Cool Female Rat

[JohnNJ]

First Siamese posted is without a doubt a ruby/red eyed Siamese, the other (rex) is a Pink eyed Siamese. I have both in my colony. I prefer the Ruby eyed Siamese.

I have a ruby eyed seal point siamese with very good coat and markings. What would I breed her to so that I would get a black eyed seal point siamese?

Thanks
