A single normal echocardiogram does not guarantee a cat is free of disease. Therefore Sphynx should be screened on a routine basis.
Sphynx cats currently in or retired from breeding programs should have annual echocardiograms. Non breeding Sphynx should be scanned every 12 – 18 months to catch the thickening of the heart while there is time to treat the disease. Echocardiographic screening and the reporting of results and pedigrees to the Sphynx HCM Databases will also help reduce the incidence of HCM within the Sphynx breed if enough breeders and pet owners are involved.
