Other hairless breeds might have body shapes or temperaments that differ from those described above. There are, for example, new hairless breeds, including the Don Sphynx and the Peterbald from Russia, which arose from their own spontaneous mutations. The standard for the Sphynx differs between cat associations such as The International Cat Association (TICA), F\xe9d\xe9ration Internationale F\xe9line (FIFE) and Cat Fanciers' Association (CFA).

In 2010, DNA analysis confirmed that Sphynx hairlessness was produced by an allele of the same gene that produces the Devon Rex (re), with the Sphynx allele being incompletely dominant over the Devon allele and both recessive to the wild type. However a different genetic symbol (hr) is given to the Sphynx gene and it is more likely that these are different genes interacting with each other. The only allowable outcross breeds in the CFA are now the American Shorthair and Domestic Shorthair. Other associations may vary and the Russian Blue is a permitted outcross in the Governing Council of the Cat Fancy (GCCF). In Europe, mainly Devon Rex has been used for outcrosses.

In 1999 SGC Apophis Nordstrom of Classical Cats won the TICA International Alter of the Year. In 2006 SGC Classical Cats Valentino] won the TICA International Cat of the Year. In the CFA, GC, RW, NW Majikmoon Will Silver With Age was Cat of the Year for 2006. The following year, GC, RW, NW Enchantedlair NWA Cornflake Girl was Kitten of the Year. These awards are handed out for the highest scoring cats, across all breeds during the current show seasons. Regardless, Sphynx cat remain one of the rarest housecats.
