Between the age of three to eight weeks, kittens’ eyes begin to change to colors ranging from green, yellow and orange to amber, copper and brown. Uveitis is the inflammation of the veal tract of the eye, which consists of the iris, biliary body and choroid.

Not all cats with liver shunts have copper colored eyes. If your cat’s eye color changes suddenly or over a period of time, consult with your veterinarian as soon as possible.

“Every stare is like a hook” to quote the Ray Stevens' song “Cat's Eye”. Stephen King wrote a spooky anthology story called Cat's Eye about a heroic cat who saves his young mistress from an evil troll.

The final scene in the epic music video “Thriller” is a close up of Michael Jackson's face with feline eyes as Vincent Price laughs evilly. Melanin comes from melanocytes, the number of which determines the cat's eye color.

Wild cats in temperate regions such as lynxes and bobcats typically have hazel eyes. However, the eye color of domestic cats can vary from blue to green to yellow, orange and a copper tone often mistaken for brown.

This means a dark furred cat can have light eyes and vice versa. Seven to ten days later, the eyes will start to open and will be a cloudy shade of blue.

At the age of ten weeks, the kitten's eyes will have vision as good as an adult cat. It has two layers that carry the color promoting cells that are known as melanocytes.

The colors can be blue, yellow, green, gold, copper, red or amber. Up to 70% of cats with odd colored eyes can hear perfectly normally.

David Bowie's “Cat People” mentions “eye so green I can stare for a thousand yards.” Green eyes are often associated with mystical powers and are the color most associated with cats. The Russian Blue is known for emerald green eyes contrasting with slate gray fur.

This condition can be inherited genetically or congenital due to development defect. Like with the previously mentioned David Bowie, heterochromia may be acquired through illness, injury or medication.

The condition is most commonly found in ecstatic white cats that have one eye in blue and the other being orange, yellow, copper, hazel or green. Persians, sphinxes and Oriental short hairs are also prone to mismatched eyes.

The black tipped chinchilla cat will have eyes in a deep turquoise color. An albino cat will rarely have the pink eyes associated with most animals with albinism.

As an albino has no melanin, this is not so much an eye color as light reflecting the blood flow in the back of the retina. A white cat with sapphire or cornflower blue eyes may not be an albino.

Albino cats are technically not white, they simply have no melanin meaning they have no color at all. A cat with orange eyes that were previously another color can mean an inflammation known as uveitis.

The cause for this may be diabetes, high blood pressure, eye trauma, metastatic tumors, a fungal or bacterial infection or a viral disease such as feline herpes, Fell, FIV, or FIP. If they look darker than usual it may be due to red blood cell build up.

Glaucoma is an ocular condition accompanied by increased pressure in the eye. The usual symptoms to look for are a cloudy, milky white eye color.

A reddish-brown copper color like a new penny can be beautiful, if it is a natural trait of the cat. Do keep in mind that not all cats that have liver shunts will have copper colored eyes.

In any case, if your cat is well past the age of three months and her eye color suddenly changes there may be a health problem and you should take her to a vet. If one pupil seems more dilated than the other, this is also caused for concern as it may be a sign of a concussion, brain hemorrhage, aneurysm or optic neuritis.

While they can’t see in total darkness, they can adjust better to low light conditions than humans can. However, along with better night vision and the ability to see ultraviolet light, the cat can also see quick moving objects better than a human.

This could explain why your cat is more likely to eat a treat if you fling it across the room than if you just lay it at her feet. Cat eye color is due to the presence of melanin, which itself is the result of genetics.

The eye is blueish as it first starts to develop, gradually becoming the final adult color at three months. If your adult cat’s eyes suddenly change color or appearance medical intervention will be necessary.

Pay close attention to them and take note if they suddenly look different one day. With care and attention, your cat could have ideal vision for the rest of her life.

An unusual and attractive look is the chromatic, or dichroic, eye, usually seen in white cats. In fact, the major contributors to the ultimate color of a cat's eyes are blue refraction, iris pigmentation and breeding.

As for blue eyes in adulthood, that's either part of the pointed gene (like Siamese have), or it's a trait of a breed called Dojos Azures, which all have blue eyes in adulthood. Once in a while, you'll see a cat with a striking condition called heterochromia irides, which means irises that are different colors.

Kittens are born with two blue eyes and over the following weeks, melanin moves into the iris and causes a color change to green, yellow, or brown. Sometimes a bit of melanin moves into one iris but doesn't completely change the eye's color.

If one of both of your cat's eyes begin to change color when she is older rather than in the first few weeks after birth, there may be a problem. So if you are blessed to have a cat with two different eye colors in your life, consider it just another way in which your sweet kitty is unique and special.

Treatments usually consist of applying topical medication to the ulcer as well as administering antibiotics to treat or prevent secondary bacterial infections. Some treatment options include antibiotics and anti-inflammatory drops, antiviral therapy or removal of the affected tissue followed by a corneal graft to protect the cornea as it heals.

Mature cat eyes take their hue from the amount of pigment cells in the iris, known as melanocytes, that are present during the processes of growth and development. What appears blue to us is simply a reflection of the transparent parts of a cat’s eyes.

Let’s turn our attention now to why cat eye color can change or appear inconsistent. While it is interesting and aesthetically intriguing, cats with different colored eyes are not unusual.

A cat’s mature eye color tends to develop and stabilize over the first 3 months of life. Changing eye color as an adult or mature cat, on the other hand, is not only abnormal, but it can also be a sign of dangerous health issues.

Uveitis, or inflammation of the UVA, can cause a cat’s eye color to change significantly and suddenly. Uveitis in cats is rarely a problem of its own; it tends to be a symptom of any number of other conditions, all of which require veterinary attention and treatment.

Cats with orange, gold, or yellow eyes, on the other hand, are more likely to shine green in the light. As previously mentioned, cat eye colors are dependent on the amount of melanin in their irises.

Known as complete heterochromia, this condition is most frequently found in white cats, however, it can affect all kinds of cats regardless of fur color or breed, so long as they carry a gene known as the white spotting gene.

While they have no other known health issues, if you own an albino cat, be aware that sunlight could damage their very sensitive eyes. As mentioned above, white cats primarily have lighter colored eyes as a result of the amount of melanin, or lack thereof, in their genes.

Many white cats can have yellow, copper, green, or blue eyes. Because many white cats will have blue eyes, which means less melanin, they are more sensitive to sunlight.

If your cat is white with extremely pale blue eyes, she is probably albino. Unfortunately, science has found that cat eye colors do have a correlation with certain health issues.

However, we should be aware of many misconceptions about health issues as related to eye color in cats. However, if a white kitten has even a small amount of color variation on its fur, whether it is a speck, a spot, or a patch, the chances of deafness are significantly reduced.
