Why Are My Cat’s Eyes Always Dilated?

If you’ve noticed that your cat’s eyes are always dilated, you may be wondering why this is happening. While dilated pupils can be a normal response to certain situations, persistent dilation may indicate an underlying health issue. In this article, we’ll explore some common reasons why your cat’s eyes may be dilated and address some frequently asked questions about this behavior.

Causes of Dilated Pupils in Cats:

1. Low Light Conditions: Cats have excellent night vision, and their pupils dilate in low light to allow more light to enter the eyes. This adaptive trait helps them see better in dark environments.

2. Excitement or Fear: Cats may have dilated pupils when they are excited or frightened. This response is part of their “fight or flight” instinct, preparing them for potential threats or opportunities.

3. Pain or Discomfort: Cats in pain may exhibit dilated pupils. If your cat’s eyes are always dilated and they’re displaying other signs of discomfort, such as decreased appetite or lethargy, it’s essential to seek veterinary attention.

4. Medications or Drugs: Certain medications or drugs can cause pupil dilation in cats. If you’re administering any medications to your cat, consult with your veterinarian to determine if this could be the cause.

5. Eye Injuries or Inflammation: Trauma or inflammation in the eyes can lead to dilated pupils. If your cat has recently experienced an injury or their eyes appear red and irritated, it’s crucial to have them examined by a veterinarian.

8. Systemic Illness: Various systemic illnesses, such as kidney disease or high blood pressure, can lead to dilated pupils in cats. These conditions often have other accompanying symptoms, so it’s essential to consult with a veterinarian for a proper diagnosis.
