Inside the Viral 'Chicken Tender' Trend: How Sphynx Kittens Win over Skeptics
By Alexander Ross
Despite their ancient Egyptian namesake, the modern hairless cat does not hail from the Nile. The Canadian Sphynx lineage originated in 1966 in Toronto, Ontario, when a black-and-white domestic shorthair named Elizabeth gave birth to a hairless male kitten named Prune. While spontaneous hairlessness has cropped up throughout history, Prune's arrival spurred intentional breeding programs that isolated the specific genetic mechanism responsible for the look.
Wrinkled cat genetics depend on an autosomal recessive mutation in the KRT71 (keratin 71) gene. This gene directs the structural keratinization of the hair follicle. Because the mutation is recessive, both parents must carry the allele for offspring to emerge bald. When the follicle fails to produce a normal, stiff hair shaft, the hair either never erupts or breaks off at the skin level, leaving the surface entirely exposed.
The famous wrinkles are not actually unique to hairless cats; standard coated cats possess nearly identical folds across their faces, necks, and shoulders, but thick fur hides them from view. Without an insulating coat, the skin bunches up dramatically over muscle groups. Furthermore, the absence of fur creates a significant biological challenge: rapid heat dissipation. A Sphynx maintains an internal core temperature between 100.5°F and 102.5°F, but loses heat rapidly to the ambient air. To compensate, their basal metabolic rate operates roughly 20% to 25% higher than that of normal domestic cats, requiring calorie-dense diets just to stay warm.
