To add your cat(s) please provide the following:

  • Cat's Name
  • Cat's Parents' Names (titles not necessary)
  • Breeders' Name(s)
  • Owners' Name(s), cattery name & contact information
  • First or repeat test
  • Official HCM testing results signed by a licensed veterinarian
  • Date and cause of death, if applicable

This site is purely voluntary on the part of the breeders and has no affiliation with the clinics or vets performing the tests. This site will not contain those cats who may be thought to be normal as a result of their parents being tested, if the offspring themselves are not tested.

Please send all official documentation by e-mail to:
cheryl@winterfyre.com.

If you would prefer to fax your official results, please contact me at the e-mail address above.

Note: it is recommended that Norwegian Forest cats intended for breeding be tested for HCM when the cat is at least one year old and then repeated annually until the cat reaches five-six years of age. There is unfortunately no way to guarantee that a cat listed in our database will not develop these conditions over time. We ask that breeders notify us if a cat's status changes, but we have no way to guarantee this will happen.
