Actually, it is not the final pigment that creates the blue -eyed kitten look. Kittens are just like any baby mammal, it takes time for them to mature.

Cats eye colors can range from yellow, green, brown, or blue and many shades in between. In fact, eye color is so genetically defined that some breeds of cat have specific colors allowed by the breed registry.

The lack of pigment that appears blue is defined by their DNA as well. In fact, up to 85% of white cats with blue eyes will also suffer from congenital deafness 1.

Studies have suggested that some cats with permanently blue eyes (in this case, Siamese) have changes in their brains because of the difference that the lack of pigment makes in the way the eye handles light.² Who your cat is, the way he hears, sees, and even looks are expressions of his genetic map. Adult eye color is genetically defined, but baby kitten blue eyes are not the same.

If you love your kitten’s baby blues, don’t despair. If he is meant to be a Frank Sinatra among cats, like the Siamese (in eyes and voice), it is already written on his genes and all you have to do is wait and see.

Keep in mind that the majority of the world’s population, including many people in the US, doesn’t have a clue as to what differentiates between different eye colors and actually assume that all kittens are the same. They can be a result of an allergy from something like dust, fleas, or any other part of the cat’s body.

This is one way that a cat can appear differently colored to many people, even though it is not a true physical defect of the eye. Another reason why most people assume that all kittens are born with blue eyes is because they are usually much lighter than all the other colors in the cat’s coat.

Many people do not realize this, but kitties should have the same dark coat all over, but their eyes may be different. Another thing that makes these eye colors unique is the amount of melanin that is in them.

While most human beings have a fair amount of melanin in their eyes, most cats have much more. The answer is Yes, most cats do have blue eyes all the time, although they can have a little of melanin and give you a totally different look.

However, kittens are just like humans in that some of them will not have a mixture of all the colors and this means that you can be aware of them, and sometimes, catch them out, but that is all they will do. But, as cute as kittens are, they can also be very rough on their eyes, and in a few months, they can look like a different animal altogether.

Even if you buy your kitten from a breeder, don’t expect that he will live forever with you. There is nothing worse than having a baby sits on your lap for years and having to give it up.

It is easy to purchase training tools for cats, but many times, it is harder to get your kitty to follow those instructions. For example, if you are training your kitten to sit on your lap, the best thing that you can do is to play some games with them, so that they will know that they are not doing something wrong.

But, you have to remember that every little thing that you do for your kitty will help in the long run. As long as you keep their eyes healthy, they will be happy forever.

The answer is simple: a diet high in naturally occurring melanin. And when a mammal has very little of this pigment, the animal will not be able to absorb enough ultraviolet light to protect itself from exposure to the sun.

In cats, eye color is hereditary, although it can sometimes occur in a variety of different ways. It has been shown that certain types of leukemia and lymphoma do not respond well to the dosage of chemotherapy that is often used to combat eye color.

In such cases, veterinarians recommend using a drug called brachytherapy to keep the eyes from drying out. There is some debate about whether this is a safe method of treating eye color, however.

So how do you determine which kitten’s eyes will be different colors and which ones won’t? As with any baby there is always a chance that they will have some vision issues during their early years.

When kittens are around a month old, their eyes will start changing color from blue to amber, gold, iridescent green, or even yellow-gold. The fact is that hereditary deafness does tend to be a serious concern in white cats.

A pure white cat with blue eyes has an 85 percent chance of some degree of deafness. Cats that have those beautiful blue eyes have lower levels of melanin in their eyes.

Although they may be at a greater risk for congenital deafness, there’s no history of more cases of blindness than any other cats. And, every single shade of Airman, as well as other breeds, looks spectacular in contrast to their striking blue eyes.

It’s because these cats simply have the ability to plop themselves down in complete comfort, drape themselves on the couch, or loll around in the warm sun. Hopefully, all this talk about deafness and genes hasn’t scared you off from wanting to adopt a blue -eyed kitty.


Blue Eyed Cats : Cats can have eyes of very varied colors and of varying intensity emerald green, copper orange, yellow amber etc. In most cases this feature is due to perfectly determined genetic patterns so if you want to make sure your cat has blue eyes you must know them.

Cats with light hair on the body and with legs, face and tail of a darker color are called cats with “pointed color scheme”. Siamese cats always have this color scheme and are the only breed that will always have blue eyes.

When the white spot gene affects both eyes the cat will have blue eyes. A study from Vanderbilt University found that Siamese cats generally have a less clear vision than other cats this corresponds to low levels of pigmentation in the color of their eyes.


For this reason the Siamese cats tend to be less active at night. The white color is very striking in full light giving these felines a resplendent appearance.

However, as in the rest of its members in albino cats there are circumstances that do not seem to be related as in the case of deafness. Therefore, we invite you to continue reading so you can discover the reasons for this strange condition.

White color of the coat occurs in cats in the following three ways: Hope you have got some information about the blue-eyed cats and why they are deaf.

Also, we will highlight and explain some common myths people have about cats with blue eyes. There is a common belief that all blue -eyed cats are deaf and dumb.

In some ancient superstition, white-coated cats were believed to be a sign of bad or good luck. Neural cells known as melanocytes are responsible for the formation of eye color.

Melanocytes produce melanin which affects eye and skin pigmentation. Within 6 to 7 weeks of the kitten being born, it will have enough melanocytes to change the blue eyes to its true color.

A cat breed is known as Rag dolls also get blue eyes which appear exceptionally sparkly. The Turkish Angora and Snowshoe cats also sire kittens with blue eyes.

Ojos azulesSince melanocytes are found below the skin, they will also affect a cat’s coat color. What most people don’t know is that such a cat suffers from albinism because of few melanocytes in its skin.

This is a rare phenomenon seen in the Dojos Azures cat breed. But some cats with blue eyes suffer from partial or total deafness.

Melanocytes produce melanin and also aid in the development of auditory cells in the ears. Since blue -eyed cats have few melanocytes, their hearing ability may also be affected.

Only blue -eyed cats with a dominant white gene are likely to be partially or totally deaf. This is because they have very few melanocytes which prevent them from expressing their true eye and coat color.

For other blue -eyed breeds, hearing loss will only be partial or total in one ear. This red color should be confused as pink eyes which are a sign of an underlying disease.

Blue -eyed cats with a dominant white gene also suffer from skin issues because of their albinism. Only cats with low numbers of melanocytes are likely to suffer from deafness.

Cat breeds with blue eyes include the Siamese, Balinese, Himalayan, Persian, Airman and Javanese. There is also the very rare Dojos Azures breed, which can produce cats with dark coats and blue eyes.

White cats have a genetic makeup similar to albino humans, who lack pigment; this gives them some vulnerabilities, like sensitivity to UV light. In that case, Dr. Lyons says a hearing impairment may happen in just one ear, particularly on the side of the face with the blue eye.

The hue begins to change to the kitten’s true eye color at around 6 or 7 weeks of age. If you want to know if a cat with blue eyes is deaf, stand back several feet behind her and clap or make another loud noise.

Cats feel non-auditory vibrations very well though, so stand on the other side of the room to allow enough space, Dr. Lyons says. Those blue eyes of your feline fur baby are so beautiful, but that eye color she inherited could signal a link to a health condition.

Veterinarians have realized a link exists between your fur baby’s beautiful blue eyes and a few health issues, some of which include deafness. If your baby’s eyes stayed blue, you’ll need to talk to the vet about the implications for her hearing.

All kittens are born with nominally blue eyes, and some cats retain this apparent hue throughout life. The range of blues that we see observe in cat eyes are a result of refracted light, rather than a function of pigmentation.

Upon exiting the womb and entering the whelping box, a newborn kitten ‘s eyes are sealed shut and functionally useless. Like their coatless bodies and closed ears, a kitten’s eyes are not fully developed at birth.

These activities provide the fuel and raw materials for growth across the board, including preparing the eyes for sight. Part of kitten eye maturation is developing the ability to process light and interpret sensory input.

How many melanocytes there are and how much melanin they yield determines the final color and its depth or intensity. Like their fascinating coat-color distribution, the blue eyes in color point cats result from a form of partial albinism.

You can distinguish between a white cat and a true albino by the eyes, which range from pale blue to pink. What’s truly remarkable is that when a kitten is born, she is functionally blind, and her eyes grow and develop along with the rest of the body.

From the moment a kitten is born until he can safely undergo a spay or neuter procedure, a number of developmental changes occur. Since many of us only adopt cats after they’ve been weaned, we completely miss this period of rapid maturation.

Eye color change is one of the last processes we can actually observe if the timing is right and if the kitten’s pace of development is slow enough. Once a cat is physically mature, her eyes should remain a consistent color throughout life.

If you notice a dramatic change in eye color in a grown cat, it could signal a number of health issues, ranging from eye infections and uveitis to leukemia and feline immunodeficiency virus.
