Why does a cat s eyes have two colors

The color of cat eyes varies significantly from breed to individual, the color of the eye is determined by the color of the retinal pigment layer, the deposition of the color of the retinal pigment layer is determined by genetics, different breeds have different genes, so the color of the eyes is different, although the color of the cat's eyes is not as ever-changing and colorful as the coat color, but there are also a variety of colors, the common ones are yellow (from light yellow to dark yellow), blue, bluff color, copper, green, light brown, etc., It is generally believed that there is a correlation between the color of the eyes and the color of the coat. For example, the color of the eyes of a Persian cat is often related to the color of its coat, and when the color of the eyes of a Persian cat is the color of a mandarin duck (one blue, one yellow), its coat is generally white; When the eye color is green, bluff color and gold, the coat color generally belongs to the silver-gray coat color series; When the eye color is copper, the coat is considered to be a different coat color, including white.

When observing and evaluating the eye color of cats, in addition to paying attention to the various colors of eye color, it should also be noted that any color should be darker and purer, and the more uniform the color of the eyes, the better.

Mainly the relationship between parents and genetics, Kenneng parents' eye colors are different, or more distant such as grandparents' eye colors, mainly because there are many kinds of cats' eye colors, dogs only need one, except for huskies have two colors of eyes, blue and black, so huskies also have mandarin duck eyes.

The color of a cat's eyes is determined by the genes in its body.

The parent's eye color is more stable, and its eye color will be more beautiful.

Netizens who have cats will find that the color of the two eyes of existing cats is different, and this phenomenon is called mandarin duck eyes, and the scientific name is called heterochromia. This symptom often appears in white cats, because ordinary white cats are actually accompanied by genetic defects, for example, the blue-eyed kittens in the home will indeed be very beautiful, but the ears of this kind of kittens may be deaf, in this case the kitten has some defects. In order to make the kitten healthier, this kind of crossbreeding will be introduced to breed the mandarin duck-eyed cat.

People use yellow-eyed white cats to cross this blue-eyed white cat to give birth to a mandarin duck-eyed cat, which means that the kitten born has one eye blue and one eye is yellow. Such kittens may be healthy, but there are also some crossbred kittens that have blue eyes and are deaf on one side of the ear. Therefore, if you find that the eyes of the kitten in your house are mandarin duck eyes, you need to take the kitten to the hospital immediately for examination and examination to see if the kitten's body has some defects.

The lion cat is the most common mandarin duck with the eyes, this kitten has a very gentle personality and looks particularly like a Persian cat. The reproductive ability of this kind of kitten is relatively low, so the number of purebred kittens in China is very small, and most of them are crossbred. Different breeds of cats have different eye colors, most kittens have yellow eyes, in addition to amber, blue, green, light brown and purple steel are common in cats, in addition to the cat's eye color is also different.

The reason why kittens' eyes appear in different colors is because of their different qualities. The color you see is actually the color of the kitten's retina under the eye, and the kitten's ability to store and absorb color is different, so the final color is also different. Don't judge the health of a kitten by the color of its eyes, but take the kitten to the hospital for examination to determine whether the kitten is healthy.

The reason why some cats have different eye colors is because of genetic mutations or genetic defects, and it may also be because of the breed of cat.

Such cats are generally sick, and his abnormal eye may not be visible. Cats' eyes suffer from a disease that is unique to cats, which is why their eyes change color.

Because their genes are different. The appearance of two eyes of different colors indicates a genetic mutation. But this is very rare.

Blue-eyed white cat, ancestors are Angora cats, Persian cats. Originated in the 1880s. The habit is docile, and the ears are at the head position.

The limbs are lower and the neck is stubby, and the coat is delicate and silky"Blue-eyed white cat"It is a general term that refers to cats with blue eyes and white coats, which can be native cats or breed cats.

One blue-eyed and yellow-eyed cat is called a heteropupil cat.

Heterochromic pupils, also known as mandarin duck eyes. Refers to the condition that two eyes of the same animal are of different colors, usually in white cats. Generally speaking, purebred cats have the same eye color, and the mandarin duck eyes are the result of crossbreeding.

This is a Persian cat, and the characteristic of the Persian cat is that it has two eyes, one yellow and the other blue.

Third, the color of the cat's two eyes is different, and it is necessary to divide the specific situation, if it is a kitten, the two colors are different, it may be because of genetic problems, not lesions. Purebred cats have the same eye color, and mandarin duck eyes are generally thought to be caused by hybrids. If it is not the case that the cat has grown up and has only appeared recently, then it may be that there is a lesion in both eyes, see if there is a problem with nutrition, or there is a lesion in the internal organs, and go to the hospital for a checkup.

Find out the cause early.

The change of the cat's eye color should also attract our attention, and we should pay attention to the cat's health problems and reduce the occurrence of lesions.

This situation shows that the cat is a hybrid breed, although the cat with simple blue eyes was cute but had deafness, and later people crossed with yellow-eyed cats, and the offspring with mandarin duck eyes were not deaf, this situation is also called "heterochromia", not a lesion.

Cats have different eye colors, which may be due to genetic factors, genetic mutations, and of course, some diseases, such as cataracts.

It is not a lesion, Persian cats have bichromatic pupils, and cats with bichromatic pupils are generally predominantly white.

Because the pupils of cat's eyes change periodically throughout the day and night with the intensity of external light. The details are as follows:

At noon during the day, the light is strong and the pupils are narrowed, showing a vertical line up and down; At night, when the light is weak, the pupils are fully dilated and circular, and at other times they are oval in varying degrees.

Because the pupils of cats are large, the muscles responsible for pupil contraction are well developed, and the contraction is particularly strong. The cat's function of changing three times a day is completed with the help of the strong expansion and contraction ability of the pupil.

It can adjust the intensity of the light entering the eyes, so that it is always at a level sufficient to excite the Shen Sui Lu meridian, so that the cat can clearly see various objects in the outside world regardless of day or night, which is of great significance for the cat's nocturnal activities and foraging, so sometimes there is a slight difference.

The color of the cat's two eyes is not the same is caused by genetic factors, generally called heteropupil, which is a normal situation, if the cat's eyes look blurry, similar to clouds, then it may be due to cataracts and other diseases. The two cats are not the same color, which is generally called heteropupil. This is due to the cat's genetics, which generally have no effect on the cat's vision, so the owner does not need to worry too much.

However, if the cat's hair is white and there is a manifestation of abnormal pupils, it may cause the cat's hearing impairment, which is caused by congenital genetic defects, and there is no way to do it in any way.

The different eye colors of cats are caused by genetic factors, which is a normal condition and generally does not affect the health of cats. If your cat's eyes look blurry and cloud-like, it may be due to a disease such as cataracts. In addition, if the cat's eyes are glowing green or cyan, then consider glaucoma due to increased intraocular pressure, and it is recommended to take it to a pet hospital in time.
