You can't get kitties in certain colors. Ever notice that?
Like you never see a gray and orange cat, or a chocolate and cream cat. So why can they come up with those wild 3-color combos, like you saw on my cat Baci (the Christmas photo)?
Why aren't 3-color male kitties worth anything to a breeder? Did you know there was such a thing as a torbie? Which chromosome is the only one that can carry the gene for red (= orange) fur?
Barbara French explains it all for you.
