Olivia from the Nice Cattery, held from chart material as Olivia Chatterie de Nice
prefix Chatterie de Nice · Siberian · line: Siberian, Altai or Barnaul unconfirmed · one blue eye · Variant not known
Under the variant field this directory proposes, this cat would read DBE 161p. A carrier of a variant nobody has sequenced, on no named line. This is the group bare 161 exists for. The proposal is set out in full here, and no registry issues this field today: it is computed from the record at each build and is not part of any registration.
How this cat is connected to the trait
NO RECORDED PARENT LINK JOINS THIS CAT TO A FOUNDER OR TO A TESTED ANIMAL. What the record rests on instead is the line recorded on it, Siberian, Altai or Barnaul unconfirmed, which is a source's attribution and not a descent this register can walk; and no recorded parent at all, which is a gap in the sources and not a statement that the cat had none.
No parent is recorded for this cat in the register, so no genealogy can be drawn. That is a gap in the sources, not a statement that the cat had none. Any offspring the register holds are listed below.
What is flagged
OLIVIA FROM THE NICE CATTERY, HELD FROM CHART MATERIAL AS OLIVIA CHATTERIE DE NICE. THE CATTERY NAMES HER AS THE FOUNDER OF ITS BLUE AND ODD-EYED LINES, AND SHE IS THE WEAKEST CASE IN THOSE LINES. Her own odd eye sits on extensive white spotting, which is exactly what the KIT white spotting gene does, so nothing about her appearance requires a dominant blue eye variant. HER RECORDED DESCENDANTS ARE A DIFFERENT MATTER: Omega Chatterie de Nice is SIB n 03 23 and Pavel Chatterie de Nice SIB n 09 24 61, both with TWO BLUE EYES ON MODEST WHITE, and white spotting covers an eye where the white falls rather than taking both. THE TWO OBSERVATIONS DO NOT SIT EASILY TOGETHER. Either the trait changes character down the line, or more than one thing is present in this cattery. THE REGISTER RECORDS BOTH AND RESOLVES NEITHER | THIS IS WHY A FOUNDER'S PHOTOGRAPH IS NOT A FOUNDATION. The cattery traces its programme to her; this survey cannot, because no pedigree, code or date is published for her and her phenotype is the ordinary one | THE ANIMAL A TEST WOULD BE WORTH MOST ON IN THIS CATTERY IS NOT HER BUT PAVEL CHATTERIE DE NICE, whose bilateral blue on a 09 coat is the thing the white does not explain, and who is the route into the Great Joy cats and Bonnie of Siberian Paws
A flag is not an error. It marks a place where two sources say different things, or where an attribution cannot be made on the evidence held.

The description held
ODD-EYED, ONE GREEN AND ONE BLUE, ON A CAT CARRYING A GREAT DEAL OF WHITE. The photograph shows white over the muzzle, a broad blaze, the whole chest and the front of the body. She is not dominant white and not colourpointed. AN ODD EYE ON AN EXTENSIVELY WHITE-SPOTTED CAT IS WHAT THE CLASSIC WHITE SPOTTING GENE ORDINARILY PRODUCES, so on her own appearance no variant is indicated

C3 blue-eyed Siberian breeder-compiled genealogy; and the Chatterie de Nice cattery's own page for OLIVIA, read 19 August 2026. A BREEDER'S PAGE FOR ITS OWN FOUNDER, in English, carrying a photograph. IT NAMES HER AS 'the progenitor of our blue and odd-eyed lines' and says her legacy is in many of the cattery's breeding lines and that the eyes are now the hallmark of the cattery. IT GIVES NO EMS CODE, NO DATE OF BIRTH AND NO PARENTS
This directory is a working aid compiled from published charts, registry documents and breeder statements. It is not a register and it has no standing of any kind. The grade attaches to the animal, not to the line: a cat whose ancestor was genotyped is line-traced, not genotyped.
