Analysis of information sources in references of the Wikipedia article "Sphynx cat" in English language version.
In 1966 a domestic cat gave birth to a hairless kitten in Toronto Canada. It was discovered to be a natural genetic mutation and the Sphynx cat, as we know it today, came into existence.
But the modern-day Canadian Sphynx—the hairless breed we know in North America—has been defying expectations since the mid-1960s, when an Ontario cat gave birth to a hairless kitten, the result of a natural genetic mutation. Then, in the mid-1970s, two separate sets of hairless kittens were born to owners in Toronto and Minnesota. Thanks to various breeding efforts, their lineages resulted in the affectionate animal we love today.
