What the proposed field says, and why it reads that way. A carrier with no result of its own and one identified variant standing above it. The scheme is set out in full in the proposal. No registry issues this field today: it is computed from this cat's record at each build, so it changes by itself the day a laboratory result is entered, and nothing here has to be reissued.

What the register holds

Evidence grade
Reported — asserted, with neither a test nor a traced descent
Variant
none identified for this cat
Line
None traced. This cat is named to the German Longhair (C14) line by a source, and no descent is recorded
Connection
named to the German Longhair (C14) line by a source; the register holds no parentage that shows it

The German Longhair (C14) name on this cat is an attribution, not a traced descent. A source, usually a breeder-compiled chart, places it in that line. The register holds no chain of parentage that confirms or denies it.

The trace

The founders this cat descends from

No line is named for this cat, and it nonetheless descends from a founder this register holds. The chain is reached by unbroken parent links.

The grade above and this trace are not in conflict. The grade describes what is known about the variant, and no source asserts one for this cat. The trace is parentage, assembled by this survey from the documents behind each step. A cat can have a fully documented descent and still have nothing said about which variant, if any, came down it.

What this page does not establish

This cat has never been tested. Everything above rests on documents and descent. Descent from a line is not a genotype. A cat can stand in a line and carry nothing, and a blue eye can be caused by white, by colourpoint or by low iris pigment with no PAX3 variant involved.

This is not a health certificate. It says nothing about hearing, and nothing about whether this cat should be bred from. Deafness in this trait is associated with carrying two different variants at once, which no pedigree can show and only a test can.

What would change this page

This directory is built from what people send it. For this cat it does not hold:

Sending a pedigree, a photograph or a test result. A pedigree has to be one a registry or club issued, because that is the only document that settles a parent; a breeder chart is welcome but is recorded at a lower grade and cannot draw a descent. The contact page says what to send and how. A correction is as welcome as an addition: where this page is wrong about your cat, the record is changed and the source you supply is named on it.

Blue Eyes Directory · blueeyesdirectory.com · generated 14 September 2026 from the register. The register is compiled from published charts, registry documents and breeder statements, each named on the cat's full record. Where two sources disagree the record says so and does not choose between them.
