The British Shorthair is the pedigree version of the traditional British domestic cat, with a distinctively stocky body, thick coat, and broad face. The most familiar colour variant is the "British Blue", with a solid grey-blue coat, pineapple eyes, and a medium-sized tail. The breed has also been bred in a wide range of other colours and patterns, including tabby and colourpoint.
The Siamese cat is one of the first distinctly recognised breeds of Asian cat. It derives from the Wichianmat landrace. The Siamese cat is one of several varieties of cats native to Thailand. The original Siamese became one of the most popular breeds in Europe and North America in the 19th century. Siamese cats have a distinctive colourpoint coat, resulting from a temperature-sensitive type of albinism.
The Australian Mist is a breed of cat developed in Australia. It is a cross between the Abyssinian cat, the Burmese cat, and the Australian Tabby cat. The Australian Mist has a distinct and unique coat pattern hence the name.
The Turkish Van is a semi-long-haired, standardised breed of domestic cat, which was developed in the United Kingdom from a selection of cats obtained from various cities of modern Turkey, especially southeast Turkey. The breed is rare, is one of the larger breeds, and is distinguished by the Van pattern, where the colour is restricted to the head and the tail, and the rest of the cat is white; this is due to the expression of the piebald white spotting gene, a type of partial leucism. A Turkish Van may have blue or amber eyes, or be odd-eyed.
The Maine Coon is a large domesticated cat breed. One of the oldest natural breeds in North America, the breed originated in the U.S. state of Maine, where it is the official state cat.
The Burmese cat is a breed of domestic cat, originating in Burma, believed to have its roots near the Thai-Burma border and developed in the United States and Britain.
Cat coat genetics determine the coloration, pattern, length, and texture of feline fur. The variations among cat coats are physical properties and should not be confused with cat breeds. A cat may display the coat of a certain breed without actually being that breed. For example, a Neva Masquerade could wear point coloration, the stereotypical coat of a Siamese.
The Siberian is a centuries-old landrace of domestic cat in Russia, and recently developed as a formal breed with standards promulgated the world over since the late-1980s. Since 2006, the breed is recognised for registry and championship status with all major cat registries.
The Snowshoe is a rare breed of domestic cat originating in the United States of America in the 1960s. The Snowshoe is a short-haired bicolour colourpoint breed. Snowshoes were first produced when a Siamese breeder's cat gave birth to three kittens with white feet. The breeder, Dorothy Hinds-Daugherty, then began a breeding program to produce what were originally called "Silver Laces", crossing the strangely marked Siamese cats with bicolour American Shorthair cats and other breeds. Despite having existed for 45 years, Snowshoes are rare due to the difficulty of reproducing the correct coat markings.
The Neva Masquerade is a breed or sub-breed of long-haired domestic cat, which originates in Russia. It is the sister breed or colourpoint variant of the Siberian cat, a centuries-old Russian landrace. The colourpoint markings are the result of a colourpoint gene originally found in Siamese cats. The Neva Masquerade is believed to be derived from crossing the Siberian cat with Asian colourpoint cats, such as the Siamese or Thai landrace, or possibly cats related to those, such as the colourpointed Persian cats. Some cat registries may classify the Neva Masquerade as a colourpoint variety or sub-breed of the Siberian cat, while others consider it to be a separate sister breed. Regardless of its classification, all Neva Masquerade cats are selectively bred and pedigreed today in all major cat fancier and breeder organisations under the Siberian (Forest) cat or Neva Masquerade. This means that all Neva Masquerade cats are purebred cats with a formally registered ancestry.
A tabby cat, or simply tabby, is any domestic cat with a distinctive M-shaped marking on its forehead, stripes by its eyes and across its cheeks, along its back, around its legs and tail, and characteristic striped, dotted, lined, flecked, banded, or swirled patterns on the body: neck, shoulders, sides, flanks, chest, and abdomen. The four known distinct patterns, each having a sound genetic explanation, are the mackerel, classic or blotched, ticked, and spotted tabby patterns.
An odd-eyed cat has one blue eye and one eye either green, yellow, amber, or brown. This is a feline form of complete heterochromia, a condition that occurs in some other animals, including humans. There is also sectoral (partial) heterochromia, where two different colours occur within the same iris. The condition most commonly affects solid white cats, but may be found in cats of any coat colour.
The Asian or Asian group, is a cat breed similar to the European Burmese but in a range of different coat colours and patterns. Long-haired Asians of all varieties are called Tiffanies. Asians are grouped in section 5 (Burmese) by the Governing Council of the Cat Fancy (GCCF).
An Oriental bicolour is any cat of Oriental type, either long-haired or short-haired and in any pattern including colourpoint, which has white areas on its coat caused by the white spotting gene. In most cat fancier and breeder organisations, Oriental bicolours do not constitute a standardised breed, but a coat pattern variant of the breed of their foundation stock. One breed registry is an exception, the UK-based Governing Council of the Cat Fancy (GCCF), which has defined them as a separate breed named Oriental Bicolour (capitalised).
Acromelanism is a genetic condition that results in pigmentation being affected by temperature. It results in point coloration where the extremities of an animal are a different colour to the rest of the body. It is commonly known for the coloration of Siamese and related breeds of cat, but can be found in many other species including dogs, rabbits, rats, mice, guinea pigs, minks, and gerbils. It is a specific type of point coloration.
Tortoiseshell is a cat coat coloring named for its similarity to tortoiseshell pattern. Like tortoiseshell-and-white or calico cats, tortoiseshell cats are almost exclusively female. Male tortoiseshells are rare and are usually sterile.
Colours of the Syrian hamster can be described in three ways: as "self", "agouti" or "combinations". Self colours are a consistent coat colour with the same colour topcoat and undercoat. Agouti hamsters have a ticked coat, where each individual fur is banded in different colours. Agouti hamsters also have "agouti markings" which consist of dark cheek markings, a dark marking on the head, and a light underbelly. Combinations are produced when two self or agouti colours are present.
The Abyssinian is a breed of cat with a distinctive "ticked" tabby coat, in which individual hairs are banded with different colours. They are also known simply as Abys.
The Persian cat, also known as the Persian Longhair, is a long-haired breed of cat characterised by a round face and short muzzle. The first documented ancestors of Persian cats might have been imported into Italy from Khorasan as early as around 1620, however, this has not been proven. Instead, there is stronger evidence for a longhaired cat breed being exported from Iran/Persia from the 19th century onwards. Persian cats have been widely recognised by the North-West European cat fancy since the 19th century, and after World War II by breeders from North America, Australia and New Zealand. Some cat fancier organisations' breed standards subsume the Himalayan and Exotic Shorthair as variants of this breed, while others generally treat them as separate breeds.
Dogs have a wide range of coat colors, patterns, textures and lengths. Dog coat color is governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog. Dogs have about 19,000 genes in their genome but only a handful affect the physical variations in their coats. Most genes come in pairs, one being from the dog's mother and one being from its father. Genes of interest have more than one expression of an allele. Usually only one, or a small number of alleles exist for each gene. In any one gene locus a dog will either be homozygous where the gene is made of two identical alleles or heterozygous where the gene is made of two different alleles.
