This is a first for me. We always had barn cats, strays, etc. But we have four kitten that are maybe three months old now. Three of the kittens eyes changed to green, but one black and white kitten eyes stayed blue! I have never seen this before. The only blue eyed kittens we have ever had is one that I have in the house, for eight years now, she looks like a siamese, and we have had a few kittens that were pure white with the dark markings like a siamese and their eyes stayed blue. But this black and white one is a first and is a nice surprise.
