The average lifespan of a Maine Coon cat ranges from 12 to 15 years. Proper care, including a balanced diet, regular exercise, and routine veterinary check-ups, can contribute to a longer and healthier life. Maine Coons are a robust breed, but their longevity can be affected by certain genetic conditions like hypertrophic cardiomyopathy and hip dysplasia. Early detection and management of these conditions are crucial in extending their life expectancy. Providing a safe and stimulating environment is also beneficial for their overall well-being.
