A healthy adult male Maine Coon weighs 13 to 18 pounds, while females weigh 8 to 12 pounds. Kittens gain about 1 pound per month until 12 months, then fill out until 3 to 5 years old. Use our weight chart to track your cat’s growth.
Why Maine Coons Are Larger Than Other Cats
Maine Coon cats are one of the largest domesticated cat breeds. Their size is due to genetics and slow maturation. Unlike other cats that reach full size by 12 to 18 months, Maine Coons continue growing until 3 to 5 years old. This prolonged growth period allows them to achieve their impressive stature.
