Why Does the Third Eyelid Protrude?
There are multiple answers to the question, "Why does a cat's third eyelid protrude?" First of all, it is important to know that the protrusion of the third eyelid in cats is not a common occurrence. The circumstances under which the third eyelid becomes visible and for how long can make this symptom a matter to be taken seriously. If the third eyelid remains visible for more than a few hours, a veterinary examination is necessary. However, there is no need to worry immediately; sometimes the protrusion of the third eyelid is a perfectly normal biological manifestation.
Uyuklama ya da Rahatlama
It's normal for part of the third eyelid to be visible when the cat is very tired or relaxed. You may see your cat's third eyelid protruding while sleeping or immediately after a strenuous play session. The third eyelid will retract again after the cat wakes up and recovers.
Sedasyon ya da Anestezi
When a cat is sedated or anesthetized for a medical procedure, the third eyelid may cover part of the eye due to excessive physical relaxation. This effect may last for a few hours after waking from anesthesia but will disappear over time. The visibility of the third eyelid after anesthesia is considered normal. However, if it is still visible one day after the procedure, an examination may be necessary.

Conjunctivitis
The conjunctiva is the thin membrane that covers the inside of the eyelid and part of the sclera. Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva. Conjunctivitis occurs as a result of an infection, allergy, injury, or a foreign object causing discomfort in the eye. Conjunctivitis is not very common among third eyelid diseases in cats. Conjunctivitis in cats can be treated with eye drops or ointments containing antibiotics or steroids. As always, it is important that antibiotic use is provided in appropriate doses according to the recommendations of veterinarians.

Corneal Ulcers
The cornea is a transparent layer that covers the front of the eye in front of the iris and pupil. A corneal ulcer is a wound in the eye that causes pain and inflammation and can lead to the third eyelid being visible. Corneal ulcers occur as a result of scratching, scraping, or opening a wound on the eye. Some irritating and abrasive chemicals can also cause corneal ulcers. Corneal ulcers can suddenly develop into a very serious health problem. To prevent this from happening, it is necessary to go to a veterinarian as soon as it is noticed. Corneal ulcers can usually be treated with one or more eye medications. Uveitis The uvea is the central part of the eyeball and contains many blood vessels. Inflammation of the uvea is called uveitis. Uveitis usually causes the eye to appear red and be painful. Uveitis can sometimes also cause inflammation of the third eyelid. However, uveitis does not always cause this symptom. Cherry Eye There is a gland in the third eyelid that protrudes from the inner corner of the eye when it swells. This is called prolapse of the nittant membrane. It is commonly known as cherry eye. It is relatively uncommon among cats. Cherry eye is more common in Burmese cats. The only treatment for cherry eye is surgery.
