Their eye anatomy is different, and their eyes glow resulting from a reflective membrane behind their eyes that helps them see well at the hours of darkness. They’ve two eyelids (one above the attention and one below) like we do, but in addition they have what’s known as a 3rd eyelid, or nictitating membrane.
We don’t often see a cat’s third eyelid unless they are only waking up from an extended nap or are otherwise looking around lazily. Then, you may give you the chance to glimpse their third eyelid before it slides back into place. Nevertheless, certain problems and conditions outside of those normal circumstances can lead to its sustained appearance, like if the cat is dehydrated or injured.

Many other systemic diseases may cause dehydration in cats, so an examination together with your veterinarian is warranted.
For an older cat, generalized weight reduction may cause the fat pad behind the attention to cut back in size, causing the attention to sink inwards and the third eyelid to lift up in turn. Veterinarian guidance and care are crucial to evaluate the reason behind the load loss and third eyelid exposure.
3. Nerve Damage
When a cat suffers from nerve damage, it could possibly cause one or each third eyelids to at the least partially prolapse. Damage to the facial nerve, either from infection, inflammation or neoplasia (growths) may cause the dysfunction of the third eyelid. If a 3rd eyelid showing is resulting from nerve damage, other signs of nerve damage are more likely to appear, including pupil size changes and lack of facial muscle movement.
