Why is my cat's eye developing new brown spots? Is it serious?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 2 years and 9 months old | 10 lbs

My cat has always had a small amount of brown around the outside of her yellow-green eyes, but recently there appears to be a lot more brown in one of her eyes than before, and it is in an odd, random pattern. Is this something serious? Is there anything that we should do?

That change could be due to an injury. Her eyes look clear and normal but I would bring her in for an exam next week to double check. Changes in the eye pigment can be caused also by infection or cancer. They will look into the eye and may recommend a blood panel and blood pressure check. Hopefully it is nothing to be concerned about. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Cissy.
