Tiger! - Purple Kiwi probably dominant to Australian Mist - Blue Marble.
I can take the Aussie - Blue pedigree back to a Aussie - Blue cat 1165 days old (it's gone thru several generations of Chat Pink and Whites on the way to Hughes, but it's solid and from very early Aussie - Blue.
I know simplest way to get the proof would be to breed the kitten, but I'm going to wait for a sibling as I didn't get the eyes I wanted. Sirena and Hughes are partnered and will carry on trying for the combination of fur and eyes that I want.
