How long do Maine Coons live?

With proper care, Maine Coons typically live 12-15 years. Some well-cared-for individuals may reach 16-18 years. Regular veterinary checkups, a quality diet, and proper exercise can help maximize their lifespan.

Are Maine Coons good with children and other pets?

What should I feed my Maine Coon?

Maine Coons need a high-protein diet with quality animal proteins as the first ingredients. Look for food specifically formulated for large breeds with added taurine for heart health. Wet food can help with hydration, and some owners supplement with raw or cooked meat.

How often should I groom my Maine Coon?

Maine Coons require regular grooming 2-3 times per week to prevent mats in their long fur. Daily brushing is ideal during shedding seasons (spring and fall). Pay special attention to their belly, tail, and behind the ears where mats commonly form.
