My cat's got one pupil way bigger than the other, is this a big deal?

This morning I noticed that my cat's pupils looked different — one is significantly larger than the other. It took me by surprise because this hasn’t happened before. I’m concerned about what could be causing this, and whether I need to have her checked by a vet immediately. Could this be something serious, or is it possibly just a temporary thing?

Answer

Your cat has developed anisocoria, a condition where the pupils are of unequal size. While this can be caused by several factors, it's important to investigate the underlying cause promptly.

  • Schedule an appointment with a veterinarian as soon as possible.
  • Monitor for any additional symptoms like vomiting, lethargy, or loss of appetite.
  • Keep your cat calm and comfortable until you consult with a vet.

Anisocoria can be due to issues ranging from minor to serious, such as trauma, exposure to toxins, or neurological disorders. It's crucial to have a vet examine your cat to determine the cause and appropriate treatment. Although the situation might resolve on its own, a vet consultation will ensure that any potential issues are addressed promptly.
