Fletcherfield's Jack the Ripper

prefix Fletcherfield · Maine Coon · DBE-RE · line: Rociri Elvis · both eyes blue · Genotyped · also in its ancestry: Pillowtalk-Foreigner

Under the variant field this directory proposes, this cat would read DBE 164p. The variant is attributed to this animal from the record rather than from a result on it. 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

Fletcherfield's Jack the Ripper, MCO n 09 22 68
Joyfield's Lenny Kravitz, MCO es 09 68, the sire of Fletcherfield's Jack the Ripper
Joyfield's Dolly, MCO g 09 68, the dam of Joyfield's Lenny Kravitz
Rociri Elvis, MCO e 09 68, the sire of Joyfield's Dolly. DBE-RE, adopted by this survey; a founder of this survey

That is 3 recorded parent links, and the animal at the end of it carries a variant this survey has adopted, but has not itself been tested. Every step is a parent recorded in this register from a document; none of them is an assumption. The full genealogy is drawn below, and the sources for each animal are on its own page.

What is flagged on this tree

ANVERSCOON GRENACHE. Resolved. WHICH PARENT IS THE SIRE IS NOW SETTLED BY A CHART. The register previously held both of this cat's parents as dams. The PawPeds pedigree for Joyfield's Survivor van Nous Deux read 17 August 2026 places MAINEFIELD'S OYE COMO VA IN THE SIRE POSITION and Aislinn's Exciting Blue in the dam position
ROCIRI ELVIS, GIVEN ON THE PEDIGREE AS ROCIRI'S ELVIS. HIS OWN SHEET, AND WHAT IS AND IS NOT ON IT. THIRTY ANCESTORS, ALL THIRTY UNIQUE, FOUR COMPLETE GENERATIONS, INBREEDING 0.0 PER CENT. THE 68 ON HIM IS THE ONLY 68 ON THE WHOLE DOCUMENT AND THE ONLY EYE CODE OF ANY KIND ON IT IS THE 63 ON JUSTCOONS HA SHISCH, MCO w 63, A DOMINANT WHITE ODD-EYED CAT IN THE THIRD GENERATION. His grandsire Mainefield's Oye Como Va is MCO w, also white, and carries no eye code. NO OTHER ANIMAL ON THE SHEET CARRIES AN EYE CODE AT ALL. THAT IS THE WHOLE OF THE EVIDENCE ABOVE HIM: two white cats, one of them odd-eyed, and twenty-eight animals with nothing recorded about their eyes. In a white cat an eye cannot be read either way, so the sheet neither supplies a source for his 68 nor rules one out, WHICH IS WHY THE PUBLISHED TRACE ABOVE HIM RUNS THROUGH WHITE CATS AND GOES COLD THERE
FLETCHERFIELD'S JACK THE RIPPER. Identity. TWO SHEETS, ONE CODE, ONE DATE, ONE PAIR OF PARENTS. Fletcherfield's Jack the Ripper and Fletcherfield's Blauer Klaus are both MCO n 09 22 68, both born 24 February 2020, and both out of Gonsior Line Allure by Joyfield's Lenny Kravitz. The sheets differ only in the country field, DE slash nothing against DE slash DE. EITHER ONE CAT CARRIES TWO NAMES OR THEY ARE LITTERMATES, and the survey does not choose: a prefix is gained on entering a programme and dropped on leaving it, and neither sheet carries a registration number that would separate them

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.

PawPeds pedigree supplied to the survey 16 August 2026, four complete generations, thirty ancestors of thirty possible, inbreeding 0.0 per cent. DESCENT FROM ROCIRI'S ELVIS IS ON THE FACE OF THE PEDIGREE, through Joyfield's Dolly and Joyfield's Lenny Kravitz. Genotyping through the Rociri Elvis line is stated to this survey; no individual laboratory report has been supplied, so the grade is line-traced and not genotyped

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.
