Maine Coons are one of the largest domestic cat breeds, and that size brings a joint health profile more commonly associated with large dogs than with cats generally — including a documented, meaningful rate of hip dysplasia. Combined with a breed-associated heart condition, Maine Coon aging deserves a somewhat different lens than typical feline senior care advice.
Why Do Maine Coons Face Joint Issues Most Cats Don’t?
Most domestic cats are light enough that hip dysplasia is rarely a clinical concern, but Maine Coons’ significantly larger frame changes that calculus — the breed has one of the only well-documented rates of hip dysplasia among cats. Combined with their size, general joint wear from a larger body carrying more weight over a lifetime is also more relevant than in an average-sized cat.
What Other Health Issues Should Maine Coon Owners Watch For?
- Hypertrophic cardiomyopathy — a heart muscle condition with a notably higher rate in Maine Coons, for which a genetic test exists
- Spinal muscular atrophy — a rare inherited condition affecting some Maine Coon lines, worth knowing your cat’s genetic background if available
- General joint wear — simply a function of carrying a larger frame over many years, similar in principle to large dog breeds
How Should You Support an Aging Maine Coon’s Mobility?
- Ask your vet about hip and joint assessment as part of routine senior exams, not just for dogs
- Discuss cardiac screening or genetic testing for hypertrophic cardiomyopathy given the breed’s elevated risk
- Provide lower-step access to favorite perches and litter boxes as jumping becomes harder
- Keep the cat lean — for a naturally large breed, “big-boned” can mask genuine overweight status that adds unnecessary joint strain
