Thread: Tangaloor warning

Hi,

I'm so sorry for your loss. If the sire to your Maine Coon was Kititas Tangle Awjasper (Kititas Tangle Awjasper) - well, the Coonyham lines are a well-known source of HCM. The possible dam Gypsy (Tangaloor Kalua-http://www.pawpeds.com/db/?a=p&id=253278&g=4&p=mco&o=substring) has Coonyham as well.

Maine Coons commonly develop HCM when they are mature adults, so negative echocardiogram results at ages 2-3, etc., do not insure that a breeding cat is HCM free. There is a DNA test available now for one HCM-causing genetic defect, however we know there are other defects that cause HCM as well, since many Maine Coons with HCM do not carry the known defect. In purchasing a Maine Coon, it is best to be very careful about ancestry, avoid DNA-positive cats, and insist on a multi-year history of serial negative echocardiograms.
