My cats have this film covering a 1/4 of their eye in the lower corner. I`ve been told this is normal but when it doesn`t go away it`s a sign the cats is sick. Is this true? They seem to be acting normal and don`t seem sick. Thank you for any help or advice you can give me.
This could be the third eyelid. If they are up it could mean the cat is sick, vetcare
