Answer the following question: Information: - North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea. - 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. - Johann Christian Daniel von Schreber (17 January 1739 in Weiensee, Thuringia 10 December 1810 in Erlangen), often styled J.C.D. von Schreber, was a German naturalist. - The domestic cat is a small, typically furry, carnivorous mammal. They are often called house cats when kept as indoor pets or simply cats when there is no need to distinguish them from other felids and felines. Cats are often valued by humans for companionship and for their ability to hunt vermin. There are more than 70 cat breeds, though different associations proclaim different numbers according to their standards. - The International Cat Association (TICA) is the world's largest genetic cat registry. Originally a North American organization, it now has a worldwide presence. The organization has a genetic registry for pedigreed and household pet cats and is one of the world's largest sanctioning bodies for cat shows. - 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 . Created by Karen Sausman of Kingsmark Cattery in California in 1994 , the breed is still in the development stages , but the ultimate aim is to produce a cat that looks similar to a serval , without using any recent wild cat blood . ( Bengal cats originate from hybridization of leopard cats and domestic cats . Most Bengal cats used in Serengeti breeding programs are many generations removed from these origins and possess few genetic contributions of the wild forbear except alleles affecting coat color . ) Serengetis are spotted cats , with long legs and very large , round tipped ears . They have a long neck which blends with the base of the skull without tapering . Males are generally slightly larger and heavier than females and can weigh between 10 to 15 lbs ; females generally weigh between 8 and 12 lbs. Because the Bengal stock is a hybrid cat , the Serengeti is also classified as a hybrid . They are recognized by TICA in tabby , ebony silver , ebony smoke and solid black . A group of breeders in the UK are currently working towards getting TICA to also recognise the snow spotted ( aka lynx - point ) variety . The tabby is known as the brown - spotted in the UK . However spots can be black or dark brown on a tan , light beige or gold background . The silver has black spots on a silver background . Ghost spotting can sometimes be seen on the solid black version . - The serval ("Leptailurus serval"), also known as the tierboskat, is a wild cat found in Africa. It is the sole member of the genus "Leptailurus" and was first described by German naturalist Johann Christian Daniel von Schreber in 1776. Eighteen subspecies are recognised. The serval is a slender, medium-sized cat that stands at the shoulder and weighs . It is characterised by a small head, large ears, a golden-yellow to buff coat spotted and striped with black, and a short, black-tipped tail. The serval has the longest legs of any cat relative to its body size. - In biological classification, subspecies (abbreviated "subsp." or "ssp."; "plural": "subspecies") is either a taxonomic rank subordinate to species, or a taxonomic unit in that rank. A subspecies cannot be recognized independently: a species will either be recognized as having no subspecies at all or at least two (including any that are extinct). - A cat show is a judged event where the owners of cats compete to win titles in various cat registering organizations by entering their cats to be judged after a breed standard. Both pedigreed and companion (or moggy) cats are admissible, although the rules differ from organization to organization. Cats are compared to a breed standard, and the owners of those judged to be closest to it are awarded a prize. Moggy's are judged based on their temperament. Often, at the end of the year, all of the points accrued at various shows are added up and more national and regional titles are awarded. - The Oriental Longhair is a breed of domestic cat. It is closely related to the Oriental Shorthair. - A cat registry or cat breed registry, also known as a cat fancier organisation, cattery federation, or cat breeders' association, is an organisation that registers domestic cats (usually purebred) of many breeds, for exhibition and for breeding lineage tracking purposes. A cat registry stores the pedigrees (genealogies) of cats, cattery names, and other details of cats; studbooks (lists of authorised studs of recognised breeds), breed descriptions, and the formal breed standards (a.k.a. standards of points or SoP); lists of judges qualified to judge at shows run by or affiliated with that registry; and sometimes other information. A cat registry is not the same as a breed club or breed society (these are specific-breed organisations that may be affiliated with one or more registries with whom they have lodged breed standards in order to be able to exhibit under the auspices of that registry). Cat registries each have their own rules and usually also organise or license (sanction) cat shows. The show procedures vary widely, and awards won in one registry are not normally recognised by another. Some registries only serve breeders, while others are oriented toward pet owners and provide individual as well as cattery memberships, while yet others are federations only deal with breed clubs or even other registries as intermediaries between the organisation and breeders. - A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. What entity does 'serengeti cat' has the relation 'instance of' with?
Answer:
cat breed
