Our adult Maine Coons are very much what you would expect with this breed: an average of 18-25 pounds for full-grown, neuter males and 12-18 pounds for full-grown, spayed females. Size is prized in this breed, but in our opinion overall weight should not be the key attribute to evaluate when looking for a Maine Coon.
