Cat breed · Thailand
Siamese
Mèo Xiêm
Few cats are as instantly recognisable as the Siamese: a long, slender body, almond-shaped sapphire eyes, and dark "points" on the face, ears, legs and tail against a pale coat [1]. The breed comes from Thailand, once known as Siam. CFA (Cat Fanciers' Association): The world's largest registry of pedigree cats, based in the US. It keeps pedigree records, writes breed standards and runs cat shows. All terms calls it one of the great treasures of the cat fancy, because so many other breeds were inspired by it or descend from it [1]. Siamese are famously chatty and deeply people-focused [1]. In 2025 it was the fourth most-registered breed at the UK's GCCF (Governing Council of the Cat Fancy): The UK's oldest pedigree cat registry (since 1910). All terms [3].

History
Pointed cats appear in Thailand's Tamra Maew (Cat Poems), written during the Ayutthaya period (1350–1767) [1][6]. In the late 19th century, British visitors brought these blue-eyed cats home as "Siamese", and they soon appeared at the Crystal Palace cat shows in London [1]. The first Siamese on record in the United States was "Siam", sent to President Rutherford B. Hayes by the American consul in Bangkok in 1878 [1]. The Siamese was one of the first breeds CFA recognised when it was founded in 1906 [1].
Seal point was originally the only colour. CFA later accepted blue point (1934), chocolate point (1952) and lilac point (1955) [1].
Genetically, a 2008 study found that Southeast Asian breeds, including the Siamese, cluster with random-bred cats from Vietnam and neighbouring countries [2]. That makes the Siamese a distant cousin of Vietnam's own mèo ta.
Appearance
- Body: medium-sized, long and tubular, fine-boned but firmly muscled. Long legs (the hind legs higher than the front) and a long, tapering tail [1].
- Head: a long wedge with a straight profile from the top of the head to the tip of the nose. The ears are strikingly large, pointed and wide at the base [1].
- Eyes: almond-shaped and deep vivid blue [1].
- Coat: short, fine and glossy, lying close to the body [1].
- The points: a mutation in the TYR gene makes the pigment enzyme heat-sensitive, so colour develops only on the cooler extremities [8][9]. CFA's standard notes that Siamese generally darken with age [1].
CFA says that during the 1950s boom, rounder-headed, heavier-boned cats were bred to meet demand, while the show standard never changed [1]. Cats of that older, moderate type are now recognised by TICA (The International Cat Association): An international cat registry based in the US and one of the largest. It often recognizes newer breeds before CFA does. All terms as a separate breed, the Thai [6].

Temperament
CFA describes the Siamese as unmatched in its ability to communicate with people, through body language and a huge vocal repertoire [1]. They head for the warmest spot in the house, which is usually your lap. They want to be involved in whatever you're doing and will complain loudly if you shut them out [1]. Another person or another Siamese makes the ideal companion, though many get on well with other pets [1].
Care
Health
- Progressive retinal atrophy (PRA (Progressive retinal atrophy): An inherited eye disease that slowly worsens sight and can lead to blindness. All terms ) can cause blindness. It's Recessive gene: The trait only shows when a cat gets the gene from both parents; carriers look normal. All terms , and a genetic test lets breeders avoid producing affected kittens [1].
- Amyloidosis causes liver problems. Its genetics are still being researched, so ask breeders about any family history [1].
- Lifespan: an English study recorded a Median: The middle value: half the cats lived shorter than this, half lived longer. All terms age at death of 14.2 years (31 cats) [4]. VetCompass: A Royal Veterinary College research programme that studies anonymised records from hundreds of UK vet clinics. All terms life tables put life expectancy at birth at about 11.7 years [5]. VCA estimates 12–15 years [10].
For any specific health concern, talk to your veterinarian.
Don't confuse with…
- Thai (Wichienmaat, "Old-Style Siamese"): moderate type with a rounder head, a separate breed in TICA [6].
- Oriental Shorthair: the same body type, but without the pointed pattern, in a huge range of colours and usually with green eyes [7].

Cat facts
- A Siamese coat is basically a heat map: the cooler the body part, the darker the fur [8][9].
- The same Colorpoint: A pale body with darker face, ears, legs and tail, like a Siamese. All terms mutation turns up in pointed Persians, the Himalayan [8].
- America's first recorded Siamese was a diplomatic gift to President Hayes in 1878 [1].
Frequently asked questions
Are Siamese cats very vocal?
Yes. Siamese are famous for "talking" to their people through body language and a big repertoire of sounds, and they'll protest loudly when left alone [1].
Are Siamese cats easy to keep?
The coat is easy, since a damp hand or a rubber brush will do [1]. But Siamese crave attention and want to be part of everything you do, so they suit homes where someone is around a lot or where they have a companion [1].
Why do Siamese cats have dark faces, ears and paws?
A TYR gene mutation makes the pigment enzyme work poorly at warmer temperatures, so only the cooler extremities darken [8][9]. CFA (Cat Fanciers' Association): The world's largest registry of pedigree cats, based in the US. It keeps pedigree records, writes breed standards and runs cat shows. All terms 's standard notes that Siamese generally darken with age [1].
How long do Siamese cats live?
An English study recorded a Median: The middle value: half the cats lived shorter than this, half lived longer. All terms age at death of 14.2 years (31 cats) [4]. VetCompass: A Royal Veterinary College research programme that studies anonymised records from hundreds of UK vet clinics. All terms life tables give a life expectancy at birth of about 11.7 years [5]. The two methods measure different things, which is why the figures differ.
What's the difference between a Siamese and a Thai cat?
The Thai (Wichienmaat) keeps the moderate, rounder-headed look of early-20th-century Siamese. The modern show Siamese has a long wedge-shaped head and a longer, more slender body. TICA (The International Cat Association): An international cat registry based in the US and one of the largest. It often recognizes newer breeds before CFA does. All terms recognises the Thai as a separate breed [1][6].
