Update: Comments have now been turned off to reduce any confusion in unofficial answers to questions. Any queries regarding the new policy should be directed to the GCCF Office in the first instance.
The British Shorthair Breed Advisory Committee has implemented an amendment to the British Shorthair Registration Policy regarding the Dominant Blue Eyes (DBE) genes.
With immediate effect, blue-eyed or odd-eyed cats of British Shorthair lineage in any colour or pattern other than epistatic dominant white, colourpointed, or colourpointed and white, will no longer be accepted as British Shorthairs in GCCF registrations.
The amended policy states:
Blue-eyed/odd-eyed cats of BSH appearance in any pattern other than epistatic dominant white, colourpointed or colourpointed & white shall be registered on the Reference Register with no progression as no recognised breed (XSH) and are not acceptable in the pedigrees of British Shorthairs.
As a result, any kittens expressing the Dominant Blue Eye trait and falling within the above description will be registered as Unrecognised Shorthair (XSH) on the Reference Register (not to be shown) and will not be eligible for progression within the British Shorthair breed. Unrecognised breeds/cats cannot be used for breeding.
This change applies to registrations submitted from the date the amended policy came into effect (27/06/26). Breeders with existing or planned matings involving DBE lines are encouraged to familiarise themselves with the updated policy before undertaking any matings relating to these genes.
Any queries regarding the new policy should be directed to the GCCF Office in the first instance.
