In this article, we’ll explore the possible reasons behind dilated eyes in cats and what you can do to address the issue.
Understanding Dilated Eyes in Cats
Dilated eyes, also known as mydriasis, occur when the pupils become larger than normal, allowing more light to enter the eye. In cats, dilated eyes can be a normal response to certain stimuli, such as darkness or excitement. However, persistent or uneven dilation can be a sign of an underlying medical issue that requires attention.

Why Is One of My Cat’s Eyes Dilated?
As a responsible and caring cat owner, it’s natural to be concerned when you notice any unusual changes in your cat’s behavior or physical appearance. One common issue that can cause worry is when one of your cat’s eyes appears dilated. In this article, we’ll explore the possible reasons behind this phenomenon and what you can do to help your feline friend.
What Does a Dilated Eye Look Like?
A dilated eye, also known as mydriasis, is characterized by an abnormally large pupil. Normally, a cat’s pupil should be around 1-2 mm in diameter. When an eye is dilated, the pupil can become as large as 4-6 mm or even more. This can give the appearance of a “staring” or “glassy” eye. (See Also: How Old Can Male Cats Reproduce)
Possible Causes of a Dilated Eye in Cats
There are several reasons why one of your cat’s eyes may appear dilated. Some of the most common causes include:
- Light Sensitivity: Cats have a natural response to light, and their pupils will dilate in low-light conditions to allow more light to enter the eye. However, if your cat’s eye remains dilated even in bright light, it could be a sign of an underlying issue.
- Pain or Discomfort: Cats may exhibit dilated eyes as a response to pain or discomfort, particularly in the eye or surrounding area. This could be due to conditions such as conjunctivitis, uveitis, or corneal ulcers.
- Fear or Anxiety: Cats can become stressed or anxious in response to changes in their environment, leading to dilated eyes. This could be caused by changes in your work schedule, moving to a new home, or introducing new pets or people into the household.
- Neurological Disorders: Certain neurological conditions, such as epilepsy, can cause dilated eyes in cats. Other signs of neurological disorders may include seizures, tremors, or changes in appetite or behavior.
- Infections: Bacterial or viral infections, such as feline immunodeficiency virus (FIV) or feline leukemia virus (FeLV), can cause dilated eyes in cats.
- Trauma: Head trauma or injuries to the eye can cause dilated eyes in cats.
- Systemic Diseases: Certain systemic diseases, such as hyperthyroidism or diabetes, can cause dilated eyes in cats.
- Medications: Certain medications, such as anesthetics or sedatives, can cause dilated eyes in cats as a side effect.
Other Signs to Look Out For
In addition to a dilated eye, there may be other signs that indicate an underlying issue. Keep an eye out for:
- Redness or Discharge: Redness, discharge, or crusting around the eye can be a sign of infection or inflammation.
- Squinting or Avoiding Light: If your cat is squinting or avoiding light, it could be a sign of pain or discomfort in the eye.
- Changes in Appetite or Behavior: Changes in appetite, behavior, or overall demeanor can be indicative of an underlying issue.
- Vocalization or Whining: If your cat is vocalizing or whining more than usual, it could be a sign of pain or discomfort.
