Why this page?
Many people do not know what good or bad hips look like. Therefore,
and to help educate our visitors, this reference page was developed.
When completed, this page will contain X-rays of the various OFA grades of cat hips.
We hope this site is informative to you, our visitor. We also
hope that it will assist breeders in making the decision to have their cats
hips evaluated as well.

will extract much more information from the original pictures than you can possibly see here.

recognized, even when the hip joints are noticeably affected.
To prevent the intrusion of HD, several Maine Coon breeders have started to test
Fortunately breeders can reduce the risks significantly through the use of
X-ray photography, and then only using cats with hips rated Excellent, Good or Fair for breeding.
