It is dad's hidden
So the snowshoe Bluepoint must have hid the shown of your new born.
So the Russians passed their hidden instead of their shown fur.
One of them hid Snowshoe Bluepoint and the other Abyssinian - Black Silver.
Russians can't hide behind Blue Point as Russians are more dominant.
We never know what kitties hide that is all I can say.
Unless we know our kitties very well ...
