Third eyelid

Hello[emoji]128522[/emoji]
Question for anyone with experience with a cat whose third eyelid is showing.

My darling peaches has had this issue for a while now. At first I thought it was just because she was dehydrated when she first came to us. It's not always showing so it puzzles me.
We took her to the vet and she is perfectly healthy otherwise. Weight is good, no infections, she just got her second dose of dewormer. The only thing the vet suggested is L-lysine(sp?) added to her food. She said it may help, but because it comes and goes(mostly seen after she's had hers eyes shut) that it might just be slow reflexes?

Anyone encounter this issue with their cat?

She was just sleeping so this is what it looks like right when she opens her eyes. It does eventually go down after she's been awake awhile.

The key with this is ruling out illnesses.

Kitty may have an overall appearance of good health, but until a full blood panel is done, to look at all organ and system functions, you really won't know.

From the picture, and it's hard to get a good look at her eyes, but to me, unless this pic was taken in the first 5 seconds of waking from a deep nap, there may be something out of sorts inside.

That being said, it is normal when a cat first wakes to see their inner lids, but just for seconds until they are fully retracted.

I always say, the eyes are the windows to the cats inner works, and can tell alot.

Second to behavior and appetite or lack of. Interest in being social or more of a hidey napper, etc.
