<P> Pet insurance data obtained from a study during years 2003 -- 2006 in Sweden puts the median lifespan of the Maine Coon at > 12.5 years . 74 % lived to 10 years or more and 54 % lived to 12.5 years or more . Maine Coons are generally a healthy and hardy breed and have adapted to survive the New England climate . The most severe threat is feline hypertrophic cardiomyopathy ( HCM ) , the most common heart disease seen in cats , whether pure bred or not . In Maine Coons , it is thought to be inherited as an autosomal dominant trait . Middle - aged to older cats as well as males are thought to be predisposed to the disease . HCM is a progressive disease and can result in heart failure , paralysis of the hind legs due to clot embolization originating in the heart , and sudden death . A specific mutation that causes HCM is seen in Maine Coons for which testing services are offered . Of all the Maine Coons tested for the MyBPC mutation at the Veterinary Cardiac Genetics Lab at the College of Veterinary Medicine located at Washington State University , approximately one - third tested positive . Not all cats that tested positive will have clinical signs of the disease and some Maine Coon cats with clinical evidence of hypertrophic cardiomyopathy test negative for this mutation , strongly suggesting that a second mutation exists in the breed . The HCM prevalence was found to be 10.1 % ( 95 % CI 5.8 - 14.3 % ) in this study . </P>
