From my testing so far Purple kiwi is recessive to Aby Salt & Pepper & Dom to Bengal Blue
To further elaborate on my post the toyger tan was an accidental breed but it did give some good insight because I have proven kiwi recessive to aby salt and pepper. Since the starters fur was pulled and the kiwi cannot possibly be hiding moms shown fur of toyger tan it must be hiding moms hidden fur of either the burmilla choc silver shaded or bengal blue from way back in the line.
