Question: The Peterbald Russian cat breed resmebles the Oriental Shorthair which is closely related to which blue-eyed cat?
Context: Colorpoint Shorthairs are a variety of domestic cat.  Depending on the cat registry, they may be considered a separate breed of cat, or more often a variant of a pre-existing one, if accepted at all.  These cats are distinguished by their conformance to wide range of sixteen different point colors, beyond the four standard Siamese colors.  The variety was initially created by crossbreeding Siamese with the American Shorthair – the same mixture that created the Oriental Shorthair, but with different goals.  The Colorpoint Shorthair shares the point-coloration pattern with the Siamese, but in the nontraditional colors of red, cream, tortoiseshell, and lynx (tabby) points, and minor variations thereof.  In body style, head shape, and other features, it may be intermediate between the two foundation breeds, which show cats leaning toward Siamese traits.  Those who favour the Traditional Siamese look may also favour the more moderate-typed Colourpoint Shorthairs that take after their American Shorthair ancestors in shape. A domestic short-haired cat is a cat of mixed ancestry – thus not belonging to any particular recognized cat breed – possessing a coat of short fur.  In British English, they are often referred to as moggies.  Domestic short-haired cats should not be confused with the British Shorthair, American Shorthair or other standardized breeds with "Shorthair" names, which are breeds recognized by various registries.  Domestic short-haireds are the most common cat in the United States, accounting for around 90–95% of their number.  Other generic terms include house cat and alley cat (the latter may be used more specifically to refer to feral specimens).  The term tabby cat technically refers to a coat pattern, but is also often used as a general term for cats of this sort. The Peterbald is a cat breed of Russian origin.  It was created in St Petersburg in 1994 from an experimental breeding by Olga S. Mironova.  They resemble Oriental Shorthairs with a hair-losing gene.  The breed was accepted for Championship class competition in 2009. The Sokoke (or Sokoke Forest Cat in long form, and formerly the African Shorthair) is natural breed of domestic cat, developed and standardised, beginning in the late 1970s, from the feral khadzonzo landrace of eastern, coastal Kenya.  The Sokoke is recognized by four major cat pedigree registry organizations as a standardised cat breed.  It is named after the Arabuko Sokoke National Forest, the environment from which the foundation stock was obtained, for breed development primarily in Denmark and the United States.  The cat is long-legged, with short, coarse hair, and typically a tabby coat, though specific lineages have produced different appearances.  Although one rumored to be a domestic × wildcat hybrid, genetic study has not borne out this belief.  Another idea, that the variety is unusually ancient, remains unproven either way.  The native population is closely related to an island-dwelling group, the Lamu cat, further north. The American Ringtail Cat is a new experimental cat breed that started with a California cat named Solomon in 1998.  Owner Susan Manley started a breeding program to reproduce his unique curled tail, which she had also noted in other feral cats in northern California.  This genetic mutation seems to have no ill health effects associated with it.  The cats with curled tails were bred with Ragdoll cats and American Shorthair cats.  In 2005 The International Cat Association, gave this new breed “Registration Only” status. The Oriental Shorthair is a breed of domestic cat that is closely related to the Siamese.  It maintains the modern Siamese head and body type but appears in a wide range of coat colors and patterns.  Like the Siamese, Orientals have almond-shaped eyes, a triangular head shape, large ears, and an elongated, slender, and muscular body.  Their personalities are also very similar.  Orientals are social, intelligent, and many are rather vocal.  They often remain playful into adulthood, with many enjoying playing fetch.  Despite their slender appearance, they are athletic and can leap into high places.  They prefer to live in pairs or groups and also seek human interaction.  Unlike the breed's blue-eyed forebear, Orientals are usually green-eyed.  The Oriental Longhair differs only with respect to coat length. The Donskoy is a hairless cat breed of Russian origin.  This breed started in 1987 with the discovery of a hairless cat in the Russian city of Rostov-on-Don by cat breeder Elena Kovaleva.  It is not related to the better known hairless breed of cat the Sphynx, also known as the Canadian hairless, whose characteristic hairlessness is caused by a recessive gene, whereas the Don hairlessness is caused by a dominant gene. The Oriental Longhair is a breed of domestic cat.  It is closely related to the Oriental Shorthair. The Asian Semi-Longhair is a cat breed similar to the Asian Shorthair except it has semi-long fur.  The breed is also known by the name Tiffanie or Tiffany.  It is recognized in any of the Asian Shorthair or Burmese colors and patterns.  Like the Asian Shorthair, the breed was developed in Britain and is not currently recognized by any U.S. Registries.  It has full recognition in the GCCF.  It is related to, and in some registries distinct from, the Chantilly-Tiffany or Foreign Longhair, the North American variant. The Serengeti is a breed of domestic cat, first developed by crossing a Bengal (domestic and wild hybrid) and an Oriental Shorthair.  Recognized and registered by The International Cat Association (TICA), no other first generation crosses can be registered as Serengeti.  From the Bengal × Oriental cross came the first foundation Serengeti.  Breeders then worked with the cat to produce a cat that resembles the breed profile set by TICA.
