My cat’s pupils are staying huge and not changing with light, should I be worried or is this normal?

Earlier today, I noticed that my cat’s pupils are staying really large and don't seem to be adjusting to changes in light. It seems unusual because they usually contract in bright environments. Should I be worried about this, or is it something that can happen from time to time with cats?

Answer

It is concerning that your cat’s pupils are staying large and are not responsive to light changes as they usually do. This unusual behavior in your cat's eyes could indicate an underlying issue that requires attention.

  • Unresponsive pupils can be a sign of a serious condition.
  • It’s important to monitor any other unusual behaviors or symptoms.
  • Consult a vet to ensure your cat’s well-being.

Your cat's pupils usually change size in response to light: large in dim environments and smaller in bright light. Persistent large pupils that don’t adjust could signal conditions such as hypertension, retinal disorders, or neurological issues. While it may occasionally happen without cause for alarm, ongoing or sudden pupil dilation should be evaluated by a veterinarian to rule out serious health concerns.
