How to Help Your Maine Coon Live Longer
-
Keep them indoors
Indoor cats live on average 10–15 years longer than outdoor cats due to reduced exposure to disease, predators, and accidents.
-
Feed the right amount
Maine Coons need 220–380 kcal/day. Obesity is the #1 preventable cause of shortened feline lifespan.
-
Daily play
30 minutes of interactive play daily supports healthy weight, mental stimulation, and cardiovascular health.
-
Dental care
Dental disease affects over 70% of cats by age 3. Weekly brushing or dental treats prevent bacteria reaching vital organs.
-
Annual vet visits
Cats hide illness well. Annual exams catch problems before they become serious. Senior cats benefit from twice-yearly check-ups.
-
Keep vaccinations current
Core vaccines protect against diseases that significantly shorten feline lifespans. Ask your vet about the right schedule.
