Persian
A deep dive into the Persian cat's history, genetics, and the critical health differences between the traditional and modern flat-faced types.
The Persian cat is a long-haired breed defined by a round face and a short, but not flat, muzzle in its traditional form, though modern breeding has created a flat-faced variant that causes significant health issues. The breed's history involves complex origins from the Near East, genetic shifts toward European populations, and a controversial 20th-century trend toward extreme facial features that compromised the animal's ability to breathe and eat.
Origin and the "Persian" name
The exact time long-haired cats first appeared is unclear, as no long-haired specimens of the African wildcat, the ancestor of the domestic cat, are known. The first documented ancestors might have been imported into Italy from Khorasan (Eastern Iran or Western Afghanistan) around 1620 by Pietro Della Valle, though this is not fully proven. Stronger evidence exists for a longhaired breed being exported from Afghanistan and Iran/Persia from the 19th century onwards. Despite the name, Persian-speakers are not documented to refer to any breed of cat as "Persian cat" or gorba-ye pârsi; variations like gorbe-ye borāq appear in 19th and 20th-century dictionaries instead.
Historical accounts from 1815 and 1839 suggest that the cats exported to Europe were often bred in Kabul and parts of Toorkistan, not Persia itself. British observers noted that the "Persian" name was applied for marketing purposes, as very few were found in Persia and none were exported from there. By the late 19th century, these long-haired cats were being traded in caravans to India and Europe, eventually becoming widely recognized by the North-West European cat fancy.
Genetic reality and European roots
Modern genetic research indicates that present-day Persian cats are related not to cat breeds from the Near East, but to those from Western Europe. Researchers state that while the early Persian cat may have originated from Persia, the modern Persian cat has lost its phylogeographical signature. The modern breed is genetically closest related to the British Shorthair, Chartreux, and American Shorthair. The Exotic Shorthair, a breed developed in the late 1950s, was created by outcrossing Persian cats with American Shorthairs.
Traditional versus modern facial structure
The traditional Persian, sometimes called the doll-face or moon-face, is the original phenotype characterized by a round face and a petite muzzle that is not flat or smashed in. This structure enables the cat to breathe without difficulties. In contrast, the short flat nose was created in the US through in-breeding, a development that causes breathing difficulties in the breed. This flat-faced type is often referred to as the "peke-face" or "ultra-type" Persian.
In the late 1950s, a spontaneous mutation in red tabby Persians gave rise to the peke-faced variant. While initially registered as a distinct breed, it fell out of favor by the mid-1990s due to serious health issues, with only 98 registered between 1958 and 1995. Despite this, breeders continued to select for the look, leading to extreme- or ultra-typing. The Persian breed standard originally called for a short, cobby body and a round appearance, but it was not until the late 1980s that standards were changed to limit the development of the extreme appearance.
Health implications of extreme breeding
The selective breeding that created the flat-faced Persian has brought with it several health problems. A nose that is too short creates an impression of grotesqueness and is inclined to produce a deformity of the tear ducts, resulting in running eyes. This condition causes the fur on each side of the nose to become stained over time, detracting from the cat's appearance. Furthermore, the extreme facial structure can interfere with the cat's ability to eat and breathe properly.
Hereditary polycystic kidney disease (PKD) is also prevalent in the breed, affecting almost half of the population in some countries. As is the case with the Siamese breed, there have been efforts by some breeders to preserve the older type of cat, the Traditional Persian, which has a more pronounced muzzle and avoids the respiratory and ocular issues associated with the flat face.
Popularity and breed recognition
Persian cats have been widely recognized by cat fancier organizations since the 19th century. In 2021, they were ranked as the fourth-most popular cat breed in the world according to the Cat Fanciers' Association (CFA). Some organizations subsume the Himalayan and Exotic Shorthair as variants of the Persian breed, while others treat them as separate breeds. The TICA standard is more general and does not specify a flattened face, allowing for the preservation of the traditional phenotype in some registries.
Coat characteristics and care
Persian coats consist of a woolly undercoat and a long, hairy outer coat. The coat loses all the thick underwool in the summer, leaving only the long hair. This seasonal shedding is distinct from the Angora, which has long, soft hair hanging in locks that incline to a slight curl. The Persian's hair on the shoulders and upper part of the hind legs is somewhat shorter than the Angora's, and the head is rounder. Regular grooming is essential to prevent matting, especially given the density of the coat.
