Sphynx

🌍 Overview

The Sphynx traces to a spontaneous mutation in 1966, when a domestic cat in Toronto gave birth to a hairless kitten. Breeders identified the trait as recessive and spent more than 30 years developing the breed by outcrossing to normal-coated cats, including Devon Rex and American Shorthair lines, and most modern Sphynx descend from two kittens found in Minnesota in 1975 and three found in Toronto in 1978. That repeated outcrossing left the breed genetically healthier than its rarity suggests, with observed heterozygosity of 0.58 against a purebred average of 0.51. The consequences of hairlessness are real and permanent: the oil glands work normally but there is no coat to absorb the secretions, so the skin stays greasy and needs routine bathing, and the cats sunburn easily, carry high rates of Malassezia yeast, and regulate body temperature poorly. The breed also carries a striking burden of hypertrophic cardiomyopathy, and in UK primary-care life tables the Sphynx had the shortest life expectancy of any breed reported, 6.8 years from birth against 11.7 years for cats overall. Since 1 January 2026 it has been prohibited to keep a hairless cat in the Netherlands, which in practice ends acquisition too, though trade and import were considered and deliberately left out of the decree as redundant. Breeding them had already been unlawful there since 2014. A cat that was already being kept before that date may be kept for the rest of its life, and may still change hands, provided the keeper can produce written proof of the date its microchip was placed or registered.

📜 History

Hairless cats had appeared and vanished before. E. J. Shinick of Albuquerque acquired a hairless brother and sister, Dick and Nellie, from Pueblo neighbors around 1894 and described them in a letter printed in Frances Simpson's The Book of the Cat in 1903, where they were advertised as the last of an Aztec breed. Dick was killed by dogs within a year or two, Nellie was sent east and died soon after reaching the Smithsonian Institution, where she was mounted as a specimen, and the line ended with her. Nothing was salvaged from that mutation, so the modern breed rests entirely on the Canadian line. The CFA accepted the Sphynx for registration in 1998 and granted championship status in 2002.
