I have a PhD in Microbiology... specifically bacterial infections of the cornea due to contact lens wear.
Thanks for the compliment on Zari, we adore her and she did very well as a show cat right up until she got so ill last Labor Day :-( She and Hunter (Mike and Sandy's lovely show alter) basically grew up in the show halls side by side.
I'm not sure about "replicating"... as biology is such a funny thing that you can hardly ever get exactly the same result each litter. What I have seen is that the three litters I have had from Nadiya bred to Zak (Zari's parents) they have been consistently really nice and I have found it hard every time to choose a favorite. Because of Zari's illness (still no diagnosis although they've ruled out almost everything) we have kept another girl from the last litter... Dalila. She's very different from Zari in coloring but I think still a really nice girl.

Dalila is the one on the left... as you can see none of the four (three girls and a boy) turned out like Zari! Forgive their bugged out eyes, first professional shoot and they were very excited by the wand toy he was whizzing about! LOL!
