re-posting, as I had accidentally deleted...
Currently have a kittycorn/starter cat who carries British Shorthair C&W fur and Twilight eye, paired with an Aussie Dark Chocolate with Bronze eye. They have produced a Brit SH C&W with Twilight eye. The Test kitten is now paired with a Tonk Blue Mink /Dry Olive eyed mate to determine his hidden fur and eye.
I will update with info & additional pedigrees if/when we have more constructive results.
