The inner eyelid of my cat is covering half of its eye all of a sudden, should I worry about this or will it clear up by itself?

Earlier today, I noticed that the inner eyelid of my cat is covering about half of her eye, which just suddenly appeared out of nowhere. She doesn’t seem to be in pain, but it looks quite unsettling and I’m not sure if it’s affecting her vision. Is this something that might resolve on its own, or is it a sign of something more serious that needs immediate attention?

Answer

The sudden appearance of your cat's inner eyelid covering part of her eye can be concerning, but it's often not an emergency. While it may not cause immediate pain, it can sometimes indicate underlying health issues.

  • Appears though your cat is not in pain.
  • Could resolve on its own, but monitoring is important.
  • Might be a sign of an underlying health condition.

The third eyelid, or nictitating membrane, can cover part of a cat's eye for several reasons, such as irritation, minor trauma, or a response to illness. Although this might not immediately affect her vision or cause discomfort, it's important to observe any changes in her behavior or appearance over the next few days. Gentle reassurance is key, but if her condition persists or if she starts showing other symptoms like lethargy or appetite changes, a veterinary check-up is recommended.
