Why is my cat's third eyelid showing? Is the vet's medicine right?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Mediumhair | Female | spayed | 7.7 lbs

Took our cat to the vet since her third eyelid was covering half her eye since last one week even when she is active. Her appetite has decreased slightly but she is active otherwise. The vet has prescribed eye drops TOBA DM to be put thrice a day. Is it the right medicine? Is it a life threatening disease? will it affect her vision? How long will it take for her to recover fully? Please advice.

Your vet prescribed a general antibiotic eye drop which also contain steroids, from my experience when both third eyelids go up into the eye like this, it is usually not an eye related disease, it's more likely to be an intestinal disease. if she has not been dewormed lately, i would recommend starting by deworming her, often it is the discomfort related to the worms in the intestines that is causing this symptom. once the abdominal discomfort will be over, this symptom will disappear.
