How many eyelids does a cat have on each eye?

Cats have three eyelids on each eye, which is why the choice indicating three is the correct answer. The three eyelids consist of the upper eyelid and lower eyelid, which function similarly to those in humans. The third eyelid, known as the nictitating membrane, is a thin, translucent eyelid that helps protect the eye and keep it moist. This additional eyelid allows cats to have better vision during hunting and helps shield their eyes from debris and injury. The presence of three eyelids is a unique adaptation that enhances their overall eye health and functionality compared to those animals that have only one or two eyelids.
