Våren 2016 framkom det att det förekommer en defekt i rasen som innebär att det i vissa kullar föds dvärgväxta kattungar. Alla dvärgväxta kattungar har ett ganska likartat utseende och en gemensam nämnare är också att de alla har en och samma katt på både mammans och pappans sida i stamtavlan. I dagsläget har vi vetskap om ett 40-tal kattungar, men gissningsvis finns det ett ganska stort mörkertal. De drabbade kattungarna har fötts både i Sverige och utomlands.
SRC:s artiklar om dvärgväxt finns att läsa nedan på denna sidan.

The cat is ES*Patriarca Gucci*. She is born 2001 and is present at leas once in both mothers and fathers side in the pedigree of all affected kittens. Be careful and check your pedigrees further back than 2001 when searching for her.
* The cat’s name is published with the owners approval.
- Do not mate two potential carriers to each other
- Be restrictive when selling cats and kittens for breeding until a DNA-test is present
- If possible – try to plan matings that are free from potential carriers on both male and female side of the pedigree
- If you have, or are about to sell a cat for breeding that is a potential carrier – inform your buyer that the cat should not be mated to another potential carrier. Refer the buyer to SRC’s webpage for information in swedish or english
SLU is currently working to locate the defective gene.
We want to emphasize that this is a problem that only affects the breeders’ work. If you own or think about buying a pet ragdoll with Gucci in the pedigree, you do not have to worry. Only those kittens that are dwarf kittens are affected by the gene. The affected kittens are discovered several weeks before delivery, but do not hesitate to ask your breeder or us at SRC for advice if there is something you are unsure about.
The current pedigree line with Gucci has become popular due to the fact that there are plenty of friendly and good looking ragdolls in this line.
This cat is present in the pedigree of almost half of the number of registered ragdoll litters in SVERAK 2016. It is a common bloodline that many Swedish breeders have in their lines today. To completely remove so many healthy cats from the breeding population would be devastating to the breed.
Project Dwarfism focuses on the ~45 kittens affected by dwarfism where a clear connection between symptoms, appearance and pedigree can be distinguished. It is important to know that dwarfism can affect all breeds and for many different reasons, but in these kittens, there has been a clear common inheritance pattern detected through mapping. That’s why SLU took an interest in our problem and is currently working to try to get a DNA-test for this type of dwarfism.
The SRC has neither the resources nor the competence to evaluate any connection with other dwarfs. At this time, we only report results that come directly from SLU.
