Registering your SIAMESE breeding cats with the GCCF
The following is to assist breeders new to the GCCF to understand the steps required to register their cats on the GCCF Registers and how their breeding cats may qualify as pure Siamese if they have not previously been registered with the GCCF. The OSSC is a GCCF affiliated Club and therefore its focus is on the GCCF's rules and requirements.
The OSSC requires that all kittens placed on the kitten list must be GCCF registered. (No other registry would allow GCCF kittens to be placed on their sites). This applies to all kittens whether on the Active Register or Non Active Register.
For cats that are registered with another registering body, in order to be placed on the GCCF Full Register, they must be able to present to the GCCF a five generation certified pedigree showing pure Siamese breeding. If that is not possible then the rules shown below are applied.
If the cat is registered with another registering body and is registered as a Siamese but has less than five generations of pure Siamese breeding, that cat will be placed on the Reference Register. This assumes that a certified pedigree can be produced as evidence.
If the cat is registered as anything else such as a 'Thai Siamese' then it may be placed on the Reference Register. Sometimes the GCCF will not register these cats as they do not recognise the pedigree as showing a Siamese cat. IF THIS IS THE CASE PLEASE CONTACT THE OSSC GCCF DELEGATE WHO WILL TRY AND ASSIST YOU WITH THIS PROBLEM.
[It is important to note that some of the 'Thai Siamese' are not 'pure Siamese' but may have other cats in their background. In Europe Siamese cats were mated out to shorthaired cats to modify type. The progeny mated back to Siamese and by generation F3 the cats were called 'Thai Siamese' and mated to each other.
The same applies to the 'Thai Siamese' from Thailand. Some will be Tonkinese Colourpoint Variants and others hybrids of Thailand street cats. Although they may have inherited the 'Siamese gene' from both parents, giving a 'pointed pattern', the head shape, eye colour, coat pattern, which can include white spots, indicate that they are hybrid cats and not Siamese. Photographs of these 'street cats' are available on web sites of breeders who have imported them. A quote from another internet site 'just because it comes from Thailand does not mean the cat is Siamese'. Testing is futile as the colourpoint cats will all show a double cscs gene.]
Cats that are on the Reference Register require three generations of mating to pure Siamese before the progeny (F3) will be placed on the Supplementary Register. [The rule used to require six generations (F6) before any cat could be placed on the Supplementary Register.]
The progeny (F3) on the Supplementary Register require three further generations of mating to pure Siamese before the progeny (F6) can be placed on the Full Register. [Again this is far less than in the past when twelve generations (F12) were required to progress to the Full Register.]
Siamese which are the result of mating with an Oriental or, the result two Orientals producing the Siamese pattern, are placed on the Supplementay Register. In order to qualify for the Full Register the progeny must be mated to pure Siamese for six generations (F6).
All cats on the Supplementary Register are treated the same as the Full Register for purposes of showing in GCCF shows.
This club supports introducing cats from the USA and Thailand into our lines to widen our gene pool. We believe that even on the Reference Register this is beneficial as within three generations the progeny can be placed on the Supplementary Register, and within another three generations the Full Register. We see no difference between this and introducing Oriental cats into Siamese lines, the Siamese produced from these matings requiring six generations to reach the Full Register.
The Register that the cat is placed on is indicated on the registration certificate.
On older registration certificates the Reference Register is shown as CSRef, the Supplementary Register as CSSR and the full register as CS.
In addition cats/kittens will be placed on the Active or Non-Active Register.
Active register allows the cat to used for breeding and kittens registered with the GCCF.
Non-Active register means the cat should not be used for breeding. Any progeny from this cat cannot be registered with the GCCF.
If a queen is on the Full Register and the stud is not (or vice versa) it is possible to clarify with the GCCF before the mating on which list the kittens will be placed.
