Why Are My Cat’s Eyes Always Dilated?
If you’ve noticed that your cat’s eyes are constantly dilated, you may be wondering why this is happening. While it’s normal for a cat’s eyes to dilate in certain situations, such as low light or when they’re excited, persistent dilation can be a cause for concern. Here are some possible reasons for your cat’s dilated eyes:
1. Low Light Conditions: Cats have excellent night vision due to a structure called the tapetum lucidum, which reflects light back through the retina. Therefore, in dimly lit environments, their pupils may naturally dilate to allow more light in.
2. Excitement or Fear: Cats may also have dilated pupils when they’re feeling excited or fearful. This response is part of their fight-or-flight instinct, preparing them for potential danger or intense play.
3. Stress or Anxiety: Chronic stress or anxiety can cause a cat’s pupils to remain dilated. If your cat is constantly in a high-stress environment, it’s important to identify and address the underlying causes to improve their overall well-being.
4. Medications: Certain medications, such as eye drops or systemic drugs, can cause dilation as a side effect. If you recently started your cat on any medication, consult with your veterinarian to see if this is a possible cause.
5. Eye Problems: Various eye conditions and diseases can lead to persistent dilation in cats. These may include glaucoma, uveitis, or trauma to the eye. If you suspect your cat has an eye issue, such as redness, discharge, or cloudiness, consult a veterinarian for a thorough examination.
6. Neurological Disorders: In some cases, neurological disorders like Horner’s syndrome or brain tumors can cause a cat’s pupils to remain dilated. Other symptoms, such as facial paralysis or difficulty walking, may accompany these conditions.
7. Age and Breed: Older cats or certain breeds, such as Siamese or Burmese, may naturally have more dilated pupils. If your cat has always had dilated eyes and has no other concerning symptoms, it may simply be a normal variation for them.
