Registering your 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 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 a five generation pure Siamese pedigree cannot be produced the cat will be placed on the Reference Register.
If the cat is registered as anything else such as a 'Thai Siamese' then it will be placed on the Reference Register. This is because many of these cats are not pure Siamese but can have other breeds in their background.
[It is important to note that 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.
The OSSC fully supports the GCCF registration policy regarding these cats.]
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.
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
and the Supplementary Register as CSSR.
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.
