Introduction:
If you have ever come across a feline friend with two different eye colors, you might have wondered what this unique characteristic is called. Cats with two different eye colors are commonly referred to as “odd-eyed” cats. This mesmerizing trait is not only visually striking but also holds a fascinating scientific explanation. In this article, we will explore why some cats have this captivating feature and delve into the genetics behind it. So, get ready to unravel the mysteries of these enchanting creatures and discover the wonders of odd-eyed cats.
What breed of cat has two different eyes?
There is a specific breed of cat known for having two different eye colors, which is called the “Oriental Shorthair.” This breed is quite unique and visually striking due to its heterochromatic eyes. One eye can be blue while the other can be green, yellow, or even amber. This characteristic is caused by a gene mutation that affects the pigmentation of the iris.
The Oriental Shorthair is a medium-sized cat with a sleek and slender body. It has a wedge-shaped head, large ears, and a long, elegant tail. Its coat can come in various colors and patterns, including solid, tabby, tortoiseshell, and colorpoint.
It is important to note that having two different eye colors is not exclusive to the Oriental Shorthair breed. Some cats of other breeds or mixed-breed cats may also exhibit this trait. However, when people specifically refer to a breed with this characteristic, they are usually referring to the Oriental Shorthair.
If you are considering adopting an Oriental Shorthair or any cat with two different eye colors, it’s important to remember that eye color alone does not determine a cat’s personality or health. Each cat is an individual, and their behavior and health depend on various factors such as genetics, environment, and care.

How rare are heterochromia cats?
When it comes to heterochromia in cats, it is important to understand that it is a relatively rare occurrence. Heterochromia refers to a condition where a cat has two different colored eyes. While this condition may seem unique and captivating, it is estimated that only around 1% of the feline population has heterochromia.
Here are some key points to consider:
1. Definition of Heterochromia:
– Heterochromia is a genetic trait that affects the pigmentation of the iris in one or both eyes of a cat.
– It results in two different eye colors, such as one eye being blue and the other being green.
2. Causes of Heterochromia:
– Heterochromia can be either congenital (present at birth) or acquired later in life due to injury or illness.
– Congenital heterochromia is usually the result of genetics and can occur in various cat breeds.
– Acquired heterochromia may be caused by trauma, inflammation, or certain medical conditions.
3. Types of Heterochromia:
– Complete heterochromia: One eye has a completely different color from the other eye, such as one eye being brown and the other being blue.
– Sectoral heterochromia: Only a portion of one eye has a different color, creating a distinct pattern within the iris.
4. Breeds Prone to Heterochromia:
– While heterochromia can occur in any breed, certain breeds are more likely to have cats with this condition.
– Examples include Turkish Van, Turkish Angora, Japanese Bobtail, and some Siamese and Persian cats.
– However, it is crucial to note that not all cats from these breeds will have heterochromia.
5. Health Implications:
– In most cases, heterochromia does not cause any health problems or affect a cat’s vision.
– However, it is essential for cat owners to monitor their cat’s eye health and consult a veterinarian if any unusual symptoms occur.
What are odd-eyed cats called?
Odd-eyed cats, also known as heterochromatic cats, are feline companions that possess eyes of different colors. This phenomenon occurs due to a genetic mutation that affects the pigmentation of the iris. One eye may be blue, while the other can be green, gold, or even brown.
The term “odd-eyed” is used to describe these cats because their eyes appear unique and striking. It is a fascinating characteristic that adds to their overall charm and appeal. The contrast between the different eye colors often creates a mesmerizing effect that captivates cat lovers.
The main reason behind this distinctive feature is a condition called complete heterochromia. It results from the presence of two different versions of the white spotting gene (W gene) in a cat’s DNA. One version causes the eyes to be blue, while the other causes them to be non-blue, which can include colors like green, amber, or yellow.
It’s important to note that not all cats with different-colored eyes are considered odd-eyed cats. In some cases, cats may have one eye that is partially blue and partially another color. This condition is called partial heterochromia and is different from complete heterochromia seen in odd-eyed cats.
Odd-eyed cats can come in various breeds and mixes, including Turkish Van, Turkish Angora, Japanese Bobtail, and even domestic shorthairs. However, it’s worth mentioning that odd-eyed cats are relatively rare. The genetic mutation responsible for this unique trait occurs sporadically and is not limited to specific breeds.
Furthermore, the presence of odd-eyed cats is not solely limited to domestic cats. Other animals, such as dogs and horses, can also exhibit heterochromia.
In summary, odd-eyed cats are feline companions with eyes of different colors, known as heterochromia. This genetic mutation creates a visually striking appearance that distinguishes them from other cats. Whether they have one blue eye and one green eye or any other combination, these cats are adored by cat enthusiasts for their exceptional and captivating feature.
