Cats have an inner or third eyelid humans don’t have. Our inner eyelid isn’t always visible, but it tends to keep our eyes protected and moist. It can wipe away debris. It helps when we need to stalk prey through grass so our eyes don’t get harmed. Vets once thought this third eyelid had no purpose and wanted it out of the way so they could exam our eyes.
Good thing there are humans smart enough to know our inner eyelid has a purpose and they need to let us have it.
