How Big Do Maine Coon Cats Get? A Growth Guide

By Royal Maine Coon Kittens · Published 2023-10-15

Maine Coons are known as gentle giants. Learn exactly how big you can expect your kitten to grow, when they stop growing, and how to support their healthy development.

The Gentle Giants of the Cat World

Maine Coons are famously one of the largest domesticated cat breeds. While a typical domestic cat might weigh 8-10 pounds, a healthy Maine Coon can easily double that.

Average Weights and Sizes

Male Maine Coons typically weigh between 15 and 25 pounds (6.8 - 11.3 kg), while females are slightly smaller, usually weighing between 10 and 15 pounds (4.5 - 6.8 kg). In terms of length, they can stretch up to 40 inches from nose to tail tip!

The Growth Timeline

Unlike most cat breeds that reach their full size by one year of age, Maine Coons are slow growers. They typically don't reach their full physical maturity until they are 3 to 5 years old. This means you will have a growing kitten on your hands for a very long time!

Diet and Nutrition for Big Cats

Because of their prolonged growth period, it is essential to feed them high-quality kitten food longer than you would a normal cat. Always consult your vet, but many breeders recommend keeping Maine Coons on kitten-specific formulas for up to 18-24 months to support their bone and muscle development.
