I have three cats, about 4wks ago 1 of my cats ozbournes third eyelid was halfway covering his eye i took him to the vet for flea treatment and mentioned this to them, they said he,s just probably feeling under the weather abit but this wk my other 2 cats have started with the same look with their eyes. Their eyes arn,t weeping and they are not sneezing altho they are not eating as much as usual and do look very sorry for themselves. When my cats are outside you cant see their third eyelid (as usual) can anyone pleeeeease give me any information before i take them to the vets ? ps i havent introduced anything new into my household i.e airfresheners.
