The main problem is that the largest registry in the UK, the GCCF, dos not accept cinnamon as a birman colour, so it is vital to keep this recessive gene out of the GCCF gene pool until it becomes acceptable in the registry, which may take many years due to the conservative nature of the exisiting birman clubs. However there is a simple DNA test available which identifies carriers of the gene, enabling me and any other breeders working with the colour to determine which cats are carriers and which are not. All kittens from a carrier of the gene will be DNA tested to ensure the gene does not enter the GCCF genepool undetected.
After much research into other initial cinnamon breeding programs and examination of type I decided that the only practical breed to use was the British Shorthair, mainly because other cinnamon breeds in the UK have oriental/foreign type, which would involved a great deal more work to return to the more moderate birman type. A breeder on the continent managed to use a cinnamon Neva Masquerade (pointed Siberian) as an initial outcross, which has proved very successful on type and size, and I hope to be working withher in the near future.
Our initial outcross was between a TICA and GCCF registered seal tortie pt birman to a TICA and GCCF registered cinnamon British Shorthair ( carrying LH) resulting in one male black LH carrier with white feet, one chocolate tortie shorthair, and a black tortie shorthair. The black tortie was homed as a pet, the chocolate tortie shorthair went to another breeder and I retained the male., the litter was registered with TICA with a AON registration number.
He was mated to a GCCF birman variant (blur tortie pt birman/persian) resulting in a TICA registered litter of 3, a red pointed male carrier, a seal tortie pt non-carrier and a solid tortie non-carrier. Both non-carriers were sold as pets, with the pointed seal tortie being shown successfully as a HHP. The variant was chosen for this initial mating to increase genetic diversity at an early stage, when the number of generations away from a 'full' birman was not so critical.
Below is Purindoors ReddyforCin, being shown as a HHP (known as 'Wotsit of Purindoors') at a TICA Show, where he gained best cat in 7 out of 8 rings due to his wonderful personality and looks.
So in 2 generations we have regained Longhair and pointed cats, however they are very similar in type and coat quality to BritishLonghair. Wotsit has a 'BON' TICA registration number.
This is Purindoors Sectet Cinna, our third generation cinnamon carrying boy at seven months old. Looks pretty much as a birman should, good eye colour, nice front wihtes although his guantlets are thin and thready. He also carries dilute.
The kids are still argunig over his pet name, with my youngest going for 'Thor' and one of the others insisting on calling him 'Alan' just to irritate his little brother. Unfortunately he seems to be answering to 'Alan' now.
