How to Help Your Maine Coon Live Longer
-
Feed a quality, breed-appropriate diet
Maine Coons need 220–380 kcal/day. Avoid overfeeding — obesity can shorten a cat's life by 2+ years.
-
Exercise 30 minutes daily
Regular activity maintains muscle mass, healthy weight, and cardiovascular health — all key longevity factors.
-
Keep teeth clean
Dental disease affects most cats by age 3. Brush teeth weekly or use dental chews to prevent bacteria reaching vital organs.
-
Regular vet check-ups
Annual exams catch problems early. After senior age, twice-yearly visits are recommended.
-
Keep them mentally stimulated
Puzzle feeders, training, and new experiences reduce stress and keep the brain sharp into old age.
-
Maintain a healthy weight
Keep your Maine Coon in the 4–9 kg range. Even modest weight loss in overweight pets significantly improves longevity.
