Why are my Siamese kitten's third eyelids always showing? Normal?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Male | neutered | 4 months and 27 days old | 7 lbs

Hi, I have a Siamese kitten who is about 5 months old and his third eyelids show at all times, he is otherwise completely normal. I took him to the vet today and they said he was fine and that this can happen. I just wanted to be sure I'm not dropping the ball trusting the vets advice.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Leroy. Oh my, he is adorable! He has the cutest cross eyes. Typically the third eyelid should not be out all the time, and it can be a sign of a problem. Now if the vet examined him and said he was fine, then it may be normal for him due to the shape of his eyes. It could also be a sign of intestinal worms, so make sure he is up to date on his deworming treatments. Please give him a cuddle from me, he is beyond cute!

My cat shows a third eyelid. As you can tell, it only protrudes more when relaxed. Overall he is healthy. No worms, all shots, and very healthy. Since I got him, his one eye slightly waters but cleaning it relieves it for hours. So it may be because
Thanks for using Boop by Petco! Winston is a cutie and I am not concerned about this. I actually see this in many relaxed cats. Unless the watering is lasting more than a day, there is full-on squinting or rapid blinking, redness, cloudiness, or other worrisome signs, I am inclined to ignore it. If you have any concerns, definitely see your vet to make sure everything looks normal. Best of luck to you and Winston!

My cats eyes have changed, the white from the corners seems to be larger and he looks unwell.
Hello and thank you for contacting Boop by Petco. The white tissue in the corner of the eyes is the third eye lid. It goes up like this when a cat is unwell. It is not a specific sign for one particular disease but it often means that a cat has fever, has breathing problems, has abdominal discomfort, muscle or joint pain. Please, take Lancelot to your local vets tomorrow for full clinical examination. Your vet may recommend a blood test or abdominal scan to find out what is going on. Good luck !

My new kittens third eyelids are showing? Shes generally well, eating, drinking, playing, pooping.
Hi and thanks for using Boop by Petco! Sorry to see that Scarlett is having problems. This can indicate a few things such as something called Horner's Syndrome, Haws Syndrome, or some type of injury to the eye or eyelids. It's not likely Horner's because that is usually one eye and is a neurological disorder of the eye and facial muscles. Haw's syndrome is more likely since it's both eyes. This is an odd syndrome of elevated third eyelids and often times diarrhea. Some people suspect tapeworm infestation or a viral cause for this syndrome. It's usually not treated and is most times self limiting and will resolve. Eye and eyelid injuries are often again only one eye but could less commonly be both eyes. If you don't notice any discharge, rubbing of the eyes, redness of the eyes, or pain I would just advise monitoring the situation. I did notice that her left third eyelid and eye looked redder than the right which could mean that she does have something going on with that eye, such as

Should my cat’s third eyelid be this color?
The third eyelid does look a bit darker than normal, and they are protruding a bit, which can indicate a problem like intestinal worms. I'd have Leef checked out by a vet for this, and bring in a sample of his poop for the vet to examine for worms. If he does have worms, the vet can treat him. Give his vet a call to make him an appointment. I hope this helps.

for about a week i’ve been noticing Mr. C’s third eyelids of both eyes are out when they arent supposed to be. they seems to retract occasionally but for the most part they’re just always out. otherwise he seems perfectly fine, he’s eating and playi
Thank you for submitting your question regarding Mr. C. Other than his third eyelids being elevated, the eyes appear normal in the picture. His pupils are a normal and equal size. I do not see any redness in the eyes or discharge present. It sounds like he is acting well at home. If his attitude or appetite changes or if he begins squinting or pawing at the eyes, then I would be concerned. In this case, he will need to see his veterinarian again. Otherwise, it should be fine to monitor him at home. I hope this information helps!

Good evening We got a new kitten 2 weeks ago and a few days ago we noticed that his third eyelid is showing....this only seems to happen at night and it comes and goes depending on how much he is playing....during the day he is extremely playful an
This can be a sign of sickness or an infection in cats. however, since he is normal in the day,he may be tired at night and the eyelid comes out. If there is no squinting or ocular discharge, and no sneezing, then i would not worry at this point. Monitor his activity level and eating habits and if any changes are noted, then i would get him checked

We adopted a female cat about 7-9 months, she's neutered and got her vaccine which should be done again next year. A friend gave her to us who found her outside and fostered her and took her to vet. The doctor said she's healthy but what concerns me
Hello. When the third eyelids are prominent, then this could be an indication that a cat is unwell, but from your picture, Nojiko looks perfectly healthy, bright & alert. Just a corner of the third eyelids are visible, which can be perfectly normal in many cats. Any concerns, you should contact your veterinarian for a much more thorough examination. Thanks for contacting Boop by Petco.

Why does my cats 3rd eyelids always show like this?
In cats it'a usually due to an intestinal problem, worm infestation can also cause that. the first step would be to deworm him with a high quality dewromer such as Drontal or Profender, if it does not solve the problem you will need to take him to the vet for a checkup and probably other tests such as ultrasound and blood test.

my cat's eyes seems weird. it won't open fully on the inside
Having the third eyelid up is often a sign of a systemic disease from a virus or infection, not an eye problem itself. This can also be caused by intestinal parasites. I recommend a veterinary exam and testing of his blood for feline leukemia and aids and a fecal test for intestinal parasites. They will also check him for anemia and make sure his organs are functioning properly. Once they find the reason then they can prescribe the correct treatment.

So her third eyelid is showing, and that can be a sign of intestinal parasites in cats. I would take her into the vet. The vet can diagnose what is causing her third eyelids to show, and can treat her. Best of luck.
