Why can I see the inner eyelid on two of my cats but not the third one?

I've recently noticed that I can see the inner eyelid, or third eyelid, on two of my cats, but the third one's eyes look completely normal. This happened after they all took a nap together in their usual sunny spot by the window. Is this something I should be concerned about for the two with visible inner eyelids, or could it just be a natural variation?

Answer

Seeing the third eyelid on two of your cats could be a normal response to light exposure or sleep, but it's worth monitoring them for any other signs of discomfort or illness.

  • Third eyelids can occasionally become more visible after sleep or naps.
  • This is usually not a cause for concern unless accompanied by other symptoms.
  • If unsure or symptoms persist, it’s best to consult a vet.

The third eyelid, or nictitating membrane, can sometimes appear more prominent in cats, especially after they rest or when exposed to bright light. This is typically a normal physiological response. However, if you notice persistent visibility of the third eyelid, particularly with additional signs like lethargy, appetite changes, or discharge from the eyes, it might indicate an underlying health issue. Regular monitoring is advised to ensure no further symptoms develop.
