My cat's eye color is changing and he's acting strange. Is it FIV?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 12 lbs

My cats iris has been gradually changing colors and hes been acting weird the past couple days. Reading online it mentions a lot that it could be related to FIV. My 2 other cats came from a litter that had a kitten with FIV but they weren't tested. Our vet cleared him and said hes fine but we no longer have confidence in this vet and are scared something serious is happening to my cat. I've attached a picture of both eyes

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.
