Hairless Heroes, the breeders on our registry, as well as many veterinarians strongly believe in a correlation between conscientious breeding practices and the occurrence of HCM in Sphynx. Based on studies and first-hand experience in breeding following simple, if stringent, criteria can make a serious difference in individual cats and the breed - for the better.


We conducted a survey of 80 HCM affected cats and these were the results:

Is your HCM positive cat registered? 

Yes 42.5%

No 41.3%

I don't know 16.3%


Did the breeder say they scanned their cats for HCM?

Yes 58.8%

No 26.36%

I don't know 15%


Did you get proof the parents were scanned?

Yes 30%

Does the breeder submit their scans to a database?

Yes 10%

No 42.5%

I don't know 47.5%


Did the breeder educate you about HCM or did you have to self-educate?

The breeder told me 3.1%

I had to educate myself 71.9%

The breeder told me, but I did my own research 25%


What was the length of their health guarantee?

No guarantee 51.2%

1 year 27.5%

2 years 8.8%

3 years 2.5%

4 years 2.5%

5 years 5%

6 years 2.5%
