Health and welfare issues
Hypertrophic Cardiomyopathy (HCM) may be inherited in this breed.
We have limited the information about inherited disorders to those conditions that are known and proven to exist within a breed. For many breeders and many conditions, insufficient information may be available at this time to know whether any particular breed is necessarily free of any particular condition.
In general, pedigree breeds use a much smaller gene pool for breeding than domestic cats and therefore have a higher risk of developing inherited disorders. In addition, a number of ‘newer’ pedigree breeds are derived from matings between one or more ‘older’ breeds, and in these situations, the perpetuation of inherited problems that were seen in older breeds is likely within the newer breeds.
