The Donskoy is known by several names that reflect its origins and characteristics. The official breed name "Donskoy" comes from the Don River region in Russia where the breed originated, specifically the city of Rostov-on-Don. This geographic naming convention honors the breed's Russian heritage. The name is pronounced "don-SKOY" and is used in most international cat registries that recognize the breed. In English-speaking countries, the breed is commonly called the "Don Sphynx," which emphasizes its hairless characteristic while distinguishing it from the better-known Canadian Sphynx.
The alternate name "Don Sphynx" or "Don Hairless" is frequently used, particularly outside Russia, to help people understand the breed's most obvious characteristic. However, it's important to note that the Donskoy is genetically distinct from the Canadian Sphynx despite both being hairless. The hairlessness in Donskoy cats is caused by a different dominant gene, while the Canadian Sphynx's hairlessness comes from a recessive gene. This genetic difference means the breeds cannot be used interchangeably in breeding programs, and they have distinct characteristics beyond just their lack of fur.
Other informal names occasionally used include "Russian Hairless" or simply "Don cat," though these are less common in official contexts. The World Cat Federation (WCF) recognizes the breed officially as "Donskoy," while The International Cat Association (TICA) also uses this name. Some Russian breeders and enthusiasts use the Russian name "ΠΠΎΠ½ΡΠΊΠΎΠΉ" (Donskoy) or "ΠΠΎΠ½ΡΠΊΠΎΠΉ ΡΡΠΈΠ½ΠΊΡ" (Donskoy Sphynx). Regardless of the name used, all refer to the same distinctive hairless breed from Russia with its unique dominant hairless gene and characteristic appearance that sets it apart from other hairless cat breeds.
