Maine Coon Lifespan and Health: What Owners Need to Know
Maine Coons are generally healthy, long-lived cats — but like all purebred cats, there are breed-specific health considerations that informed owners should understand.
The Challenge
The health issue that comes up most often in Maine Coon communities is HCM — hypertrophic cardiomyopathy, a heart muscle thickening that's more prevalent in the breed than in the general cat population. It sounds alarming, but the risk is manageable with regular screening. The bigger problem is owners either ignoring it entirely or becoming anxious about every symptom, neither of which serves the cat well.
What We've Found
Responsible Maine Coon ownership means choosing a breeder who health-tests breeding cats for the HCM genetic mutation (MyBPC3) and scheduling an echocardiogram with a veterinary cardiologist at around age two and every two to three years thereafter. Hip dysplasia is the other consideration — evident in some cats as a rear leg gait change. Most Maine Coons live well into their teens with no major health events when these conditions are monitored rather than ignored.
