How long do Maine Coons live?

Lifespan can be affected by genetics and health conditions such as hypertrophic cardiomyopathy (HCM), which is one reason cardiac and genetic screening in breeding cats is such a common focus for responsible breeders. But genetics is only part of the picture — day-to-day care has a real, cumulative effect on how many good years a cat gets. Keeping a Maine Coon at a healthy weight throughout life is one of the most impactful things an owner can control, since excess weight puts strain on joints and organs and is linked to a shorter, less comfortable lifespan in cats generally. Given how large-framed the breed is, it can be easy to under-notice early weight gain, so periodic weigh-ins as part of vet visits are worth keeping up.

Diet quality, dental care, and an indoor (or safely supervised outdoor) lifestyle all factor in as well — indoor cats are generally shielded from the vehicle strikes, predators, and infectious disease exposure that shorten outdoor cats' lives considerably. Regular veterinary checkups also matter less for catching one big problem than for catching small trends early: gradual weight change, subtle bloodwork shifts, or early dental disease are all far easier to manage caught early than late.

With attentive care, it's not unusual for well-bred, well-kept Maine Coons to reach the higher end of the range or beyond into their late teens.
