Ok so to clarify Violets above post.
In the Tawny Tabby proof Sadie the Cream & White Tabby was previously shown to hide Scottish Blue & White
Sadie bred to a Tawny Tabby and the baby was a Tawny Tabby, since Cream & White Tabby is dominant to Tawny Tabby Sadie had to have passed her hidden Scottish Blue & White. Thus making Tawny Tabby dominant to Scottish Blue & White.
The Abyssininan Creme proof is much more straightforward, it was pulled from under the Blue & White by the much more recessvive Aussie Snow.
Great work Violet. I have been running a Cocoa & White test for a couple of weeks with mixed results. I had the Cocoa & Whites plus some Tawny Tabbies to pop open and was trying to get an indication which to test so I'll pop both babies from the cocoa & white test later
