Thank you for all your help everyone.
I will defiantly show the vet a couple of photos of Picasso's eye, but it will have to wait a bit. We are bringing Picasso in for his booster shots I think it was, in about 2 weeks. I'll ask the vet then.
He's had this brown spot in his eye ever since we got him, and he's about a year old now, so waiting 2 more weeks to see what it is probably wont hurt.
I'll make another post after we find out, since you guys all seem to care so much! ♥ ♪
