Heterochromia in Cats: Different Colors of Cat’s Eyes

The difference in the color of the iris is called heterochromia. Such an anomaly in humans is quite rare. More often you can see different-eyed cats or dogs. In most cases, heterochromia is not a consequence of the disease or pathology, but is associated with a failure in the mechanism of pigment production. Sometimes it is inherited, a characteristic characteristic of several breeds of cats.

Features of heterochromia

Cat fans have different attitudes to this phenomenon. Some people deliberately look for such a pet, consider it a symbol of good luck and well-being. They are rightfully proud of their unique cat, care for and cherish it, and provide ideal conditions for the pet to remain a reliable mascot for as long as possible.

This attitude to different-eyed animals has a reason. Many peoples have a belief that the presence of such a cat in the house guarantees him protection, helps the owner to achieve any goal. The followers of Islam know that the prophet Muhammad was very fond of his ward, with Muizzu.

There is also modern evidence in favor of cats with heterochromia. As soon as bill Clinton got such an animal in the house, he soon managed to win the election and become President. There are also people among cat lovers who consider different-eyed Pets representatives of evil spirits. During the Inquisition, women with heterochromia were called witches and burned at the stake. Many Eastern fortune-tellers, fortune-tellers get a cat with different eyes to enlist the help of otherworldly forces.

And yet there is no reason to consider a pet with different eyes a bad sign. It is better to get acquainted with the scientific explanations of heterochromia, to treat this phenomenon adequately.

Types of heterochromia

Experts distinguish several types of these anomalies. As a criterion by which they are classified, the distribution of shades on the iris is taken. Heterochromia can be:

  • complete,
  • ring road,
  • sectoral.

In its full form, the anomaly appears as a uniformly colored iris. In most cases, one eye has a rich blue color, the other can be yellow, orange, green, copper, etc.

When the ring heterochromia of both iris are the same color. But on one of them there is a zone in the form of a ring, painted in a different color. A sectoral anomaly characterizes the presence of an area with a color that does not coincide with the General shade. This phenomenon can be observed in one eye or both.

In most cases, a kitten is born with impaired iris pigmentation. Sometimes the anomaly is acquired, and a change in the color of one eye is caused by certain external causes. There are cat breeds in which heterochromia is a genetic trait.

Causes of the anomaly

A congenital anomaly is not a disease, the body of a multi-eyed cat functions in the same way as in ordinary Pets. There are no changes in visual acuity. The only disorder that can occur in some cases in animals with different eye colors is poor hearing or complete deafness. Therefore, breeders of purebred cats reject such kittens, do not use them in breeding.

Heterochromia can be observed in animals of any color. But most often, the abundance or lack of pigments occur in Pets with white, light hair, tricolor cats. Usually pronounced differences in eye color appear by the age of three months.

Acquired heterochromia is a consequence of the use of certain medications or indicates the presence of a disease. For example, in the treatment of glaucoma, eye drops are used, the components of which activate the production of melanin. As a result, the iris gets a darker shade. Lightening is often a sign of diseases:

  • leukemia,
  • melanoma,
  • aevita,
  • diabetes,
  • neuroblastomas, etc.

Acquired heterochromia should be the reason for a visit to the veterinarian, diagnostics.

Different eye color as a sign of the breed

Not always different eye color is an anomaly. There are breeds of cats in which this trait is inherited, it is considered one of the characteristic features. These include:

  • Turkish Angora,
  • kao Mani,
  • the Turkish van.

Representatives of these breeds have a snow-white color or white is the main color in them.

Various disasters and wars have put the Turkish Angora breed in danger of complete extinction. The Turkish government’s attention to these animals helped prevent the disaster. Now cats of this breed are protected by the state and are a national treasure.

The most expensive and rare pet is the kao Mani cat. Since time immemorial, these animals live in Thailand. Short-haired snow-white cats, like representatives of the Turkish Angora, are protected by the state and are considered the national breed of Thailand.

The Turkish van breed is the result of breeding. The progenitors of modern representatives were wild cats that live on the shores of lake van. The main prey of these predators is fish. Each hair of thick semi-long wool is qualitatively smeared with subcutaneous fat. The cat does not get wet during water hunting.

It was Turkish vanes that provided popularity for different-eyed Pets. In the Turkish city of van, a monument was erected to the multi-eyed cat. One eye represents the sun, has a Golden hue, the second symbolizes the sky, its color is blue.

Heterochromia in animals of these breeds is manifested similarly. One eye has a deep blue hue. The color of the other iris can be amber, honey, green, or orange.

Heterochromia in other breeds

In view of the anomalies of different eye color can also appear in animals of different species. This phenomenon is often observed in cats:

  • marble and tortoiseshell color,
  • Persian,
  • exotics,
  • sphinxes,
  • Oriental,
  • British,
  • Scottish,
  • Rex.

You can see multi-eyed cats among yard tricolor individuals. In most cases, different shades of the iris are formed in animals whose color white occupies more than half of the body area.

The manifestation of this feature is unpredictable, can be observed in cats of any breed. There is only one condition for the formation of a different color of the iris. The animal must have a white gene passed down by inheritance.

Heterochromia in white cats

In albino cats, the formation of heterochromia occurs according to a special scheme. These animals have a dangerous dominant W gene. It has several types. If kittens get the gene in a homozygous form, they die in the womb.

The presence of element W in domestic white cats can negatively affect the formation and development of the nervous system. This gene can cause serious disorders of the functions of the organs of vision, hearing, leading to blindness, deafness.

If heterochromia is not a sign of the breed, and there are deviations in the behavior of the animal, then you should show the pet to a veterinarian and undergo an examination. It is necessary to visit a veterinary clinic and with an acquired anomaly, to exclude the presence of minor diseases that could contribute to the appearance of eye color in the animal.
