I have a 20 year old kitty that is allergic to everything according to her allergy test. Between Jan and May the allergy shots she’s on do not work well. I’m giving her nose drops per vet advice to help. This year is the first time her third eyelid refuses to retract in one eye. It’s kind of blood shot and the vet did not seem to concerned about it but it’s covering 1/2 of the eye and bothers me. Does anyone have any advice on trying to get it to retract? It bothers me probably more that it bothers her. I’ve been putting liquid tears in to keep it moist but it’s not retracting.
