Contrary to our human eyes, which only have a color in the middle of the pupil, cats have colors in the iris around the pupil; the iris can adjust the size of the pupil, and the amount of melanin can determine the color of the iris.
Different breeds of cats have different eye colors, common yellow (from light yellow to dark yellow), blue, amber, copper, green, light brown and so on. This is mainly determined by the color of the retinal pigment layer. There is also a situation where the color of the iris on both sides is different, which usually occurs in white cats, called "iris heterochromia".

In fact, the color of the cat's eyes that we see is the color on the cat's fundus retina seen through the transparent cornea. The deposition of pigments in the retina and in the hair follicles of the skin has a certain correlation. Therefore, there is a certain connection between the color of the cat's eyes and the color of the cat's back hair. For example, flower cats do not have blue eyes, black cats have mostly green eyes, and long-haired white cats are mostly blue.
The eye color of the cat is also one of the important bases for identifying purebred cats. The eye color of some purebred cats is fixed to a certain color, such as purebred Siamese cats, purebred Himalayan cats, the eyes must be blue. If a cat looks the same as a purebred cat, but the eye color does not match the eye color of the purebred cat, it means that the cat is not purebred and has been mixed with other breeds of blood.
Two Mandarin duck-eyed cats
Baidu Encyclopedia: Mandarin duck eyes, also known as "strange eyes", refer to the situation that the two eyes of the same animal have different colors, usually appearing on white cats. It is generally believed that the two eyes of purebred cats are the same color, and the Mandarin duck eyes are caused by hybridization. Some cats (such as the Chinese Linqing lion cat and the Angolan cat) are mostly genetically defective, with very beautiful blue eyes and deaf ears. Therefore, people use yellow-eyed white cats to cross with this cat, breeding Mandarin duck-eyed cats, a yellow and blue-eyed white long-haired cat, but the blue-eyed side may also have deafness defects. Persian cat eye color depends on the coat color, it is generally believed that the color of persian cat eyes is blue, green, copper, gold, amber, strange color and two eyes have different colors (i.e. Mandarin duck eyes). The coat color of the Mandarin Duck-eyed Persian cat is often white. Cats with green, amber and golden eyes generally belong to the silver-gray coat color. The purer and darker the color of the various eyes, the better, and it is better to have a uniform color of both eyes. Lion cat It is a typical Mandarin duck eye, with blue and yellow eyes, usually the fur is white, the personality is gentle, the shape resembles a Persian cat, and it resembles the form of a lion, so it is called a lion cat. Due to its low reproductive ability and few purebreds, it belongs to one of the famous cats in China. Cats have a very sensitive sense of hearing, and their positioning function for sound and the balance function of the inner ear to regulate the body are stronger than those of humans. However, cats, like other animals, have congenital and acquired deafness. Some people say that blue-eyed cats can't hear sounds, but this is actually a misunderstanding. For example, Siamese cats are mostly blue-eyed, but the proportion of deafness is very small. However, statistics show that the proportion of white-haired blue-eyed cats with deafness is higher, which is likely to be related to genetic factors. Congenital deafness syndrome occurs mainly due to genetic abnormalities on the autosomal body, which leads to the development of deafness due to hypoplasia or inexplasia of organs such as the Cotigi and the cochlear helix ganglion.
The iris of kittens is almost a little cloudy, dark or light blue because the pigment has not yet been fixed; until about three weeks old, their eye color will slowly change, and the blue will gradually fade and transform into other colors; and with the change of iris color, the eyesight of the kitten will also begin to become stronger, and they can see the surrounding environment, light, and the color of objects.
Even cat owners do not necessarily have the blue-eyed period of seeing their own cats; because this is the characteristic of newborn kittens, if it is not a cat with a small milk, ordinary people will not have the opportunity to see it. And this can also be used as a basis for judging the age of the cat, that is, if a small meow is picked up on the road, if it is found that its eyes are still cloudy blue, it means that it is a small milk cat born within three weeks.
