Why are my cat’s eyes suddenly two different colors? This intriguing phenomenon, known as heterochromia, can occur due to genetics, injury, or health issues. Understanding the underlying causes can help determine if veterinary attention is necessary.
What Causes Heterochromia in Cats?
Genetic Factors and Breeds Prone to Heterochromia
Heterochromia is often genetic, especially in certain cat breeds. Breeds like the Turkish Van, Turkish Angora, and Japanese Bobtail are more likely to have cats with different colored eyes. This occurs when there’s an uneven distribution of melanin, the pigment responsible for eye color, during development.
Injury or Trauma
In some cases, a sudden change in eye color can be due to an injury or trauma to the eye. This might cause inflammation or bleeding, altering the appearance of the eye. If your cat has recently had an accident or shows signs of discomfort, consult a veterinarian to rule out any serious issues.
Health Issues and Diseases
Certain health conditions can lead to heterochromia or changes in eye color, such as:
- Uveitis: Inflammation of the uveal tract can cause color changes and requires immediate attention.
- Glaucoma: Increased pressure inside the eye can lead to color changes and vision problems.
- Cataracts: These can cause a cloudy appearance, altering the perceived color of the eye.
Medications and Treatments
Occasionally, medications or treatments for other health issues can affect eye color. If your cat is on medication and you notice a change, discuss this with your veterinarian.
How to Identify and Monitor Changes in Eye Color
Regular Observations
Keep an eye on your cat’s behavior and physical changes. Regularly check their eyes for any signs of:
- Redness or swelling
- Discharge or tearing
- Changes in pupil size or shape
When to Seek Veterinary Advice
If you notice any sudden changes in your cat’s eye color, especially if accompanied by other symptoms like lethargy or appetite loss, it’s best to consult a veterinarian. Early diagnosis can prevent potential complications.

Conclusion
In summary, if your cat’s eyes suddenly change color, it’s crucial to consider both genetic and health-related causes.
