Thank you Arwen... that's a very clear display.
I wanted to add that KittyCats proofs - like geometical proofs - are rigorous demostrations that can be read in
only one way.
That is to say that if there is any ambiguity in the pedigree that cannot be resolved to a fact by more unambiguous info (usually another pedigree, sometimes the proven date of a line), it isn't a proof.
It may be "suggestive" but it isn't a proof.
So in Arwen's russian white demonstration, virtually all of those russian whites can be described as" russian white hiding russian white or rec" and we don't know what the "hidden" or "rec" is. Arwen got the kitties, tested and found out that the hidden was aussie dark chocolate.
And that's the way it has to be with a Proof; we generally have to pull the hidden to find out what's true about the cats. Most of the one-page proofs up on the forum take the form of the pull of the hidden to show - without any ambiguity - one trait showing and the hidden trait displayed.
Wendi and Charles did several lectures on doing proofs which can be found here:
The Proof is in the Pussy 1
The Proof is in the Pussy 2
