Breeding Policy
Cornish Rex (CRX)
This document is seen as a way of ensuring breeders observe what is considered 'best practice' in their involvement with Cornish Rex and particularly in their Cornish Rex breeding programmes.
Cornish Rex, unlike most breeds, owe their origin to one cat - Kallibunker. Inbreeding was carried out in the early generations in order to produce the three generations of Rex to rex breeding needed to obtain breed recognition. This practice of inbreeding has continued. Some Cornish Rex do have Devon Rex ancestry due to the initial breedings that took place between Kirlee (the original Devon Rex) and Kallibunker's female descendants when it was assumed Kirlee resulted from the same mutation as Kallibunker. Two blood types have been confirmed in Cornish Rex - type A and type B. Type A is dominant over type B. This means that a cat with type B blood is homozygous for B. type A cats can either be homozygous for A or heterozygous (carrying the B gene). Cats with type B blood have strong antibodies against type A red blood cells. These anti-A antibodies can cause two serious problems : Neonatal Isoerythrolysis (Fading kitten syndrome) and transfusion reactions.
Aims
It is vital regular selective outcrossing be introduced and maintained to increase the gene pool and maintain stamina and health. This is 'best for the breed' in its ongoing development.
Guidelines
Breeders and owners of Cornish Rex and Cornish Rex Variants are recommended to blood type test all their cats but more especially all breeding stock. Blood type A kittens resulting from a mating between a type A stud and a type B queen may die within the first few days of life if allowed to suckle their mother's clostrum. It is also important to know that cats with the relatively rare type B blood can die if given a transfusion of the common type A blood.
All cats used for outcrossing should be thoroughly researched, of sound temperament and free from any hereditary defects.
Breeders should ensure, to the best of their knowledge, any Cornish Rex or Cornish Rex Variants from which they breed are of sound temperament, free from any hereditary defects, (including those listed in the GCCF Standard of Points), and conform as closely as possible to the Standard of Points (excluding the coat description where variants are concerned).
Cornish Rex are not compatible with Devon Rex. Such matings are therefore highly undesirable. The product of such matings will be registered on the Reference Register and cannot be considered to be variants. They cannot be used in either Rex breeding programme and should be placed on the non-active register. It is considered to be in the best interest of the Cornish Rex breed to keep it entirely separate from other incompatible Rex mutations.
Under no circumstances should any cat with Sphynx ancestry be introduced into the Cornish Rex breed. Selection for hairlessness contradicts the coat quality requirements for Rex cats. The product of any matings between Sphynx and Cornish Rex will be registered on the Reference Register. They cannot be considered to be variants nor be used in any Cornish Rex breeding programme and should be placed on the non-active register.
Breeders are recommended not to breed from Cornish Rex or Cornish Rex variants with Long Hair. The long-hair gene has been present in the breed since its accidental introduction in 1959/60. It is considered in the best interest of Cornish Rex coat quality not to perpetuate this factor. Outcrosses made to breeds with Long Hair ancestry should be undertaken with caution. Where possible Breeders are urged to use only cats proven not to be carriers of the long-hair gene.
Breeders shall ensure that any Cornish Rex or Cornish Rex Variants from which they breed, shall be registered with the GCCF in accordance with the Rules in force at the time.
It is recommended that the progeny from any matings that are not required for Cornish Rex breeding, should be placed on the Non-Active Register, to avoid the introduction of the Cornish Rex gene into other varieties of pedigree cats.
The majority of matings are most likely to be between Cornish Rex x Cornish Rex and Cornish Rex x Cornish Rex Variant, but to ensure maximum benefit from outcrossing Cornish Rex Variant x Cornish Rex Variant matings are necessary. Normal coated progeny from Variaot x Variant matings cannot be considered variants as this can only be proven by test matings.
Breeds which have been approved for use in outcrossing are: Abyssinian, Asian Shorthair, British Shorthair, Burmese, Oriental, Russian Blue, Siamese.
All other breeds are listed as non-approved.
Breeders will be encouraged to take advantage of any relevant official scheme, which may be devised by the Cornish Rex & Devon Rex Joint BAC to test the soundness of the Cornish Rex breed.
Note: It is recommended where the colour of a cat is in question a DNA test, (where such a test exists), be arranged.

Devon Rex (DRX)
This document is seen as a way of ensuring breeders observe
what is considered 'best practice' in their involvement with Devon Rex and
particularly in their Devon Rex breeding programmes.
Devon Rex, unlike most breeds, owe their origin to one cat -
Kirlee. It should always be remembered that most of the females bred to Kirlee
were very closely related as well as being immediate descendants of Kallibunker
- the original Cornish Rex, as at that time it was assumed Kirlee resulted from
the same mutation as Kallibunker. Inbreeding was then carried out in the ensuing
generations to produce the three generations of Rex to Rex breeding needed to
obtain breed recognition. This practice of inbreeding has continued. From the
beginning, serious health problems have beset Devon Rex, i.e. Luxating Patellae,
Coagulopathy and Inherited Myopathy (Spasticity). Two blood types have been
confirmed in Devon Rex - type A and type B. Type A is dominant over type B. This
means that a cat with type B blood is homozygous for B. Type A cats can either
be homozygous for A or heterozygous (carrying the B gene). Cats with type B
blood have strong antibodies against type A red blood cells. These anti-A
antibodies can cause two serious problems : Neonatal Isoerythrolysis (Fading

LaPerm (LPL Longhaired/LPS Shorthaired)
Aims
This document is seen as a way of ensuring breeders observe what is considered 'best practice' in their involvement with the LaPerm and particularly in their LaPerm breeding programmes.
It is vital that regular selective outcrossing is maintained to increase the gene pool and improve stamina and health. When breeding curly to curly it is vitally important that careful selections are made to ensure low inbreeding co-efficients. This is 'best for the breed' in its ongoing development.
Guidelines
The LaPerm gene (Lp) is dominant so LaPerm Variants do not carry the LaPerm gene, but may be useful in breeding programmes when mated back to LaPerms. LaPerms may carry the straight haired gene recessively so LaPerm x LaPerm matings can produce LaPerm Variants. LaPerms which carry the straight haired gene are known as Heterozygous LaPerms. Homozygous LaPerms do not carry the straight coated gene and will produce only rex coated offspring. There are no differences in appearance between Homozygous and Heterozygous LaPerms. The eventual aim of the LaPerm breeding programme is to produce Homozygous LaPerms but while the breed is still developing it is important to maintain breeding with both Homozygous and Heterozygous LaPerms.
The majority of matings are most likely to be between LaPerm x LaPerm, LaPerm x Approved Outcross Breed and LaPerm x LaPerm Variant. Matings between LaPerm Variant x LaPerm Variant cannot produce LaPerms but the offspring of such matings may be registered as LaPerm Variants.
Breeders should ensure, to the best of their knowledge, that any LaPerms or LaPerm Variants from which they breed are of sound temperament, free from any hereditary defects, (including those listed in the GCCF Standard of Points), and conform as closely as possible to the Standard of Points, (excluding the coat description where variants are concerned).
All cats used for outcrossing should be thoroughly researched, of sound temperament and free from any hereditary defects. Blood type B appears to be very rare in the LaPerm. It is recommended that cats with blood type B should not be introduced into the LaPerm breeding programme in order to prevent the occurrence of problems with blood type incompatibility.
LaPerms are not compatible with Cornish, Devon or Selkirk Rex. Such matings are therefore highly undesirable. The product of such matings will be registered on the Reference Register and cannot be considered to be LaPerms or LaPerm Variants. They cannot be used in any Rex breeding programme and should be placed on the non-active register. It is considered to be in the best interest of the LaPerm breed to keep it entirely separate from other incompatible Rex mutations.
Under no circumstances should any cat with Sphynx ancestry be introduced into the LaPerm breed. Selection for hairlessness contradicts the coat quality requirements for Rex cats. The product of any matings between Sphynx and LaPerms will be registered on the Reference Register. They cannot be considered to be variants nor be used in any LaPerm breeding programme and should be placed on the non-active register.
Breeders shall ensure that any LaPerms or LaPerm Variants from which they breed, shall be registered with the GCCF in accordance with the Rules in force at the time. It is recommended that the progeny from any matings that are not required for LaPerm breeding, should be placed on the Non-Active Register, to avoid the introduction of the LaPerm gene into other varieties of pedigree cats.
Breeds which have been approved for use in outcrossing are:
Somali, Abyssinian, Ocicat, Asian Shorthair, Tiffanie, Burmese (European Burmese in the case of imported cats), Tonkinese, Oriental SH, Oriental LH (Angora), Siamese and Balinese plus variants of these breeds.
All other breeds are listed as non-approved.
“Old fashioned” type is recommended for Siamese, Balinese, Oriental SH and Oriental LH (Angora) cats used for outcrossing and cats of extreme type should be avoided.
Domestic longhairs and shorthairs were used in the development of the breed in the USA and may appear in the background of the pedigrees of imported cats.
A wide range of breeds has been permitted for outcrossing during this early development of LaPerms in the UK in order to establish a large healthy gene pool. It is anticipated that the number of permitted outcross breeds will be reduced as LaPerms progress.
Breeders will be encouraged to take advantage of any relevant official scheme, which may be devised by the BAC to test the soundness of the LaPerm breed.

Reference Register I
- LaPerm Variants which have within the preceding five generations only LaPerms, LaPerm Variants, Somali, Abyssinian, Ocicat, Asian Shorthair, Tiffanie, Burmese (European Burmese in the case of imported cats) and Tonkinese plus variants of these breeds, shall be registered on the Reference Register with a LaPerm Variant breed number. Cats of unknown parentage but registered as "of LaPerm type", or cats which have been granted a registration number for use in the LaPerm breeding programme but are referred to by another organisation as "Domestic LH" or "Domestic SH" are permitted in the pedigrees of cats registered (either with GCCF or with another bona fide organisation) prior to 23rd June 2004. In addition, unregistered domestic LH and SH are permitted in the fourth and fifth generations of pedigrees of cats registered (either with GCCF or with another bona fide registering organisation) prior to 23rd June 2004, and those of their descendants.
- LaPerms and LaPerm variants which have within the preceding five generations any non-approved breeds and registered prior to (date of
progression to Provisional status) shall be registered on the Reference Register as normal or rex coated of LaPerm type. This includes unregistered domestic LH and SH, with the exception of those in the pedigrees of cats registered (either with GCCF or with another bona fide registering organisation) before 23rd June 2004, and those of their descendants.
NB. When kittens with one or both parents registered on the Reference Register are, under this Registration Policy, eligible to be registered on the Supplementary Register it is recommended that the person registering these kittens requests such registration and encloses documentary evidence of the five generations required. If this is not done the kittens may be registered on the Reference Register.
Note: Chinchillas (10) permitted in background of Asian SH/Tiffanie pedigrees are also permitted in fourth and fifth generations of LaPerm pedigrees.
All cats resulting from matings between LaPerms and any breed other than those listed above as acceptible in LaPerm pedigrees shall be registered on the Reference Register as 'No Recognised Breed' with no progression.
-
Note 1: LaPerms with Oriental SH, Oriental LH, Siamese or Balinese cats in their pedigrees registered prior to (date of progression to Provisional status), will continue to be registered as LaPerms, as will their progeny in succeeding generations. After (date of progression to Provisional status) the progeny of LaPerms mated to Oriental SH, Oriental LH, Siamese or Balinese will be registered on the Reference Register as 'no recognised breed' with now progression.
- Note 2: Before the registration of any white LaPerm or white LaPerm Variant, a BAER certificate of freedom from deafness for the white parent(s) must be supplied to the GCCF. For identification purposes cats must be micro chipped prior to testing.
Selkirk Rex (SRL Longhaired/SRS Shorthaired)
This document is seen as a way of ensuring breeders observe 'best practice' in their involvement with the Selkirk Rex and particularly in their Selkirk Rex breeding programmes.
Selkirk Rex, unlike most other breeds, owe their origin in 1987 to one cat Miss DePesto. Inbreeding was carried out to establish if this was a new, or already established gene. It was found that Miss DePesto was a new mutation of a complete dominant nature unlike the Devon and Cornish Rex which are both produced by a recessive gene. The Selkirk Rex may be homozygous (have two Rex genes) or heterozygous (have one Rex gene) and may be long or shorthaired. To produce Rex coated kittens at least one parent must be a Selkirk Rex. Straight coated Selkirk Rex Variants do not carry the Rex gene but are useful for breeding because the best exhibition Selkirk Rex are heterozygous.
Two blood types have been confirmed in Selkirk Rex - type A and type B. Type A is dominant over type B. This means a cat with type B blood is homozygous for B. Type A cats can be either homozygous for A or heterozygous (carrying the B gene). Cats with type B blood have strong antibodies against type A red blood cells. These anti-A antibodies can cause two serious problems: Neonatal Isoerythrolysis (fading kitten syndrome) and transfusion reactions.
Aims
It is vital regular selective outcrossing be maintained to increase the gene pool and maintain stamina and health. This is 'best for the breed' in its ongoing development.
Guidelines
Breeders and owners of Selkirk Rex and Selkirk Rex Variants are recommended to blood type test all their cats but more especially all breeding stock. Blood type A kittens resulting from a mating between a type A stud and a type B queen may die within the first few days of life if allowed to suckle their mother's colostrum. It is also important to know that cats with the relatively rare type B blood can die if given a transfusion of the more common type A blood.
PKD has been confirmed in Selkirk Rex. Breeders are advised to buy only from PKD tested stock and to breed only with cats, including ALL outcrosses, which have been screened or DNA tested PKD clear under a recognised scheme (the FAB/PKD scheme in the UK).
All cats used for outcrossing should be thoroughly researched, of sound temperament and free from any hereditary defects.
Breeders should ensure, to the best of their knowledge, that any Selkirk Rex from which they breed are of sound temperament, free from any hereditary defects, (including those listed in the GCCF Standard of Points), and conform as closely as possible to the Standard of Points (excluding the coat description where variants are concerned).
Selkirk Rex are not compatible with either Cornish Rex, Devon Rex or LaPerms. Such matings are therefore highly undesirable. The product of such matings will be registered on the Reference Register and cannot be considered to be variants. They cannot be used in any Rex breeding programme and should be placed on the non-active register. It is considered to be in the best interest of the Selkirk Rex breed to keep it entirely separate from other incompatible Rex mutations.
Under no circumstances should any cat with Sphynx ancestry be introduced into the Selkirk Rex breed. Selection for hairlessness contradicts the coat quality requirements for Rex cats. The product of any matings between Sphynx and Selkirk Rex will be registered on the Reference Register. They cannot be considered to be variants nor be used in any Selkirk Rex breeding programme and should be placed on the non-active register.
Breeders shall ensure that any Selkirk Rex or Selkirk Rex Variants from which they breed, shall be registered with the GCCF in accordance with the Rules in force at the time. It is recommended that the progeny from any matings that are not required for Selkirk Rex breeding, should be placed on the Non-Active Register to avoid the introduction of the Selkirk Rex gene into other varieties of pedigree cats.
The majority of matings are most likely to be between Selkirk Rex x Selkirk Rex and Selkirk Rex x Selkirk Rex Variant, but to ensure a healthy gene pool outcrosses are essential.
Breeds approved for use in outcrossing are: British Shorthair (including longhaired Variants), Persian and Exotic (including Variants). All other breeds are listed as non-approved. In addition, for cats bred outside the UK, American Shorthair was an approved outcross until 31.12.97 when it was discontinued.
All other breeds are listed as non-approved.
Breeders will be encouraged to take advantage of any relevant official scheme, which may be devised by the Joint Rex BAC to test the soundness of the Selkirk Rex breed.
Note: It is recommended where the colour of a cat is in question a DNA test, (where such a test exists), be arranged.
