Here's Why ALL Siamese Cats Have Blue EyesSiamese cats are a special breed that many people love because of their unique fur patterns and striking blue eyes. They were once royalty in the ancient kingdom of Siam which is now Thailand. While the Siamese may hide genes in other cats, there must be genes in both parents to produce the large pattern and telltale blue eyes.

This is why all Siamese cats have blue eyes! Siamese cats have specific traits that breeders have genetically had for hundreds of years. Blue eyes are the result of recessive genes. Both parents must have the gene for the cat to exhibit blue eyes.

All cats have captivating eyes in a variety of colors. Most people think of glowing eyes that glow in the dark when they think of cats. There are no surprises with properly bred Siamese cats. Most breeders ensure that their cats do not mate outside of the proper gene pool.

Here’s Why ALL Siamese Cats Have Blue Eyes

Siamese cats have a type of albinism. This can be a bit difficult to understand, as they obviously don’t look like traditional albino animals. The genes responsible for blue eye color, however, represent temperature-sensitive albinism.

This temperature-sensitive albino appearance also explains why their coats are different colors at the ends. The gene is heat sensitive, so the color of their body core is different from that of their legs and tail.

Siamese cats are all white at birth because the albinism trait is active in the warm temperature of the womb. They stay warm while nursing and also snuggle up to the mother. Eventually they pull away from mom and the colors start to change.

The structure of the eye

The basic structure of the eye involves the iris and the pupil. The iris has two layers. The cells in these layers affect the color of the eyes.
Pigmented cells are present in most cats. Siamese cats and a few related breeds, however, lack this pigment. It’s because of the temperature-sensitive albinism gene.

A Siamese cat’s blue eyes appear because both layers of the iris lack pigment. Blue eyes may still be present in cats that have pigment in one coat, but a true Siamese cat’s eye has no pigment. If you observe closely, you will notice that the shade of blue changes in different environments.

Wave length

All colors in the spectrum are available in the iris, but humans see blue because the wavelength is shorter than other colors. If you are familiar with the beginnings of science, you may also know that the wavelength of violet is also short. However, humans have a hard time recognizing it, so our eyes focus more on blue.

Siamese cat eyes are blue because humans see them that way. It’s interesting to think about how other creatures might see them.

Selective breeding of Siamese cats

Siamese cats didn’t always look the way they do today. The royal families of Siam (now Thailand) began to domesticate them in the 14th century. Significant changes came with selective breeding when Siamese cats arrived in Europe in the late 18th or early 19th century.
Modern Siamese cats have a pointed coat pattern, a triangle-shaped head, and a slender body.

The original version of the Siamese cat was much rounder all over. The old version is still available today. Experts call it a traditional Siamese cat or a Thai cat. Selective breeding for a slimmer Siamese cat began due to the preferred shape for cat shows. The first Siamese cats also had crossed eyes and curved tails. The blue color of the eyes, however, persisted.

Crossed eyes and curled tails

The albino gene that causes blue eyes prevents the eyes and brain from communicating properly. This neurological problem leads to severely crossed eyes. Breeders have mostly eradicated crossed eyes in modern Siamese cats.

The other problems that accompany the persistence of the albino gene. Night vision has not improved, as the necessary extra layer in the eye is still missing. Breeders want blue eyes to remain the main feature; therefore, this is unlikely to change.

Breeders also consider bent tails a defect. Over the years, the iconic curved tail of the historic Siamese cat has disappeared. However, there is no shortage of curled tails in Thailand’s standard cat population.

Siamese cats and view

Cats are known for their sharp eyesight and night vision. Cat owners often encounter a pair of glowing eyes in the dark. However, Siamese cats may be less likely to walk around at night. They have difficulty seeing in the dark, which can lead to injury.

Siamese cats still have the hallmark night vision, but there are limitations. Ordinary cats can see small features, while a Siamese cat can only see a basic shape. This is another effect of the temperature sensitive gene they carry.

Ordinary cats also have another layer over their eyes called the tapetum lucidum. This layer provides the perfect configuration for large amounts of light to pass through the retina. Siamese cats therefore receive less light in their retinas. This can cause imperfect day and night vision, but it severely limits night vision.

stubborn nature

Siamese cats are known to be demanding. They let their owners know when they want attention or don’t like something. They can go to great lengths to achieve their ends. This attitude, like the blue eye gene, can inhibit necessary natural instincts.

Food is a common problem with Siamese cats. They decide if they don’t like their food or just refrain from eating to get something better. It is essential to get as many nutrients as possible at each meal.

With the lack of night vision and the will to stop eating, you might be wondering how a Siamese cat could survive in the wild. Like all pets, Siamese cats have many learned behaviors that would not suit them in the wild. When you combine this with unique breeding practices, you get cats that need humane care in a safe environment.

Health problems

Many animals with albinism genes have health problems. Siamese cats have a shorter lifespan than most cats. You can expect your Siamese cat to live for around 10 to 12 years. Many other breeds live over 20 years.

Siamese cats are prey to mammary tumors, feline OCD and feline hyperesthesia syndrome. They are, however, more resistant to urinary tract problems. You should also monitor kittens closely for lung problems.

While lack of pigmentation can cause deafness in white pets, Siamese cats are not prone to hearing loss. The gene does not cause a complete lack of pigment and simply depends on body temperature.

Cultural history

In their native kingdom of Siam, Siamese cats lived in royal homes and the Burmese stole them. After the Siamese and Burmese War, Burmese people associated these cats with wealth after reading a poem about them. They thought they would get rich if they owned a Siamese cat.

It is unclear if this is a legitimate reason for a low Siamese cat population in Thailand today. Some say it’s just a war story, fictional in nature. Breeding efforts are taking place today in Thailand to preserve this historic pet.
Some stories also say that cats are only associated with royalty, as only wealthy people could afford to take care of pets. Either way, Siamese cats lived in luxury.

Myths about Siamese cats

There were also stories of Siamese cats taking the souls of deceased royalty. This allowed the left to stay in a temple with servants and lead a luxurious life.

The crossed eyes and curved tail are part of a myth about a Siamese cat guarding a special vase. The legend says that the cats became sleazy as they stared intently at the coveted vase. The story also says that the tails of the Siamese cats permanently bent because they kept them wrapped around the vase.

Another myth states that the curvature of the tail resulted from holding the princess rings on the tail. The tail had to bend so the rings wouldn’t slip.

fly high

Poor night vision doesn’t stop Siamese cats from jumping around. They are very agile and energetic. During the day, they can still see the details well. This allows them to jump to the highest places in your house.

Don’t be surprised if you see your Siamese cat on a top shelf or on top of the refrigerator. Their slender and long bodies allow them to reach great heights with grace.

Amuse your Siamese cat by providing large scratching posts to climb on. However, don’t expect them to stick to their own objects for climbing. Cat-proof your home, so your Siamese cat stays safe and turns on the lights if he wants to prowl at night.

The cost of this beautiful blue

Serious breeders are aware of the traits they encourage. Customers pay a premium price for a show-quality Siamese cat. You can expect to pay between $400 and $1,000 for a Siamese cat. Some may not even come with papers.

These cats do not live as long and require a lot of attention. You must make a formal commitment when bringing a Siamese cat into your home. You pay a significant price for a particular look. This look comes with added responsibilities.

Siamese cats should not roam outdoors alone due to their limited vision. In the dark, they can easily run into traffic or get hurt from a conflict with another animal. The desire for human attention is also a breed trait, and a Siamese cat lets you know when it wants attention.

Final Thoughts

A Siamese cat’s blue eyes are the result of the gene allele that affects its entire body. Their albino determines their fur and eye color genes. The eyes of Siamese cats in the past were squinty due to the neurological effects of lack of pigmentation. The structure of the eye, however, also poses a problem.

A layer of the eye is missing, controlling the amount of light that reaches the retina. Don’t expect your Siamese cat to be a great hunter in the middle of the night. Modern Siamese cats are different from the ancients in many ways. The striking blue eyes, however, have not changed.
