Hi All. DCat is going to the vets tomorrow with what I suspect is a melanoma of her iris based on my research.
Does anyone have any experience of a cat with one of these? Did anyone's cat have a dark spot in their eye and it not be a melanoma?
I stupidly googled last night whilst I couldn't sleep and now I'm convinced m going to lose my beautiful cat. 
You can see the spot quite clearly in this picture, she also has a dark smudge around the side.
