Black spots in my cat's eye

[mycatchuck]

I have a 6 year old male cat, I love him with every piece of my heart and sole and would have a melt down if anything should ever happen to him, his names chuck! Any who, not so much recently but like maybe a year or two ago me and my dad noticed black spots in the yellow of his eye, they change shapes, they grow more appear. They don't bother him that is obvious but is it a form of melanoma? Also his eye has never been swollen or irritated, no excessive mucous discharge, no red no anything he just has one big black spot below his pupil and maybe like two very very small ones. The big one seems to be getting bigger from when it evolved, Hopefully someone can help i mean I'd rather look at the spots then have his eye removed they don't bother me I really just want to know what they are.Thanks for any help given! Also here's the link to cat's community to view the picture, Please let me know what you think veterinarians and fellow cat lovers that may have had the same problem. Once again I do understand ocular melanoma but there's not other symptoms other then the spots, he eats, plays, drinks water, tortures me in my sleep....and he's had the black spots in his eye for awhile. Thank You for any in site given on this situation...    http://www.medhelp.org/posts/Cats/Black-spots-in-my-cats-eye/show/1024201?post_id=post_4760950

I agree with Dr. Humphries that most of the time this is normal pigmentation of the iris and not a concern.  It sounds like you said they are growing and changing so this could be a concern.  You should have your veterinarian examine him closely.  He/she may even refer you to an animal ophthalmologist.  That is what I usually do with any that look suspicious to me.  

You can have melanoma in the eye without any other symptoms.  It can spread, so if it is likely melanoma, it is better to have the eye removed before it spreads.  They do great with the surgery and afterwards adapt very well.

Good luck,

I wish that picture was close enough to his eye for us to see.  

Just guessing I would think you are seeing normal pigmentation of the iris.  This is rather common.  I cannot say for sure, but most likely not a melanoma.  This is especially true when you consider you have watched this for a couple of years now and it has not grown.  

  At 6 years it is time for a good physical exam anyway, have your veterinarian look closely at those spots.
