Hi, Fabao asked me to post my proof also, I was fortunate enough to get the fur, although my starter also blessed me with fire eyes ha ha
This is Cara Scarecrow starter and her 9 babies so far (number 9 is another gen diamond which is too far down to see). Paired Cara the starter with a siamese tortie and got Bubbles, a siamese tortie. Then put Cara with an Aby Dark Chocolate and got Aby Dark Chocolate back.
Then tried to make a boy hiding unknown fur so I could breed back to the starter, and failed miserably. However I put Bubbles the siamese tortie hiding fur X from Cara with an aby dark chocolate Dark Magic, and got Hogan an aby dark boy that I knew was hiding fur X from Cara/Bubbles. Put grandson Hogan aby dark with starter Cara and got Josiah the Aussie blue mist.
p.s. the unknown fur X from Cara could have also turned out to be Abyssinian Dark Chocolate and not Aussie Blue Mist. fortunately that was not the case (this time!)
