Maine Coon Health Guide — Heart, Joints, and Long Life
2026-05-19 · 8 min read
Maine Coons are generally healthy but have specific genetic conditions to watch for. Here's everything you need to know to keep your Maine Coon thriving.
Maine Coons are generally a robust, healthy breed with a lifespan of 12–15 years. However, their large size and genetics make them prone to a few specific health conditions that every owner should know about.
**Hypertrophic Cardiomyopathy (HCM)**
HCM is the most serious health concern for Maine Coons. It's a genetic heart condition where the heart muscle thickens, reducing its ability to pump blood effectively. Maine Coons have a higher prevalence of HCM than most other breeds. Reputable breeders screen for the HCM gene mutation (MyBPC3). Annual cardiac ultrasounds are recommended for Maine Coons over 3 years old. Signs include rapid breathing, lethargy, and reduced appetite.
**Hip Dysplasia**
Their large frames make Maine Coons prone to hip dysplasia — a malformation of the hip joint that causes pain and arthritis. Keep your Maine Coon at a healthy weight to reduce joint stress. Joint supplements with glucosamine and chondroitin can help. Provide ramps or steps to help older Maine Coons reach their favorite spots without jumping.
**Spinal Muscular Atrophy (SMA)**
SMA is a genetic condition that causes muscle weakness in the hind limbs. Affected cats have a distinctive swaying walk and may have difficulty jumping. It's not painful and affected cats can live normal lives, but reputable breeders test for the SMA gene.
**Grooming**
Maine Coons have a thick, semi-water-resistant double coat that needs brushing 2–3 times per week. Use a wide-tooth comb to work through the undercoat, then a slicker brush to smooth the top coat. During spring shedding season, daily brushing prevents matting and reduces hairballs.
**Dental Health**
Maine Coons are prone to periodontal disease. Brush teeth 2–3 times per week and provide dental treats. Annual professional dental cleanings are recommended.
