Cross-eyed Siamese Cats were first documented in the early 1900s when two Siamese cats with crossed eyes were born in a litter of five. One of the cats was later sent to a breeding farm, and many kittens likely descended from them throughout the years due to their desirable trait.
The cross-eyed trait is caused by a genetic mutation that affects muscle control around the eye, causing them to appear crossed. They are sometimes called walleyed or walleyed Siamese cats and can have different degrees of crossing depending on the mutation’s severity.

The breed is beloved for its unique appearance and playful nature, which makes it an excellent companion for households with children or other animals. They have become increasingly popular as more people learn about their unique features, making them one of the most sought-after cats breeds worldwide.

What causes crossed eyes in Siamese cats?
Crossed eyes, or strabismus, is a condition in which the eyes of a cat are misaligned and do not focus on the same point. Siamese cats are particularly prone to this condition due to an inherited gene that causes their eye muscles to be weaker than usual.
In some cases, crossed eyes can be present at birth, while in others, the condition develops as the cat ages. Treatment typically involves a combination of vision drops to help relax the muscles and surgery to realign the eyes.
Regardless, pet owners must take their Siamese cats in for regular checkups with a veterinarian to ensure that any sign of crossed eyes is caught early. By doing so, pet owners can help their cats live a healthy and happy life.
If your Siamese cat may develop crossed eyes, seeking veterinary attention as soon as possible is essential. Doing so can help prevent further complications and treat the condition correctly.
Can you fix a cross-eyed Siamese cat?
Unfortunately, it is not possible to permanently fix a cross-eyed Siamese cat. This condition is caused by a neurological defect that affects the ocular muscles of the eyes, causing them to be misaligned and appear crossed. It is sometimes called strabismus when both eyes do not look in the same direction.
Sometimes, the condition can be improved through eye exercises or surgery. However, it is not possible to permanently correct the issue in cats. Because of this, the best way to manage the condition is to ensure your pet is comfortable and healthy overall by providing good nutrition, plenty of exercise, and regular veterinary checkups.
Additionally, you can work with your vet to help manage any discomfort or vision problems that may arise. It is also recommended to keep an eye on the cat’s eyes and ensure they do not worsen over time. Ultimately, while cross-eyed Siamese cats cannot be “fixed,” they can still live long, happy lives with reasonable care and lots of love.
How long do kittens stay cross-eyed?
Kittens are born with closed eyes, usually opening them within a few days of delivery. However, kittens may be born cross-eyed or develop crossed eyes after birth due to various causes.
Generally speaking, kittens who suffer from crossed eyes will remain that way until they reach the age of four months. At this point, the crossed eyes should correct themselves as the kittens’ vision improves.
If it doesn’t resolve independently, veterinary intervention may be necessary. Regular vet checkups are always recommended to ensure your kitten is healthy and happy!
If your kitten has crossed eyes, don’t worry too much; this is usually not a severe issue. However, if the crossed eyes don’t resolve independently by reaching four months of age, it’s best to consult your vet for further advice and treatment options.
Does Siamese have eye problems?
Siamese cats are known for their striking appearance and bright blue eyes but can also be prone to eye problems. Siamese cats have a genetic condition called inherited progressive retinal atrophy (PRA), which is an inherited form of blindness.
This condition causes the light-sensitive cells in the retina to degenerate over time, leading to gradual vision loss. Other eye problems that may affect Siamese cats include glaucoma and cataracts.
If caught early enough, these conditions can often be managed with medication or surgery. It’s essential to take your cat for regular checkups at the veterinarian so any potential eye issues can be detected and treated if necessary.
Keeping your cat’s eyes clean and debris-free can also help prevent any long-term eye problems. Regularly wiping the corners of your cat’s eyes with a warm cloth or using an eye wash will help keep their eyes healthy and clear. Siamese cats can enjoy a long, healthy life with proper care and attention.
