The proposed scheme writes no field for this cat. It codes carriers, and this animal is not recorded as one; where two causes of a pale eye stand together on a single record the scheme also leaves the cat unknown rather than coding it either way. The proposal sets out both cases.

Read this as parentage and nothing more. Each step is a parent recorded in the register from a pedigree or a breeder document. It shows how this cat descends from the founder of its line. It does not show which variant the cat carries, and it is not a substitute for a test.

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:

• a photograph, which settles an eye colour and the extent of any white far better than a code does

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.
