Persian

About the breed

The Persian is one of the most recognizable cat breeds in the world, known for its extremely long, dense coat and completely flattened, round face. That extreme head shape also carries real health considerations that shouldn't be glossed over: labored breathing, chronic eye tearing, crowded teeth, and a genetic kidney disease (PKD1) that was, for decades, the breed's leading hereditary condition. On the other hand, the Persian is an exceptionally calm, quiet, home-loving cat that needs very little exercise - but a great deal of daily coat care in return.

Origin and the move to Britain

The breed's ancestors were longhaired cats from Persia/Iran and Afghanistan that reached Europe as early as the 17th century via Italian traders. The modern breed, however, was largely shaped by British breeders: Persians dominated the first cat show in London in 1871, and by 1906 they were one of the six founding breeds of the American Cat Fanciers' Association (CFA).

From a natural face to an extreme type

The earliest Persians had a fairly ordinary muzzle. A spontaneous mutation in the late 1950s produced the so-called 'peke-faced' type with an extremely flattened face; it was briefly recognized as a separate variety but abandoned by the mid-1990s due to health problems. Its legacy remained, though: during the 1970s and 1980s American breeders began deliberately emphasizing an extreme head type ('ultra-typing'), and in 2007 the CFA standard itself came to call for the forehead, nose and chin to align vertically. Today both extremely flat-faced show-type Persians and milder 'traditional' or doll-face Persians exist side by side.

Flat face and breathing

The dramatically shortened muzzle leaves many Persians with narrowed nostrils and abnormally positioned nasal turbinates - the latter found in roughly a fifth of brachycephalic cats examined in one study. The result is noisier breathing, snoring, quicker fatigue during exertion, and poorer heat tolerance. These problems are generally milder than in the most extreme brachycephalic dog breeds, but they are real and documented, and more severe cases sometimes need surgery to widen the nostrils.

Watery eyes

The flattened face shortens and kinks the tear ducts, while the shallow eye socket leaves more of the eyeball exposed - one study measured almost four times more eyeball protrusion in Persians than in ordinary domestic cats. The result is chronic tearing (epiphora) that can irritate the skin beneath the eyes, along with a higher risk of corneal ulcers, since Persians also have reduced corneal sensitivity. Regular cleaning around the eyes is therefore part of everyday care.

Teeth

The shortened jaw often leaves too little room for all the teeth, so misaligned teeth are common in Persians - one study found an average of two malpositioned teeth per cat, versus almost none in domestic shorthairs. This raises the risk of plaque buildup and gum disease.

PKD1 and genetic testing

Polycystic kidney disease (PKD1) was once so common in Persians that it was nicknamed 'Persian cat disease' - in the 1990s and early 2000s, ultrasound surveys found anywhere from 33% to nearly 50% of cats affected. Discovery of the PKD1 gene mutation made a precise DNA test possible, identifying carriers even in kittens. Thanks to systematic testing in breeding programs, prevalence in tested populations has dropped sharply - one Brazilian study, for example, recorded a fall from 33% to 5% within less than a decade - though the mutation is still not rare in untested lines. Kitten buyers should always ask whether the parents have been DNA tested.

Daily coat care

The long, dense undercoat needs daily combing with a metal comb, or it quickly mats, especially behind the ears, under the arms and around the hindquarters. Bathing roughly every four to six weeks is also recommended, and mats must be fully removed beforehand since water only tightens them further. Given the amount of care involved, many owners rely on professional grooming and bathing.

Calm temperament, low activity

The Persian is known for its placid, quiet nature and low need for exercise - it would rather sit in a lap than chase toys around the house. That calmness makes it ideal for apartments and quiet households, but it also means watching body weight carefully, since extra kilograms add further strain to breathing that is already compromised.
