Cats
golden from "wide band golden".
At birth, Siberian "Sunshine" resembles the early stages of the amber (ee) colour change in
Norwegian Forest Cats caused by a non-extension gene. However, the Siberian cats tested
negative for the amber gene. There were no genetic tests for Wide-band or for silver inhibitor,
let alone for Siberian sunshine, but it can be distinguished visually and by studying pedigrees.
Bimetallic colouration has also been seen in the Kurilian Bobtail and in random-bred cats in
the Ukraine.
Judge Lesley Morgan come across a number of strangely coloured cats that had been
nicknamed “bimetallic” as they displayed a mix of silver tabby and golden tabby in their
coats. The effect was beyond the rufousing or breakthrough colouring sometimes seen in
silver tabbies and in some cats the golden areas increased as the kittens grew into adulthood.
The only link she found was that every bimetallic Siberian she saw had close Polish ancestry
