA). The CFA only permits four colors in the Siamese: lilac, chocolate, blue, and seal points. To achieve the new desired red pointed color scape, they were crossed with Abyssinians and American Shorthairs, though the breed is mainly Siamese today. Some associations consider the Colorpoint Shorthair a variety of Siamese.
