It is common for kittens to undergo an eye color change. If your cat is an older cat though, it may signify infection or more serious underlying disease. Any sudden change in eye color should be addressed by your vet or veterinary ophthalmologist.

This can be normal, and if the color changed started when she was four months old, that's the right time for it to happen. If there are no other symptoms and she is acting perfectly normal, I would not be worried.

There is not a photo attached to this post. I recommend to get a second opinion with another veterinarian. The iris can change due to a few conditions including freckling, FIV and iris melanoma (a type of cancer). A physical exam is needed to look at the iris. Testing for FIV is generally straight forward and involves a simple blood draw and can generally be done during the same visit. It's best to get this checked out sooner rather than later. so try to get this done within the next couple days. I hope this helps. Please feel free to post any additional questions.

I think it depends on the lighting and how dilated her pupils are at the time. Totally normal! The iris has many different color filaments in it and depending on the shape and amount of light hitting them, they may appear a different shade.
