To Regina: >In Elfyr's post yesterday about Finnegan's unfortunate cat encounter >(happy for you that it wasn't worse!), Elfyr mentioned a third eyelid. >How many eyelids do ferrets have? Are the inner one(s) clear? Regina - ferrets only have two eyelids, unlike dogs and cats which have a third (also known as a nictitating membrane, which can also slide up and over the cornea - you may notice this in dogs and cats which are sleeping but which have their eyelids slightly open. -- Bruce Williams, DVM, DACVP Department of Veterinary Pathology [log in to unmask] Armed Forces Institute of Pathology [log in to unmask] Washington, D.C. 20306-6000 (202) 782-2600/2602 [Posted in FML issue 1195]
