Why is my cat's left pupil suddenly looking way bigger than the right one tonight? Do I need to call the vet right away?

Tonight, I noticed that my cat's left pupil is significantly larger than the right one, and it seems to have happened quite suddenly. I'm pretty concerned because her eyes usually look normal, and I’m not sure what could have caused this change. Is this something that needs immediate attention from a vet, or is it okay to wait and see if it resolves on its own?

Answer

Your cat's sudden change in pupil size, with the left pupil being significantly larger than the right, is called anisocoria. It is important to observe this closely, as sudden eye changes can indicate underlying issues.

  • Anisocoria can be caused by several factors, including eye injury, nerve damage, or other health concerns.
  • Monitor your cat's behavior and look out for additional symptoms like squinting, redness, or discharge.
  • If you observe any accompanying symptoms or the condition persists, a vet visit is recommended.

A sudden change in your cat's pupil size can be alarming. Anisocoria could result from minor issues like stress or more serious conditions such as eye trauma or neurological issues. Keep an eye on your cat for any other signs like difficulty seeing, lethargy, or changes in behavior which could indicate a more serious problem that needs veterinary attention.

If you notice these signs or if the anisocoria doesn't resolve, it's best to have your cat examined by a veterinarian to determine the cause and necessary treatment.
