I am popping out what Reven said about the chart that provided the proof. As it's a long list of charts and only chart midlist provided the proof, it's easy to miss. Thanks for analyzing them indivdiually Reven. I actually missed the proof when I first saw them.
Reven said about Cee's chart:
"This is where it gets interesting!
Grandpa Cosmic shows Bengal Tawny. We don't know what he hides, but it doesn't matter in this case.
Grandma Shazic shows Chateau Slate & White No. 1. As with grandma, the hidden fur is both unknown and not important.
Mum Abby shows Chateau Slate & White No. 1 from Shazic and hides Cosmic's shown or hidden fur.
Dad Rolfe shows Bengal Snow, and hides the same or a more recessive fur.
Kitten Rigby shows Bengal Tawny, which is known to be dominant to Bengal Snow.
His shown fur must therefore be Rolfe's hidden.
This chart proves that Chateau Slate & White No. 1 is dominant to Bengal Tawny."
