The Siamese cat is one of the first distinctly recognized breeds of domestic cat.

This breed is famous for its unique appearance and social personality. They are known for a colorpoint coat and bright, blue, almond-shaped eyes. Most modern Siamese have an elongated, tubular, and muscular body. Their heads are triangular, which creates a wedge shape from the nose to the ears.

These cats are often described as extroverts because they are very social. They tend to bond strongly with a single person. They are also considered more diurnal, meaning they are more active during the day. Some experts note they are less likely to hunt than other cats.

The distinctive colorpoint pattern is caused by a specific biological process. This pattern is a form of partial albinism called acromelanism. It is caused by a mutation in tyrosinase, which is an enzyme used to make melanin. Melanin is the substance that gives hair and skin its color. In Siamese cats, this tyrosinase enzyme is heat-sensitive. This means the enzyme fails to work at normal body temperatures. However, it becomes active in cooler areas of the skin, specifically below 33 degrees Celsius.

These cooler areas include the face, ears, tail, and legs. This happens because airflow through the sinuses helps cool the face.

Because of this heat sensitivity, Siamese kittens are born cream or white. They develop their dark points during their first few months of life. As the cats grow older, they actually tend to darken. Their coat color can also change based on their environment. Adult Siamese living in warm climates often have lighter coats than those in cool climates.

The breed originally had mostly black points, which are called "seal" points. Over time, breeders developed other colors through specific programs. These include blue, chocolate, lilac, cinnamon, fawn, red, cream, and apricot. These colors can appear in solid, tabby, tortoiseshell, or even silver tabby patterns.

The history of the Siamese cat stretches back to the Ayutthaya Kingdom.

This kingdom existed from 1351 to 1767 AD. Descriptions of the Wichianmat, the original landrace cat, appear in ancient manuscripts called the Tamra Maew. These "Cat-Book Poems" are kept in the National Library of Thailand and other locations. A Thai legend says the King of Burma, Hsinbyushin, read these poems. He believed the cats were as rare as gold. He ordered his army to bring the cats back to Myanmar as treasures.

In the West, the breed's development began in the late 19th century. In 1878, US President Rutherford B. Hayes received the first documented Siamese in the United States. The cat was named "Siam" and arrived from Bangkok. In 1884, Edward Blencowe Gould brought a breeding pair named Pho and Mia to Britain.

Their kittens were shown at London's Crystal Palace Show in 1885. By 1886, more cats were imported to the UK by Eva Forestier Walker and her sister. These early imports were known in Britain as the "Royal Cat of Siam."

Over the last century, the physical look of the breed has changed significantly. In the 1950s and 1960s, breeders began to favor a more slender appearance. They used selective breeding to create cats with longer, fine-boned bodies. This resulted in the modern show-style Siamese, which has a very thin tail and large, wide-set ears. By the mid-1980s, the rounder, "old-style" cats were separated into a new breed. This breed is now officially called the Thai cat.

Both the Siamese and the Thai cat descend from the same Wichianmat ancestors.

The Siamese breed has also been used as foundation stock for many other cats. By crossbreeding them, breeders created the Oriental and the Colourpoint Shorthair.

When crossed with Persians, they produced the long-haired Himalayan. The long-haired Siamese is also recognized as the Balinese.

Siamese features also appear in hair-mutation breeds like the Cornish Rex, Sphynx, and Peterbald. Today, the breed remains popular, ranking 17th out of 54 breeds in 2024 FIFe statistics. This means they made up 1% of all registered kittens, or about 929 cats, that year.
