a natural birth of a sphynx cat happened on a minnesota farm. the owners found hairless kittens in several litters of their domestic shorthair barn cats in the mid-1970s. two hairless female kittens born in 1975 and 1976, named epidermis and dermis, were also an important part of developing the breed. more hairless cats were found in texas, arkansas, and minnesota. so, the modern sphynx breed began with the canadian cats and the minnesota cats.
