Why is my cat's third eyelid swollen and protruding after rough play?

Updated On September 23rd, 2025

Pet's info: Cat | Norwegian Forest Cat | Male | neutered | 8.6 lbs

My cat ran away from the house in January and when he came back the eye seemed to have been cut open slight on the outer edge, but the vet said it will heal. The third eyelid has always been showing since, but it was never swollen. We recently adopted a new kitten and they play with each other very rough. Today I saw that his eyelid was protruding and is swollen. I don’t know what is going on and if it might be from the kitten accidentally scratching the eyelid that was already showing.

Thank you for submitting your question regarding Hazel. In this picture, both third eyelids look to be in their correct positions. The conjuctiva (lining to eyelid) of the left lower lid is very swollen. It is possible that the kitten scratched his eye while they were playing. He may also have an eye infection. He will likely need to see his veterinarian for a closer evaluation and medication. In the meantime, do not allow him to scratch the eye. I hope this information helps you and Hazel!
