Are Siamese Cats Cross Eyed? (VET Answer)

Have you heard that Siamese cats are cross-eyed? The answer is no! If a Siamese cat has one eye that appears to be looking up, down or sideways, this does not mean it is cross-eyed. 

There are several reasons why your Siamese kitty might have one pupil larger than the other.

Are Siamese Cats Cross Eyed?

The answer to this question depends on how you define the terms “crossed” and “eyed.” Siamese cats are born with normal, symmetrical eyes that gradually become more and more crossed as they age. 

However, their eyes do not cross in the same way that humans’ eyes do: human vision is based on a single image projected onto each retina at right angles to each other; Siamese cat vision is based on two images being projected onto both retinas at different angles the result being that they see things differently than humans do.

This genetic abnormality can cause some behavioral problems in Siamese kittens (they have difficulty focusing, for example), but it typically doesn’t affect their overall health. 

If you’re worried about your cat’s crossed eyes becoming problematic later in life (perhaps because of an eye condition like glaucoma or blindness), talk to your vet about possible treatments for his or her symptoms before too much damage has been done!

What Color Are The Eyes Of A Siamese Cat?

Siamese cats have blue eyes, though they are not always cross eyed. The eyes of a Siamese cat can be any shade of blue, from light to dark.

Some Siamese cats have one blue eye and one green eye, while others may have two different shades of blue or grayish-blue.

Siamese cats can see out of their crossed eyes just fine! The reason for the crossed eye appearance is due to a defect in development during gestation that causes an abnormal alignment between the left and right halves of their brains (called cerebral herniation).

What color are the eyes of a Siamese cat?Siamese cats typically have striking blue eyes.
Do all Siamese cats have blue eyes?Yes, blue eyes are a defining characteristic of Siamese cats.
Are there any Siamese cats with different eye colors?While rare, there are some Siamese cats with eye color variations, such as odd-eyed Siamese with one blue eye and one different-colored eye.
Are Siamese cat eye colors permanent?Yes, the blue eye color of Siamese cats is permanent and does not change over time.
Can the eye color of Siamese cats change?The eye color of Siamese cats does not change, although kittens may have lighter eyes that darken as they mature.

Are They Always Cross Eyed?

Some Siamese cats are born with normal eyes, but some develop crossed eyes later in life. Some never develop crossed eyes at all. 

If you adopt a Siamese cat from a shelter or rescue organization, it’s impossible to know which category your new pet will fall into until they’re older and have developed the condition themselves.

It depends on the cat’s genes and their environment as well as whether other family members have had this issue before them!

The eternal question for Siamese cat owners is whether to let them roam outdoors or keep them as indoor companions. If you’re pondering this decision, our comprehensive guide on Are Siamese Cats Indoor or Outdoor Cats? offers valuable insights into the considerations and benefits of both options, helping you make an informed choice for your Siamese companion.

Can They See Out Of Their Cross Eyes?

It’s true that the way Siamese cats see might seem odd compared to how we see, but it’s not as bad as it may seem at first glance. In fact, they can see out of both eyes just like any other animal (including humans)!

Binocular vision is when an animal has two separate eyes that work together to give them depth perception and three-dimensional vision. 

In contrast, monocular vision means they have only one eye and rely on binocular cues from their head movements to give them depth perception. 

Animals with binocular vision will generally move their heads back and forth or side to side in order to perceive depth; this is called head bobbing or neck extension.

Why Do Siamese Cats Have Crossed Eyes?

If you’ve ever seen a Siamese cat, you may have noticed that they have crossed eyes. The reason for this is because of a genetic mutation that causes their pupils to be oval shaped rather than round. This trait is known as heterochromia iridis and it’s a recessive gene. 

This means that if both parents carry the gene, there is an increased chance for their offspring to inherit it too!

If your Siamese cat has heterochromia iridis (or cross eyes), then there’s no need to worry! Although some people believe that their cats are blind or suffer from vision problems due to their appearance, this isn’t actually true at all; although sometimes having one blue eye and one green eye can be confusing for humans who can only see in black & white… but cats aren’t colorblind so all they need are two good peepers!

What causes crossed eyes in Siamese cats?Genetic factors and a specific gene mutation can cause crossed eyes.
Is it common for Siamese cats to have crossed eyes?Yes, crossed eyes are relatively common in Siamese cats.
Are Siamese cats born with crossed eyes?No, Siamese cats are not typically born with crossed eyes.
Do crossed eyes in Siamese cats affect their vision?In most cases, crossed eyes do not significantly impact their vision.
Can crossed eyes in Siamese cats be corrected?There is no known cure, but corrective measures can improve the appearance.

Is It True That Siamese Cats Are Cross Eyed?

No. Siamese cats are not born with cross eyes. Cross eyes develop as the cat grows, and at some point in the cat’s life (usually around two years old), the condition becomes permanent. The condition is called “strabismus,” which means that one or both of their eyes don’t line up properly. 

This is a condition that affects both humans and cats alike, though it is much more common in people than it is in cats!

How Do I Know If My Cat Is Cross Eyed?

To determine if your cat is cross-eyed, look at their eyes. If you can’t see their pupils, then the iris (the colored part of an eye) will tell you if they are cross-eyed or not. If you can see their pupils, then you’ll need to look at the iris for further evidence.

A Siamese cat with one blue eye and one green eye would have two different colored eyes one blue and one green but this isn’t necessarily a sign that your Siamese is cross-eyed; he or she might just be born with heterochromia iridum (or “mismatched” eyes). 

This condition happens when there’s too much melanin in one area of the eye—and since melanin controls skin coloration as well as eye coloration, it’s possible for some cats’ eyes to be two different shades of brown while others are two different shades of blue! 

Heterochromia is considered normal among Siamese cats; however, any other type of cross-eyedness in these felines may indicate something wrong medically speaking…

Are Siamese Cats Born With Crossed Eyes?

No, Siamese cats are born with crossed eyes. The reason for this is that Siamese kittens have a genetic defect on their X chromosome which causes them to be born with the blue and brown eyes that we see in the adult cat. 

This genetic defect also causes the kitten’s pupils to remain dilated (enlarged) from birth. The Siamese cat’s pupils will not constrict as they mature but they can still see out of both eyes even though they appear crossed because one eye is pointing more towards you than the other one.

Are Siamese cats born with crossed eyes?No, Siamese cats are not typically born with crossed eyes.
When do Siamese cats’ eyes start to cross?Siamese cats’ eyes may start crossing at around 6 to 8 weeks of age.
Do all Siamese cats have crossed eyes?No, not all Siamese cats have crossed eyes. It can vary within the breed.
Can crossed eyes in Siamese cats be fixed?In some cases, corrective measures can be taken to improve the alignment of crossed eyes in Siamese cats.
What should I do if my Siamese kitten has crossed eyes?If you notice crossed eyes in your Siamese kitten, consult a veterinarian for proper evaluation and guidance.

What Type Of Cat Is Cross Eyed?

To understand what type of cat is cross-eyed, first we have to look at the history and origin of this unique breed. Siamese cats were first imported into the United States in 1878 by a man named Major Henry Menard. 

They were then bred with other breeds, including Burmese and Abyssinians, to create even more diverse types of cats.

Crossed eyes are not considered a defect in Siamese cats; it’s actually a natural trait for them! The gene that causes crossed eyes has been around since ancient times, but was only discovered recently due to improved technology that allows scientists to study DNA more easily than ever before.

What’s The Scientific Name For A Cross Eyed Cat?

The name of this condition is “heterochromia iridum,” which means “differently colored iris.” It’s not harmful to your kitty at all, but it can make her look pretty weird! If you happen to notice that your cat has one blue eye and one green eye, don’t worry about it this can be a genetic trait passed down from parents with the same condition.

The reason why Siamese cats are so frequently born with crossed eyes is because they’re most likely related to another breed which already exhibits this feature. 

Siamese cats have been bred over hundreds of years by humans who wanted them for their unique looks! Because their gene pool has been limited for so long, breeding two Siamese cats together will often result in offspring who also have crossed eyes (and other traits).

Siamese cats are renowned for their distinctive vocalizations, captivating anyone within earshot. If you’ve ever wondered what a Siamese cat sounds like and what their vocalizations mean, our article on What is a Siamese Cat Sound Like? deciphers their melodic language, giving you a glimpse into the world of Siamese cat communication.


It can be easy to think that Siamese cats are always cross eyed, but this is not always the case. These cats can have one blue eye and one green eye or one blue eye and one brown eye. They may also have a combination of these colors. 

Some cats have both eyes pointing in the same direction while others have one slightly rotated upwards compared to the other eye.
