Big Eyes and Unique Cat Breeds: A Comprehensive Guide

Cat lovers everywhere know that the eyes are the windows to their feline’s soul. And what a sight to behold! With varying colors and shapes, cat eyes can express emotions ranging from love and contentment to annoyance and aggression.

In this article, we will delve deeper into the importance of cat eyes and provide you with a comprehensive guide of cat breeds with unique eye characteristics. Unique Feature: Eye Size

When it comes to eye size, some cat breeds top the list with their big, anime-cartoonish eyes.

Persian cats, for example, are known for their small, flat faces and round eyes that come in bright blue, green, and copper. Similarly, Tonkinese cats have large, weepy eyes that come in aqua, sky blue, violet, and gold tones.

Singapura cats, the smallest cat breed in the world, have almond-shaped eyes that come in hazel, green, and yellow hues. Not all cats, however, have larger eyes.

Some breeds, like the Siamese and Oriental Shorthair, have more triangular-shaped heads, making their eyes appear smaller. And while eye size can affect a cat’s appearance, it doesn’t necessarily impact their health or personality.

So whether your fur baby has big, soulful eyes or smaller, almond-shaped ones, love them all the same!

Communication Through Eyes

Cats are known to communicate through body language, and their eyes play a significant role in that communication. Here are a few eye-related signs to look out for:


Pupil size – When a cat is in a good mood or feels content, their pupils will be constricted, making them appear thinner. Conversely, when they are frightened or agitated, their pupils will dilate, making them appear larger.

2. Blinking – Slow blinking, also known as “cat kisses,” is an expression of love and affection.

When your cat blinks slowly at you, it’s their way of showing that they trust and feel comfortable around you. 3.

Staring – When a cat stares intently into your eyes, they are expressing dominance or aggression. This stare down is a common behavior among felines and is often a way of establishing hierarchy among cats.

Eye Abnormalities

While eye abnormalities can make a cat’s appearance unique, there are some instances where they can be a warning sign of health problems. Here are a few abnormalities to look out for:


Heterochromia – This is a condition where a cat has two different-colored eyes. While it can be a unique feature of a cat’s appearance, it can also be a warning sign of eye-related illnesses like glaucoma or cataracts.

2. Odd-eyes – This refers to cats that have eyes that are different colors within the same eye.

While it can be a unique feature, it can also be a warning sign of health problems. 3.

Warning signs – If you notice any sudden changes in your cat’s eye size, pupil shape, or any unusual discharge, it’s best to take them to the vet for a check-up.

Breed Characteristics

Every cat breed has its unique characteristics, including those related to their eyes. Here are a few breeds with notable eye-related traits:


Cataracts – Persian cats tend to develop cataracts, a clouding of the eye lens that can cause vision loss. 2.

Burmese Cats – Burmese cats are known for their glowing green or gleaming gold eyes. They are an active, vocal breed and are natural climbers.

3. Siamese and Burmese Cross – Tonkinese cats have rounded eyes that come in a wide range of colors.

They are a cross between Siamese and Burmese cats and are known for their playful and affectionate personalities.

Breeds to Avoid Due to Macrophthalmia

If you are in search of a new feline friend, it’s important to do your research and choose a breed carefully. Unfortunately, some breeds are more prone to certain genetic conditions than others.

One such condition is macrophthalmia, a congenital condition characterized by abnormally large eye(s) that can lead to lens detachment (luxation), cataracts, glaucoma, discomfort/pain, and even blindness. In this article, we will explore some breeds that are prone to macrophthalmia and share insights into this genetic error.

What is Macrophthalmia? Macrophthalmia is a rare congenital condition that results in larger than average feline eyes.

Often caused by a genetic error, the condition can lead to various eye-related health issues that can affect the cats comfort and well-being. While larger eyes may seem like an attractive trait in cats, macrophthalmia can lead to several eye problems, including lens detachment (luxation), cataracts, glaucoma, discomfort/pain, and even blindness.

Early detection and treatment by veterinary specialists are crucial to prevent further complications.

Breeds Prone to Macrophthalmia

Here are some feline breeds that are prone to the condition:

1. Persian Cats – Persians are one of the most popular breeds in the world but are also known to be prone to macrophthalmia.

The breed’s characteristic flat face and round eyes make them more susceptible to eye issues, including this congenital condition. 2.

Siamese Cats – Siamese cats are a well-known feline breed with a unique appearance and intense blue eyes. They can develop macrophthalmia due to various factors, including their breeding, genetics, or environmental factors.

3. Himalayan Cats – Himalayan cats are another breed that is prone to macrophthalmia, which can cause significant eye discomfort for the cat if left untreated.

4. Devon Rex – The Devon Rex is a small, curly-haired feline breed that can also develop macrophthalmia as a result of a genetic error.

5. Sphynx Cats – Hairless and often referred to as “aliens” due to their unusual appearance, sphynx cats are susceptible to several genetic conditions, including macrophthalmia.

Macrophthalmia Symptoms

Macrophthalmia in cats is often easy to spot. The most common symptoms include:


Abnormally large eyes – this is usually a tell-tale sign of macrophthalmia in felines. 2.

Visual Impairment – While cats have excellent night vision, their sight is not perfect. However, cats with macrophthalmia can experience visual impairments.

3. Red or swollen eyes – If the cat’s eyes appear red or swollen, it may be an indication of macrophthalmia.

4. Pupil size changes – If a cat’s pupils are continually dilated or constricted, it could be due to macrophthalmia.

5. Discomfort or pain – Cats with macrophthalmia can experience eye discomfort or pain due to the increased pressure from the large eye size.

Treatment for Macrophthalmia

If you suspect or receive a diagnosis of macrophthalmia, its best to consult a veterinary specialist. Early detection can help prevent the condition from worsening, leading to more severe eye issues such as blindness.

Depending on the severity of the condition, surgery may be necessary to alleviate discomfort or remove the affected eye if necessary. In some instances, the cats eyes may need frequent monitoring from a veterinary specialist.

This frequent monitoring ensures that early detection and proper treatment can be performed to ensure the cats quality of life is maintained. Unfortunately, for cats with severe macrophthalmia, the removal of the affected eye may be necessary.

While this may sound distressing, removing the affected eyeball is usually done for the health and ultimate comfort of the cat.


While macrophthalmia is a rare condition, it is one feline owners should be aware of, especially if considering a breed prone to the condition. Watch for symptoms, ensure that the cat is examined regularly by a veterinary specialist, and keep your feline companion as comfortable as possible.

If left untreated, complications can lead to a range of eye issues, including visual impairment and blindness. By taking necessary precautions, feline owners can help ensure their furry friends lead a comfortable and happy life.

In summary, macrophthalmia is a rare congenital condition that can lead to abnormally large eyes and various related eye problems such as lens detachment, cataracts, glaucoma, discomfort, and even blindness. Persian, Siamese, Himalayan, Devon Rex, and Sphynx are among the feline breeds prone to the condition.

Early detection, regular monitoring by veterinary specialists, and proper treatment are essential to enhance the comfort and well-being of affected cats. Removing the affected eyeball may be necessary in severe cases.

Hence, its crucial for feline owners to be aware of the symptoms and consider the breeds susceptibility to the condition when adopting cats. The health and care of the feline friend should always be a top priority.
