It started with smaller dots and black areas in her eye ~2 years ago:

Since then we took her to the doctor many times to make sure she is okay. He told us that its all right, simply she has more pigments in here eyes, and its okay as long as there are no fluids.
Over time a lot of black areas started appearing in her eyes, and I started nagging the doctor. He still said that its just pigments, but if we wanted to be sure, we should take her to a detailed eye examination.
When we noticed that her pupils got deformed, and didn't respond to light like her healthy one we immediatelly took her to an eye examination, and they told us she has a high possibility for diffuse iris melanoma, which can spread to parts of her belly and lungs. They also told us, there is a chance that there is nothing wrong, but there is no way to make sure. They can try to get some fluids from her eye, but that doesn't give an accurate representation.
We decided to have her eye removed, because we think its better to have 0 chance for diffuse iris melanoma and it spreading than anything more than 0. Especially in this case where its very likely. As far as I understood even if we knew this sooner there weren't anything we could do.
This was a very hard decision for us, having such a radical surgery on our first cat feels depressing, and the chance that we do this for nothing makes things even harder. We saw on the internet that one eyed cats gets used to the new situation quickly, but that doesn't fully reassure us.
I'd like to ask you to share your experience with cats you know that had diffuse iris melanoma, or one eyed kittens. We would like to make sure she feels loved and can live a full life after this. Thanks in advance! Make sure you check your cats health regularly.



cats with one eye do great. they might have trouble judging jumps for a while and will obviously not be able to see well on the areas the other eye would have seen that her remaining can’t, but their bodies are covered in whiskers and you would be surprised how well they get around. i work in vet med and have seen dozens of these guys. literally the only difference with them is that they have altered depth perception and a blind spot. cats adapt very well.
