Professor Charles Xavier:" Heterochromia was in reference to your eyes which I have to say are stunning. One green, one blue. It's a mutation. It's a very groovy mutation. I've got news for you, Snowball. You are a mutant."

The pure, almost albino white, is very cool as well.
This is one my family's cat(used to live). She gets white fur everywhere, a little bit fat i'd say, has 2 different colored eyes, weird personality, friendly and cooky.
