Siamese

Lore & Background

The Siamese cat is a breed with a distinctive colourpoint coat, which results from a temperature-sensitive type of albinism. Its defining characteristics include blue almond-shaped eyes, a triangular wedged head shape, large wide-set ears, and an elongated, slender, and muscular body. The breed exhibits various colours of point colouration. The Siamese is one of the first distinctly recognised breeds of domestic cat, selectively bred since the end of the 19th century from the Wichianmat landrace, a variety of cat native to Thailand, formerly known as Siam. The breed was highly popular in Europe and North America during the 19th century. Around the 1950s, a modern-style body with slender and angular features became the preferred type among enthusiasts. From the 1980s onward, traditional "old-style" cats with a rounder build began to be officially separated from the modern Siamese breed and were re-established by multiple registries as the separate Thai cat breed. The Siamese has been used as foundation stock for several new cat breeds, including the Oriental, Colourpoint Shorthair, Himalayan, Balinese, Cornish Rex, Sphynx, and Peterbald.

Reader's Guide

The Siamese cat is significant as one of the earliest standardised cat breeds, serving as foundation stock for several other breeds, including the Oriental, Colourpoint Shorthair, Himalayan, Balinese, Cornish Rex, Sphynx, and Peterbald. Its distinctive colourpoint pattern results from a temperature-sensitive albinism mutation. The breed split into two types from the 1980s onward: the modern show-style Siamese with an elongated, angular body, and the traditional old-style, now recognised as the separate Thai breed by registries such as TICA and WCF. Its legacy includes influencing cat fancy standards and breeding practices worldwide.

Did You Know?

• The Siamese cat's colourpoint pattern results from a heat-sensitive tyrosinase enzyme that only produces pigment in cooler body areas.
• Siamese kittens are born cream to white and develop visible points within the first few months of life.
• Although the Siamese arrived in the West in the late 1870s/1880s, it remained extremely rare and did not become widely popular until the 20th century.
• Foundation stock cats from Thailand sometimes had kinked tails, a trait largely eradicated by breeders around the 1950s.

Ancient Roots in the Kingdom of Siam

During that era, scribes composed a collection of poems known as the Tamra Maew, or the Cat-Book Poems, which included vivid descriptions and illustrations of the Wichianmat, a colourpointed landrace native to the region. Over a dozen of these ancient manuscripts survive today, housed in the National Library of Thailand, the British Library, and the National Library of Australia. According to Thai legend, the Burmese king Hsinbyushin read the Wichianmat poem, which described these cats as rarer than gold and a source of wealth to their owners. He allegedly ordered his soldiers to collect every such cat and transport them to Burma alongside other plundered treasures. Whether or not that legend holds up to scrutiny, the Wichianmat landrace clearly existed as a distinct variety long before Western breeders ever encountered it.

Arrival in the West and the Founding of the Breed

The pointed cat that would become the Siamese first caught Western attention in the late 1870s. Hayes received a cat named Siam, sent from Bangkok to the American consul, marking the first documented Siamese in the United States. Tragically, all three kittens died shortly after the show, with no cause recorded. The following year, Eva Forestier Walker and her sister Ada imported four more Siamese cats to Britain. These animals were long-bodied with rounded heads, wedge-shaped muzzles, and large ears, and their pointed coat pattern was entirely novel to Western eyes. Over the subsequent years, a small trickle of additional imports formed the foundation stock for the entire British breed, and today, thanks to digitised registry records, most modern Siamese pedigrees can be traced back to these original cats.

The Great Style Split: Siamese versus Thai

For much of its early history in the West, the Siamese cat was a relatively moderate animal—long-bodied but not extreme, with rounded heads and proportionate features. That changed dramatically in the 1950s and 1960s, when breeders and show judges began favouring an increasingly slender, angular look. Through successive generations of selective breeding, the show Siamese was pushed toward an extreme: a lean, tubular body, very long and slender legs, a thin tail tapering to a point, a long wedge-shaped head, and enormous wide-set ears. By the mid-1980s, cats of the older, rounder traditional style had largely vanished from cat shows. However, a handful of breeders, particularly in the United Kingdom, refused to let that look disappear. They continued breeding and registering the rounder-built cats, and by the 1980s multiple cat registries, including TICA and the World Cat Federation, formally re-established the traditional type as a separate breed called the Thai. Today, the modern Siamese and the Thai are effectively distinct sub-breeds, both descended from the same Wichianmat ancestors but with few or no recent ancestors in common.

Foundation Stock for a Constellation of New Breeds

The Siamese cat's influence extends far beyond its own breed. Because of its distinctive colourpoint coat, caused by a temperature-sensitive form of albinism, the Siamese has served as foundation stock for numerous other cat breeds. Crossbreeding Siamese cats with other varieties produced the Oriental and the Colourpoint Shorthair, both developed to expand the range of coat patterns available in the Siamese body type. A cross with the Persian yielded the Himalayan, a long-haired colourpoint cat. The long-haired Siamese is recognised internationally as the Balinese. The breed's genetic contribution also reached into the world of hair-mutation cats: Siamese features were introduced into the Cornish Rex, the Sphynx, and the Peterbald through crossbreeding programmes. In every case, the Siamese brought its characteristic pointed colouration, blue almond-shaped eyes, and slender build to the mix. This makes the breed one of the most genetically influential in the entire domestic cat world, with its DNA embedded in a remarkable diversity of modern pedigreed cats.

Common Misconceptions (Editorial)

A common misconception is that the Siamese cat is a modern breed from the West; in fact, it is bred from the Wichianmat landrace native to Thailand and has been selectively bred since the end of the 19th century. Another misconception is that the breed’s distinctive colourpoint coat is present at birth, but Siamese kittens are born cream to white and develop visible points within the first few months of life. Some people also believe that kinked tails are a standard trait of the Siamese, whereas foundation stock cats from Thailand sometimes had kinked tails, a trait largely eradicated by breeders around the 1950s.

Why It Matters (Editorial)

The Siamese cat endures as one of the most recognisable and historically significant domestic breeds, embodying both ancient heritage and modern selective breeding. Its unique colourpoint pattern and dramatic appearance have captivated cat fanciers for over a century, while its roots in Thailand remind us that many beloved pets have deep cultural and geographic origins worth preserving.
