When Does Maine Coon Stop Growing

Maine Coon cats are famed for their majestic look and friendly nature. These feline friends are a much-loved choice among many cat fans and owners. One query that often pops up is: when do Maine Coons stop growing? Let’s explore the exciting world of these magnificent cats and uncover some interesting facts.

Maine Coon kittens are born small and delicate, just like any other cat. However, what sets them apart is their remarkable growth rate. Different from most domestic cats, Maine Coons take longer to reach their full size. On average, it takes these gentle giants three to five years to fully mature. During this period, they experience amazing physical changes that make them one of the greatest domestic cat breeds in the world.

As Maine Coons keep on growing, their size becomes more visible with each passing month. Their bodies form strong muscles and bones, allowing them to attain an impressive stature. Moreover, their thick fur adds to their whole magnificence, making them even more attractive in appearance.

Interestingly, male Maine Coons are usually bigger than females. While females can weigh around 8 to 12 pounds on average, males can reach weights of 13 to 18 pounds or more! This huge size difference between genders makes for an intriguing characteristic of this breed.

In accordance with the American Association of Feline Practitioners (AAFP), Maine Coon cats are considered “slow growers” due to their genetic makeup. This slow growth allows for a gradual development, resulting in their unique size and sturdy body.
