The selective breeding carried out by breeders has allowed the development of a wide variety of coat colors, but has also led to the creation of increasingly flat-faced Persians. Favored by fanciers, this head structure can bring with it a number of health problems. Like the case with the Siamese breed, there has been efforts by some breeders to developed the older type cats with a more pronounced muzzle, which is more popular with the general public. The hereditary polycystic kidney disease is prevalent in the breed, affecting almost half the population in some countries.
The placid and homely nature of the Persian confers a propensity for apartment living. It has been the most popular breed in the United States for many years but its popularity has seen a decline in Britain and France.
Origin
In general, it's not clear when longhaired cats first appeared, as there are no African Wildcats, who are believed to be ancestors of domesticated cats, with long fur. There were claims in the 1800s that the gene responsible for long hair was introduced through hybridization with the Pallas cat, however, research in the early 1900s refutes this theory.
A doll face silver Persian
The first documented ancestors of the Persian were imported from Khorasan, Persia into Italy in 1620 by Pietro della Valle, and from Angora, Turkey into France by Nicholas-Claude Fabri de Peiresc at around the same time. The Khorasan cats were grey coated while those from Angora were white. From France, they soon reached Britain. Longhaired cats were also imported to Europe from Afghanistan, Burma, China and Russia. Interbreeding of the various types were common especially between Angoras and Persians.
Persians and Angoras
The Persian was presented at the first cat show in Crystal Palace, London in 1871. As specimens closer to the Persian conformation became the more popular types, attempts were made to differentiate it from the Angora. The first breed standards (then known as points of excellence) was issued in 1889 by Harrison Weir, the creater of the first cat show. He stated that the Persian differed from the Angora in the tail being longer, hair more full and coarse at the end and head larger, with less pointed ears. Not all cat fanciers agree with the distinction of the two types and in the 1903 book "The Book of the Cat" Francis Simpson states that "the distinctions, apparently with hardly any difference, between Angoras and Persians are of so fine a nature that I must be pardoned if I ignore the class of cat commonly called Angora".
Dorothy Bevill Champion lays out the difference between the two types in the 1909 Everybody's Cat Book:
The Exotic Shorthair is similar to the Persian in temperament and type, with the exception of its short, dense coat.
Our pedigree imported long-hairs of to-day are undoubtedly a cross of the Angora and Persian ; the latter possesses a rounder head than the former, also the coat is of quite a different quality. The coat of the Persian consists of a woolly under coat and a long, hairy outer coat. In summer it loses all the thick underwool, and only the long hair remains. The hair is also somewhat shorter on the shoulders and upper part of the hind legs.
Now, the Angora has a very different coat, consisting of long, soft hair, hanging in locks, inclining to a slight curl or wave on the under parts of the body. The hair is also much longer on the shoulders and hind legs than the Persian, this being a great improvement; but the Angora fails to the Persian in head, the former having a more wedge-shaped head, whereas that of the modern Persian excels in roundness.
Of course. Angoras and Persians have been constantly crossed, with a decided improvement to each breed; but the long-haired cat of to-day is decidedly more Persian-bred than Angora.
Champion lamented the lack of distinction among various long-haired types by English fanciers, who in 1887, decided to group them under the umbrella term "Long-haired Cats".
The Himalayan or Colorpoint Longhair was created by crossing the Persian with the Siamese. This crossing also introduced the chocolate and lilac color into solid colored Persians.
Peke-face and ultra-typing
Perhaps in recent times there has been a tendency to over-accentuate this type of short face, with the result that a few of the cats seen at shows have faces which present a peke-like appearance. This is a type of face which is definitely recognized in the United States, and helps to form a special group within the show classification for the [Persian] breed. There are certainly disadvantages when the face has become too short, for this exaggeration of type is inclined to produce a deformity of the tear ducts, and running eyes may be the result. A cat with running eyes will never look at its best because in time the fur on each side of the nose becomes stained, and thus detracts from the general appearance [...] The nose should be short, but perhaps a plea may be made here that the nose is better if it is not too short and at the same time uptilted. A nose of this type creates an impression of grotesqueness which is not really attractive, and there is always a danger of running eyes
In the UK, the standard was changed by the Governing Council of the Cat Fancy in the 1990s to disqualify Persians with the "upper edge of the nose leather above the lower edge of the eye" from Certificates or First Prizes in Kitten Open Classes.
While ultra-typed cats do better in the show ring, the public seems to prefer to less extreme older "doll face" types.
Himalayan
In 1950, the Siamese was crossed with the Persian to create a breed with the body type of the Persian but colorpoint pattern of the Siamese. It was named Himalayan, after other colorpoint animals such as the Himalayan rabbit. In the UK the breed was recognized as the Colorpoint Longhair. The Himalayan stood as a separate breed in the US until 1984, when the CFA merged it with the Persian, to the objection of the breed councils of both breeds. Some Persian breeders were unhappy with the introduction of this "hybrid" into their "pure" Persian lines.
The CFA set up the registration for Himalayans in a way that breeders would be able to discern a Persian with Himalayan ancestry just by looking at the pedigree registration number. This was to make it easy for breeders who do not want Himalayan blood in their breeding lines to avoid individuals who, while not necessarily exhibiting the colorpoint pattern, may be carrying the point coloration gene recessively. Persians with Himalayan ancestry has registration numbers starting with 3 and are commonly referred to by breeders as colorpoint carriers (CPC) or 3000-series cats, although not all will actually carry the recessive gene. The Himalayan is also the source for the chocolate and lilac color in solid Persians.
Exotic Shorthair
A Persian with a visible muzzle in contrast with a Persian with its forehead, nose and chin in vertical alignment, as called for by CFA's 2007 breed standard. As the muzzle shortens, the nose is pushed up between the eyes. UK standards penalizes Persians , whose nose leather extends above the bottom edge of the eye.
Popularity
The Persian is the most popular breed of pedigree cats in the United States. In the UK, registration numbers have dwindled since the early 1990s and the Persian lost its top spot to the British Shorthair in 2001. As of 2008, it was the 5th most popular breed, behind the British Shorthair, Siamese and Bengal. In France, the Persian is the only breed whose registration declined between 2003 and 2007, dropping by more than a quarter.
Characteristics
A show-quality Persian has an extremely long and thick coat, short legs, a wide head with the ears set far apart, large eyes, and an extremely shortened muzzle. The breed was originally established with a short muzzle, but over time, this characteristic has become extremely exaggerated, particularly in North America. Persian cats can have any color or markings including pointed, golden, tortoiseshell, blue, and tabby.
The Persian is generally described as a quiet cat. Homely and placid, it adapts well to apartment life. Himalayans tend to be more active due to the influence of the Siamese. One study compared cat owners' perception of their cats and Persians rated higher than non-pedigree cats on closeness and affection to owners, friendliness towards strangers, cleanliness, predictability, vocalization and fussiness over food.
