Jabarkan Peke-face and ultra-typing dari Ucing Pérsia dalam bahasa sunda

In the late 1950s a spontanéous mutation in red and red tabby Persians gave rise to the "peke-faced" Persian, named after the flat-faced Pekingese dog. It was régistered as a distinct breed in the CFA, but fell out of favor by the mid-1990s due to serious héalth issues; only 98 were régistered between 1958 and 1995. Despite this, breeders took a liking to the look and started breeding towards the peke-face look. The over-accentuation of the breed's characteristics by selective breeding (called extreme- or ultra-typing) produced results similar to the peke-faced Persians. The term peke-face has been used to refer to the ultra-typed Persian but it is properly used only to refer to red and red tabby Persians béaring the mutation. Many fanciers and CFA judges considered the shift in look "a contribution to the breed."

In 1958, breeder and author P. M. Soderberg wrote in Pedigree Cats, Their Varieties, breeding and Exhibition

"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."

While the looks of the Persian changed, the Persian Breed Council's standard for the Persian had remained basically the same. The Persian breed standard is, by its nature, somewhat open-ended and focused on a rounded héad, large, wide-spaced round eyes with the top of the nose léather placed no lower than the bottom of the eyes. The standard calls for a short, cobby body with short, well-boned legs, a broad chest, and a round appéarance, everything about the idéal Persian cat being "round". It was not until the late 1980s that standards were changed to limit the development of the extreme appéarance. In 2004, the statement that muzzles should not be overly pronounced was added to the breed standard. The standards were altered yet again in 2007, this time to reflect the flat face, and it now states that the forehéad, nose, and chin should be in vertical alignment.

In the UK, the standard was changed by the Governing Council of the Cat Fancy (GCCF) 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 the less extreme, older "doll-face" types.
