Maine Coon Eyes: Colors, Shape & Blue Eyes Explained
Maine Coon eyes are one of the breed’s most striking features. They are large, expressive, and set within a powerful face framed by a square muzzle, prominent whisker pads, and often dramatic coat markings. But what colors can Maine Coon eyes actually be? Can they have blue eyes? Why do some look as though they are wearing eyeliner? And when does a change in the eyes warrant a trip to the veterinarian?
After living with three pedigree Maine Coons for more than 14 years, I’ve also seen how different the eye area can look from one Maine Coon to another.
Quick Answer
Maine Coon eyes are typically large, expressive, slightly oval, and set wide apart. Common adult eye colors include:
Green
Gold
Green-gold
Copper
White Maine Coons may also have blue eyes or odd eyes, where the two eyes are different colors.
Maine Coon kittens usually begin life with blue-looking eyes, but their permanent color develops as they grow. Eye color, eye shape, or dark markings around the eyes can contribute to a Maine Coon’s appearance, but none of these characteristics alone proves that a cat is a Maine Coon.

If you want to understand how the eyes fit into the breed’s overall appearance, my guide explaining what a Maine Coon is covers the full breed type.
1. What Do Maine Coon Eyes Look Like?
Maine Coon eyes are generally large, wide-set, and slightly oval. The Cat Fanciers’ Association Maine Coon standard describes large, expressive eyes that are set well apart, while the International Cat Association Maine Coon profile also emphasizes the breed’s characteristic alert expression.
When a Maine Coon is particularly interested or excited, the eyes can appear almost round. However, the overall appearance comes from much more than the eyes themselves. They sit within a large head with prominent whisker pads and a strong square muzzle, which helps create the distinctive Maine Coon expression.
2. What Color Eyes Do Maine Coons Have?
Maine Coon eyes are commonly:
- Green
- Gold
- Green-gold
- Copper
In real life, the colors are not always easy to place into neat categories.
A cat may have yellow-green eyes, rich amber-gold eyes, or a shade that looks different depending on the light. There is also no requirement for a particular eye color to match a particular coat color in most Maine Coons. That means brown tabbies, blue Maine Coons, black Maine Coons, and many other colors may have green, gold, copper, or intermediate shades.
You can see just how broad the breed’s coat-color range is in my Maine Coon colors and patterns guide.
3. Can Maine Coons Have Blue Eyes?
Yes, but blue eyes are primarily associated with white Maine Coons.
Breed standards allow white Maine Coons to have:
- Blue eyes
- Non-blue eyes
- Odd eyes
Odd-eyed cats have two different-colored eyes, such as one blue eye and one gold or green eye.
Blue eyes should therefore not be treated as a typical Maine Coon characteristic across the whole breed. They also do not prove that a fluffy white cat is a Maine Coon. Many other cats can have blue eyes.
If you’re particularly interested in this combination, my white Maine Coon guide covers white coat genetics, appearance, and related considerations in more detail.
4. Do Maine Coon Kittens Have Blue Eyes?
Maine Coon kittens, like other kittens, usually begin with blue-looking eyes. Their permanent eye pigment has not fully developed at birth. As pigmentation increases, the eyes gradually begin changing toward their adult shade.
During this transition, you may see colors that look:
- Blue-gray
- Gray-green
- Yellow-green
- Muddy or mixed
So a young Maine Coon kitten having blue eyes does not mean those eyes will remain blue. For most non-white Maine Coons, the final color develops as the kitten grows.
5. Why Does My Maine Coon Look Like It Is Wearing Eyeliner?
Sometimes the most striking thing about a Maine Coon’s eyes is not the iris color at all. It is the fur immediately surrounding the eyes. This is particularly noticeable in patterned Maine Coons.
Mika’s Black Eyeliner
Mika looks almost as though somebody has drawn black eyeliner around his entire eye. Immediately below it, however, his fur becomes much lighter. That lighter area is most obvious underneath each eye but effectively creates a contrasting border around the eye area. The combination makes his eyes look even more outlined.
Bali also has lighter shadowing around his eyes, although his overall effect is softer than Mika’s. My first Maine Coon, Pippin, also had prominent dark markings around his eyes too.
These effects come from facial coat patterning and color contrast, rather than the actual structure or color of the eye. Tabby facial markings in particular can create very dark lines around the eyes, nose, and forehead. My tabby Maine Coon guide explains these patterns in much more detail.
The important point is that a cat looking as though it is wearing eyeliner is not, by itself, a Maine Coon identifier.
6. Does Eye Color Prove A Cat Is A Maine Coon?
Eye color is one of the weaker characteristics for identifying breed ancestry.
A cat can have:
- Green eyes
- Golden eyes
- Large eyes
- Dark eye markings
- A very expressive face
without having any Maine Coon ancestry at all.
Instead, Maine Coon identification involves looking at the whole cat, including body structure, muzzle shape, ears, coat, tail, paws, and known ancestry. Even then, appearance can establish resemblance rather than pedigree.
If you have a cat of unknown ancestry, my guide on how to tell if your cat is part Maine Coon explains which characteristics are useful and which are commonly overinterpreted.
7. Can Maine Coons Have Odd-Colored Eyes?
White Maine Coons can have odd eyes, meaning the two irises are different colors. For example, a cat might have:
- One blue and one green eye
- One blue and one gold eye
- One blue and one copper-colored eye
This condition is known as heterochromia. It can be extremely striking, particularly against a pure white coat, but it is a normal color variation rather than a separate Maine Coon type.
8. Do Maine Coon Eyes Change Color With Age?
The biggest eye-color change occurs during kittenhood. Once the adult iris color has developed, dramatic changes are not expected simply because a Maine Coon is getting older. Lighting, pupil size, and surrounding coat color can make an established eye color appear different. But a new physical change to an adult cat’s eye deserves more attention.
Cloudiness, redness, unequal pupils, or an obvious color change should not simply be dismissed as aging.
9. Eye Problems In Maine Coons
Maine Coons can develop many of the same eye conditions that affect other cats. These include problems such as:
- Conjunctivitis
- Corneal scratches or ulcers
- Uveitis
- Eye infections
- Cataracts
- Glaucoma
- Retinal disease
- Trauma
For example, VCA Animal Hospitals’ guide to conjunctivitis in cats explains that inflamed eyes may become red, watery, swollen, or produce discharge. Some eye conditions are relatively minor, while others can threaten vision if treatment is delayed.
My article on blindness in Maine Coon cats looks specifically at possible causes of vision loss, while my broader Maine Coon health and wellness guide covers the breed’s major health considerations.
10. When Should You See A Veterinarian?
Eye problems are worth taking seriously because cats can hide discomfort surprisingly well. Contact a veterinarian promptly if you notice:
- Persistent squinting
- Redness
- Swelling
- Excessive watering
- Yellow, green, or thick discharge
- A cloudy surface
- One pupil suddenly becoming a different size
- An eye being held closed
- Repeated pawing or rubbing
- An obvious injury
- Sudden difficulty seeing
A small amount of normal dried discharge in the corner of an otherwise comfortable-looking eye is very different from a cat suddenly squinting, rubbing, or developing redness.
If something about your Maine Coon’s eye has changed suddenly, it is safer to have the cause assessed than to assume it is simply part of the breed.
11. Are Maine Coon Eyes Different From Other Cats?
There is no eye feature that exists exclusively in Maine Coons. What makes their eyes distinctive is the combination of characteristics.
Their large, expressive eyes sit within a face that may also have:
- A strong square muzzle
- Prominent whisker pads
- Large ears
- Heavy facial furnishings
- Dramatic tabby or other coat markings
This combination can make a Maine Coon’s expression look especially intense, gentle, curious, or even slightly wild. That is exactly what I see among my own cats. Mika’s dark eyeliner-like markings and pale surrounding fur make his eyes look incredibly defined. Bali’s lighter border produces a softer effect, while Pippin’s darker eye markings gave him another completely different expression.
All three are pedigree Maine Coons, yet the eye area looks noticeably different on each cat. That is a useful reminder that there is not one single Maine Coon eye “look.”
Frequently Asked Questions
What Color Eyes Do Maine Coons Have?
Most Maine Coons have green, gold, green-gold, or copper-colored eyes. White Maine Coons may also have blue or odd-colored eyes.
Do Maine Coon Kittens Have Blue Eyes?
Usually, yes. Maine Coon kittens begin with blue-looking eyes, but their permanent eye color develops as pigmentation increases.
Can A Maine Coon Have Blue Eyes?
Yes. Blue eyes are accepted in white Maine Coons, as are odd eyes. Blue eyes are not, however, a typical characteristic of Maine Coons of every coat color.
Why Does My Maine Coon Look Like It Has Eyeliner?
Dark coat markings immediately surrounding the eyes can create an eyeliner effect, particularly in tabby cats. Lighter fur surrounding those dark lines can make the contrast even stronger.
Does Eye Color Tell You If A Cat Is A Maine Coon?
Eye color and markings can contribute to a Maine Coon-like appearance, but neither can prove pedigree ancestry.
Conclusion
Maine Coon eyes are large, expressive, and one of the features that give the breed such a distinctive face.
Most adults have green, gold, green-gold, or copper-colored eyes, while white Maine Coons may also have blue or odd eyes.
The surrounding coat can be just as striking as the eyes themselves. Mika’s dark eyeliner-like markings and pale border, Bali’s lighter shadowing, and Pippin’s darker eye markings show how dramatically the eye area can vary even among pedigree Maine Coons.
There is no single Maine Coon eye color or marking that proves breed ancestry; it is the overall cat, and ultimately its documented ancestry, that matters.
