A few weeks back, I noticed my cat's left eye's iris is discoloring from the corner (brownish red, iris is gold color). She is 8 years old, female. She has no other complaint whatsoever.
I know I should check with professional, which I did. I took her to the vet. The doc checked how the eye reacts to light and movement, and everything seemed fine according to him. He did not do anything further. Somehow, I felt he was not very confident or sure. He told me to wait and see if the condition progresses. It's been a couple of weeks now. I can't really judge if the discoloring is progressing. However, it definitely did not improve.
Do you know what this discoloring is?
Should I seek another vet's opinion, or am too paranoid?
