What the proposed field says, and why it reads that way. A carrier of a variant with no published allele, on no named line. This is the group bare 161 exists for. 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

The trace

Nothing stands above this cat, because this cat is where the line begins. A trace runs upwards, from an animal through its parents to the head of a line, and this animal is that head. Its own parents are not recorded. 91 records stand below it in the register, 23 of them its own offspring.

Recorded ancestry, 4 generations

What this page does not establish

This cat has a laboratory result. The grade above says which kind.

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.
