Has anyone ever experienced this before??? Our cat, Shachar, has started showing his third eyelid, and it's gotten progressively worse. Our vet is out due to the holidays, and I just wanted to know if anyone else has experienced this??? The only thing I can really find about it online is that it might be "hawes syndrome" which doesn't have any real cure, except to wait it out. Anyone have any ideas or information? Has this ever happened to any of your cats?
