Domestic cat (Felis catus) |
The Birman, also called the "Sacred Cat of Burma", [1] is a domestic cat breed. The Birman is a long-haired, colour-pointed cat distinguished by a silky coat, deep blue eyes, and contrasting white "gloves" on each paw.
The breed name is derived from Birmanie, the French form of Burma. The breed was first recognised in 1925 in France.
No clear record of the breed's origin exists. They are most often claimed to have originated as the companions of temple priests in northern Burma in the Mount of Lugh. [1] Many stories exist of how the cats first came to France, including pairs of cats being given as a reward for helping defend a temple, or being smuggled out of Burma and Sweden by a Vanderbilt [ who? ]. [1] [2] Another pair of Birmans (or a pregnant female called Poupée de Maldapour) were said to have been stolen and later imported to France by Thadde Haddisch. [3] The first traces of historical Birmans go back to a Mme Leotardi [4] in Nice, France.
Birmans were almost wiped out as a breed during World War II. Only two cats were alive in Europe at the end of the war, a pair named Orloff and Xenia de Kaabaa, both belonging to Baudoin-Crevoisier. The foundation of the breed in postwar France were offspring of this pair. They had to be heavily outcrossed with long-hair breeds such as Persian and Siamese to rebuild the Birman breed. By the early 1950s, pure Birman litters were again being produced. The restored breed was recognized in Britain in 1965 and by the CFA in 1966. [5]
The first Birman cats were seal point. The blue point colour was introduced in 1959 using blue Persian lines. New colours were later added by English breeders including chocolate, red, and tabby/lynx points. [6] Birmans have also been used in the development of new breeds such as the Ragdoll. [7]
The Birman breed was first recognized in France by the Cat Club de France in 1925, then in England by the Governing Council of the Cat Fancy [8] (GCCF) in 1966 and in United States by the Cat Fanciers' Association [1] (CFA) in 1967. It was also recognized by the Canadian Cat Association (CCA) and the International Cat Association [9] (TICA) in 1979.
Birmans have a medium-sized, rectangular body with a broad face and distinct Roman nose. Their ears are ideally as wide on the base as they are tall and should be set as much on top of the head as on the side. The eyes are rounded and should be a deep sapphire blue. [10]
The Birman's fur is medium-long and should have a silky texture. Unlike a Persian or Himalayan, they have no undercoat, thus are much less prone to matting.[ citation needed ] Coat colour is always pointed, save for the contrasting pure white, symmetrical "gloves" on each paw that are the trademark of the breed. The white must involve all toes and in front must stop at the articulation or at the transition of toes to metacarpals. These gloves should extend noticeably further up the back of the leg (referred to as the "laces"), finishing with an inverted V extended half to three-fourths up the hock. Any other spot of white on the points is considered a serious fault. The base body colour is white to cream, with a wash of colour that corresponds to the points, but is much paler. [10]
Recognized point colours are seal, chocolate, red and the corresponding dilute varieties: blue, lilac and cream. [11] Tabby and tortie variations in seal, chocolate, blue or lilac are also allowed; other colours are in development. [10]
A 2008 study by Lipinski et al. found that the Birman has one of the lowest levels of genetic diversity of all the breeds studied. [12]
A study in the UK of veterinary records found the Birman to have a life expectancy of 14.39 years based on a sample of 38 cats, higher than the 11.74 average overall. [13]
Paltrinieri, Giraldi, Prolo, Scarpa, et al. (2017) [14] found that Birman cats have a high serum concentration of creatinine and symmetric dimethylarginine, but most Birman cats have higher concentrations of creatinine than SDMA. Creatinine is a creatine phosphate and is produced during metabolism of creatine, and is excreted through urination. SDMA is a methylated form of the amino acid arginine and is released during normal catabolisms of body proteins. Levels of creatinine and SDMA are found when Birman cats are tested for chronic kidney disease, for which they are at high risk. Birman cats are also at risk of developing feline infectious peritonitis; a disease that alters the renal function (creatinine levels in blood and urine) in the cats. [14] In a review of over 5,000 cases of urate urolithiasis the Birman was over-represented with an odds ratio of 6.77. [15]
Feline audiogenic reflex seizures (FARS), a recently discovered type of epilepsy in cats, is believed to be particularly common in Birman cats. [16]
Many Birman breeders follow the French tradition of assigning all kittens born in a particular year given names that begin with the same letter of the alphabet. Countries with breeders using this convention include Australia, Canada, France, New Zealand, the U.K., and the U.S. Kittens born in 2016 would start with 'N', and in 2017 'O', and so on. [1]
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 Sphynx cat also known as the Canadian Sphynx, is a breed of cat known for its lack of fur. Hairlessness in cats is a naturally occurring genetic mutation, and the Sphynx was developed through selective breeding of these animals, starting in the 1960s.
The Exotic Shorthair is a breed of cat developed as a short-haired version of the Persian. The Exotic is similar to the Persian in appearance with the exception of the short dense coat.
The Ocicat is an all-domestic breed of cat which resembles a wild cat but has no recent wild DNA in its gene pool. It is named for its resemblance to the ocelot. The breed was established from the Siamese and Abyssinian and later on American Shorthair would be added.
The Himalayan, is a breed or sub-breed of long-haired cat similar in type to the Persian, with the exception of its blue eyes and its point colouration, which were derived from crossing the Persian with the Siamese. Some registries may classify the Himalayan as a long-haired sub-breed of Siamese, or a colorpoint sub-breed of Persian. The World Cat Federation has merged them with the Colorpoint Shorthair and Javanese into a single breed, the Colorpoint.
The Somali cat is genetically similar to the Abyssinian cat. Due to inheriting 2 copies of the recessive gene for long hair, they have a characteristic luscious coat, unlike their cousin the Abyssinian.
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.
The Egyptian Mau is a small to medium-sized, short to medium-haired cat breed. They are one of the few naturally spotted breeds of domesticated cat. The spots of the Mau occur on only the tips of the hairs of its coat. It is considered a rare breed.
The Havana Brown was the result of a planned breeding between Siamese and domestic black cats, by a group of cat fanciers in England, in the 1950s. Early breeders introduced a Siamese type Russian Blue into their breeding. However, using current genetic testing, it is believed that almost none remain in the gene pool.
Tonkinese is a domestic cat breed produced by crossbreeding between the Siamese and Burmese. Members of the breed are distinguished by a pointed coat pattern in a variety of colors. In addition to the modified coat colors of the "mink" pattern, which is a dilution of the point color, the breed is now being shown in the foundation-like Siamese and Burmese colors: pointed with white and solid overall (sepia).
The Cat Fanciers' Association (CFA) was established in the United States in 1906. The CFA is currently the world's largest registry of pedigreed cats. Originally headquartered in Manasquan, New Jersey, the CFA moved to Alliance, Ohio in 2010. The association's stated mission is preserving and promoting pedigreed breeds of cats while also enhancing the well-being of all cats. CFA's first licensed cat shows were held in Buffalo, New York and Detroit, Michigan in 1906. The association today has a known presence in Europe, China, and Japan along with its well-established activity in the United States and Canada.
The Ragdoll is a breed of cat with a distinct colorpoint coat and blue eyes. Its morphology is large and weighty, and it has a semi-long and silky soft coat. American breeder Ann Baker developed Ragdolls in the 1960s. They are best known for their docile, placid temperament and affectionate nature. The name Ragdoll is derived from the tendency of individuals from the original breeding stock to go limp and relaxed when picked up. The breed is particularly popular in both the United Kingdom and the United States.
The American Shorthair (ASH) is a breed of domestic cat believed to be descended from European cats brought to North America by early settlers to protect valuable cargo from mice and rats. According to the Cat Fanciers' Association, it was the eighth most popular pedigreed cat in the world for 2020.
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 Chantilly-Tiffany or Chantilly/Tiffany, also known as the Chantilly or the Foreign Longhair, was a breed of domestic cat which originated in the late-1960s in North America. The Chantilly breed never got off the ground and has always been rare. It was near-extinction in the late-1980s and again in the late-2000s. Since 2015 the breed has been considered extinct with the passing and neutering of the last two cats of the Chantilly lineage, and with no intact Chantilly cats the inevitable resulting discontinuation of the breeding program.
The Colorpoint Shorthair is a variety of Siamese cat. The only major registries to recognise them are the Cat Fanciers' Association (CFA) and the World Cat Federation (WCF). This breed was established from breeding American Shorthairs with the Siamese to produce different point colors, beyond the four standard Siamese colors.
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.
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.
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 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.
