My little Evie keeps showing her third eyelids, mainly when her eyes are half open. She had conjunctivitis a month ago now, so maybe it's this returning? She is trying to close her left eye as much as possible. I'm so worried about her, we can get her to a vet first thing. We've still got some Futhicalmic eye drops, which I'll use in the mean time. What could it be? I'm trying to mentally prepare that it could be an infection, as she has been quite ill.
