I noticed my cat's third eyelid is showing and her eyes are partially closed, should I be freaking out about this?

This morning, I noticed that my cat's third eyelid is partially covering her eyes, and her eyes seem to be more closed than usual. She seems a bit more lethargic, and I’ve read that this could be a sign of illness. Is this something I should be freaking out about, or is it common and not a big deal?

Answer

Your cat's third eyelid appearing and increased lethargy can be signs of underlying health issues, warranting some concern and monitoring.

  • Partial coverage of the eyes by the third eyelid can signal illness.
  • Lethargy may indicate discomfort or weakness.
  • Observing other changes in behavior or appetite is crucial.

The third eyelid, or nictitating membrane, in cats sometimes becomes visible due to conditions like conjunctivitis, dehydration, or systemic illnesses. While it can occasionally be harmless, it's important to monitor your cat's overall behavior and contact a vet if you notice persistent symptoms or additional issues. Cats tend to hide discomfort well, so increased lethargy is worth discussing with a professional.
