Sable Panda Ferret or Silver Mitt Ferret Wanted!?

Hi, I am after a female Sable Panda Ferret, or Silver Mitt Ferret, kit preferred. If somebody has one for sale, or knows somebody could you let me know please? I am having a lot of trouble finding one. I currently have a Red Eyed White male, Sable female, and SAFA Mitt Sable male. She would be going to a loving home, with regular attention, and 2 storey playhouse. Thanks!
