The differences between the Donskoy and the Sphynx are a few. For starters, the Donskoy cat is from Russia, while the Sphynx comes from Canada. In addition, while they both have a gene responsible for their lack of fur, in the Sphynx, this gene is recessive ( meaning that it is not constantly modifying the genetics and that some cats might be born with the fur), in the Donskoy the gene is dominant (constantly influencing the newly born kittens). Both cats are affectionate and loving.
