Is it bad to see a cat’s third eyelid?

Answered by Edward Huber

If you notice your cat’s third eyelid, it can be a cause for concern. As a cat owner, it’s important to be alert and observant when it comes to your furry friend’s health. The third eyelid, also known as the nictitating membrane, is a thin layer of tissue that helps protect and lubricate the eye. It normally stays hidden in the inner corner of the eye, but if it becomes visible, it could indicate an underlying issue.

Firstly, it’s essential to understand that seeing your cat’s third eyelid is not normal and may suggest an eye problem. There are several possible reasons why the third eyelid may be visible, and it’s crucial to have a veterinarian examine your cat to determine the cause and provide appropriate treatment.

One possible reason for the third eyelid being visible is an injury or trauma to the eye. Cats can get into scuffles with other animals, or they may accidentally scratch their eye while exploring their surroundings. These injuries can lead to inflammation and irritation, causing the third eyelid to become more prominent.

Another potential cause is an infection, such as conjunctivitis. Conjunctivitis, also known as pink eye, can cause redness, discharge, and swelling of the eye. When the eye is inflamed, the third eyelid may be pushed forward, making it visible.

In some cases, a more serious condition called cherry eye can be responsible for the third eyelid’s visibility. Cherry eye occurs when the gland that holds the third eyelid in place prolapses and becomes swollen and visible. This condition requires veterinary attention and may necessitate surgical correction.

Other possible causes include allergies, foreign bodies in the eye, or even systemic diseases that can affect the eyes. Only a veterinarian can properly diagnose the underlying cause of the visible third eyelid after a thorough examination.

So, what should you do if you see your cat’s third eyelid? The answer is simple: take your cat to the veterinarian for a comprehensive eye examination. While it may be tempting to wait and see if the issue resolves on its own, it’s always better to err on the side of caution when it comes to your pet’s health.

During the examination, the veterinarian will assess the eye for any signs of injury, infection, or other abnormalities. They may perform tests, such as an eye stain, to check for corneal ulcers or other damage. Depending on their findings, they may prescribe medication, recommend further testing, or refer you to a veterinary ophthalmologist for specialized care.

If you notice any part of your cat’s third eyelid, it’s important not to ignore it. The visible third eyelid may be an indication of an underlying eye issue that requires prompt veterinary attention. By seeking professional help, you can ensure that your cat receives the necessary treatment and care to maintain their eye health.
