One of my cat's pupils just got way bigger than the other, is that bad?

Just this evening I noticed that one of my cat's pupils is significantly larger than the other. She hasn't had any accidents that I know of, and she seems otherwise normal. I'm really concerned because I’ve never seen this happen before. Could this be a sign of something serious, or is it sometimes just a temporary issue?

Answer

Your concern about your cat's unequal pupils, also known as anisocoria, is understandable. While sometimes it might not be serious, this condition can indicate underlying issues that need veterinary attention.

  • Anisocoria refers to a condition where one pupil is larger than the other.
  • It can occur in cats due to various reasons including injuries, infections, or other health problems.
  • A prompt veterinary evaluation is advisable to determine the cause and appropriate action.

Uneven pupil sizes in cats can be caused by different factors, ranging from mild to more serious conditions such as trauma, neurological disorders, or eye diseases. If your cat is behaving normally, it may not be an immediate emergency, but it is important to have a veterinarian examine her to rule out any potential problems.
