My rudimentary understanding is this. My Silver Tabby has one Silver Tabby parent and one Foxie S&P. She obviously inherited her dominant parent, but the other parent should have passed her displayed breed/coat: the Foxie S&P. Same thing with the Chateau. Is there any possibility that either of them would have inherited anything other than the Foxie as her Recessive? Both cat's grandparents on their recessive side are all Foxies as well, so the likely hood of any surprises is less... if that even matters.
Now, of course, I can't mate two girls together. I'm going to have to find a boy with the same mash up, or even a boy Foxie S&P to gain anything... maybe I'll do that.
You can never have too many cats, right?
