My cat's pupils look weird; one eye is normal, the other won’t dilate at all. Is this something a vet needs to see right away?

This afternoon, I noticed that my cat's pupils look different from each other. While one eye's pupil seems to adjust normally, the other stays very small and doesn't seem to dilate at all. I'm worried if this is something that could be serious. Should I take her to the vet immediately?

Answer

It sounds like your cat is experiencing anisocoria, which is when one pupil is a different size than the other. This could be a sign of an underlying issue that needs attention.

  • Monitor your cat's behavior and health closely.
  • Anisocoria can have several causes, some of which may require urgent attention.
  • If in doubt, consult a veterinarian to ensure your cat receives appropriate care.

When a cat exhibits uneven pupil sizes, it could be due to a range of causes, including eye injury, neurological conditions, or other health issues. It's important to have a vet assess the situation to determine the cause and necessary treatment. While it may not always indicate something serious, it's always better to err on the side of caution when it comes to your pet's health and well-being.
