Siamese

About the breed

The Siamese is the archetype of the 'talkative' cat: an ancient breed from Thailand built around striking blue eyes, a short colourpoint coat, and a personality so social it is often compared to a dog. Because the breed has been shaped by roughly a century of competitive showing, today's pedigree Siamese looks quite different from the cats first described in old Thai manuscripts, and a handful of the breed's most talked-about quirks - crossed eyes, kinked tails, a predisposition to a specific liver disease - trace back to real, documented genetics rather than folklore.

Origins in old Siam

Pointed cats matching the Siamese description appear in the Tamra Maew, manuscripts of cat poems from the Ayutthaya kingdom (1350-1767), making the type one of the best-documented old cat lineages anywhere. Western accounts describe them living in and around the royal court in Bangkok before the first cats reached Britain and the United States in the late 1800s - a pair was reportedly presented to US President Rutherford B. Hayes in 1878. The Cat Fanciers' Association recognized the Siamese in 1906, among its founding breeds, initially in a single colour (seal point), with blue, chocolate and lilac points added over the following decades.

Traditional vs. modern type

From the 1950s onward, competitive breeding pushed the show-ring Siamese toward an increasingly extreme silhouette: a long, tubular body, a narrow wedge-shaped head, and very large ears, as favoured by CFA and TICA standards today. The rounder-headed, more solidly built cats that resemble the original Thai population are now bred separately, often under the name 'Thai' (recognized by TICA and WCF) or described informally as 'traditional' or 'applehead' Siamese. Neither type is more 'correct' in an absolute sense, but the two differ enough in build that health and temperament expectations can vary between them, and buyers should be clear on which type a breeder is offering.

Vocal and highly social

Surveys of feline personality across breeds have found real, heritable differences in sociability and demand for contact, and the Siamese sits at one extreme: it is consistently described as the most vocal common breed, with a wide range of calls from soft chirps to loud, low-pitched demands that many owners compare to a crying baby. This isn't a marketing exaggeration - it reflects genuine selection for a highly people-oriented temperament, and Siamese generally do not cope well with being routinely left alone for long hours, often forming an intense bond with one household member.

Crossed eyes, kinked tails

Both traits were common, and sometimes even valued, in early Siamese lines, and they are not unrelated folklore: the same mutation that produces the breed's pale body and darker 'points' is a temperature-sensitive form of partial albinism, and research on Siamese cats (particularly the work of neuroscientist Ray Guillery from the 1960s onward) showed that this mutation also disrupts how the optic nerves route themselves during development, causing many Siamese to be born with a form of crossed eyes (strabismus) as the brain compensates. Kinked tails were a separate, likely skeletal, trait that travelled with the same old bloodlines. Decades of selective breeding against both faults have made them far less common in pedigree show cats, though they can still occasionally appear.

Health risks to know

Siamese and closely related Oriental-type cats carry a documented, elevated risk of hereditary (AA) amyloidosis, a familial disease in which abnormal proteins accumulate in the liver and thyroid; onset is typically between 1 and 5 years of age, and severely affected cats can die suddenly from liver rupture. One UK-focused study found the condition in over 6% of Siamese cats studied, compared with roughly 1% across cats generally, though no genetic test yet exists to identify carriers before symptoms appear. Separately, a mutation in the CEP290 gene causes a recessive, late-onset form of progressive retinal atrophy; it is carried at a notably high frequency in Siamese lines (roughly one in three cats tested in older surveys), and a DNA test is available so breeders can screen for it.

Everyday care needs

The short, fine coat needs only occasional brushing and sheds relatively little, which makes grooming one of the easiest parts of Siamese ownership. What takes more effort is everyone's favourite part of the personality: this is a high-energy, intelligent breed that gets bored quickly without climbing space, puzzle feeders, or regular interactive play, and an under-stimulated Siamese can become destructive or excessively vocal. Because the body is naturally lean, owners are also advised to watch portion sizes carefully, since weight gain shows quickly on the breed's slender frame.

Is it right for you

Siamese generally do well with children and with other sociable pets once introductions are handled patiently, and their adaptable, people-focused nature means many thrive in apartments provided they get enough attention and vertical space. What makes them a less obvious 'beginner' breed isn't the coat or the size - it's the sheer amount of company and mental stimulation they expect; a Siamese left alone for long working days, in a quiet household, is likely to be a frustrated, and very loud, cat.
