My cat’s pupils are different sizes, should I be concerned?

This evening I noticed that my cat’s pupils are not the same size when she was sitting on the windowsill. It's never happened before, and I'm wondering if it's something serious or just a temporary condition. Should I take her in to see a vet, or is there something I can look out for at home to ensure she's okay?

Answer

Unequal pupil size in cats, known as anisocoria, can indicate a variety of issues ranging from benign to serious. Monitoring your cat closely for other symptoms and changes in behavior is essential.

  • Monitor your cat for any changes in behavior or additional symptoms.
  • Consider if there have been any recent injuries or trauma to your cat.
  • Consult a vet if the condition persists or worsens.

Anisocoria can be caused by various factors, such as eye injury, neurological issues, or even infections. Sometimes, it may resolve on its own if caused by a minor irritation or change in lighting. However, if your cat exhibits any troubling symptoms like changes in vision or demeanor, seeking veterinary advice is advisable.
