Maine Coon cats are considered one of the largest domesticated breeds due to various factors. The factors include genetic roles influenced by Pkd1 and Mc1r type genes or their northern heritage, natural habitat, etc.
Furthermore, their diet, rich in proteins and fats, has facilitated their robust development. Their larger paw size and strong musculoskeletal system have aided in adapting to their native habitat.
Knowing these influences can help you understand the interesting reasons behind the Maine Coon’s large size. To know more details on Why Are Maine Coon Cats So Big including Are all they big, how big they are at different ages, When a Maine Coon is big for the wrong reason, etc.
Why Are Maine Coon Cats So Big?
Maine Coon cats are known for their large size and friendliness. Many things, like genes and where they live, make them large. Let’s explore why they’re one of the biggest pet cats.
1. Genetic Influences
The impressive size of Maine Coons is linked to certain genes like Pkd1 and Mc1r.
The Pkd1 gene normally regulates kidney growth. It also affects body size when it undergoes mutations.
Similarly, changes in the Mc1r gene, which controls coat color, might influence melanin production and, thus, body size.
These genetic factors are combined with breeding practices, diet, and environment. Collectively, they can contribute to a significant increase in size, with some individuals reaching weights of over 20 pounds.
2. Natural Habitat
The natural habitat of Maine Coons, like cold climates and ample prey, affects their large size. In the wild, they eat a lot of protein and fat from rodents and birds.
This diet, plus needing to stay warm in the cold origin area, helps them grow big. Also, being active outdoors helps build muscle.
All these things add up to the Maine Coon breed usually being quite large, with males weighing 13 to 18 pounds (5.9 to 8.2 kilograms) and females 8 to 12 pounds (3.6 to 5.4 kilograms).
3. Slow Growth Rate
Maine Coons grow slowly compared to other cats, continuing to get bigger until they’re around 3 or 4 years old. This gradual growth over a longer period lets them become larger than many other breeds. So, their slow and steady growth contributes to their impressive size.
4. Evolutionary Advantage
Evolutionary advantage means having traits that help an animal survive and reproduce better in its environment.
For Maine Coon cats, this could mean being larger and having thicker fur. This feature might help them hunt effectively and stay warm in harsh winters.
Moreover, this might give them a better chance of thriving and passing on their genes to the next generation. That’s maybe why today’s Maine coon breeds big size due to their ancient parents.
5. Selective Breeding
Over time, breeders deliberately selected larger Maine Coons for breeding, leading to the development of a distinctive breed with an average weight range of 13 to 18 pounds, while exceptional individuals can reach weights exceeding 20 pounds.
6. Nutrition and Diet
Maine Coons’ diet is naturally high in protein and fat. This facilitates their robust growth. Their dietary habits, including consuming meat-based products, contribute to their average size range of 10 to 16 inches in height and 13 to 18 pounds in weight.
7. Environmental Adaptation
Maine Coons are known for their large size. They have evolved to thrive in cold climates like Maine. Their big build helps them stay warm in chilly environments.
Research indicates that Maine Coons typically weigh between 10 to 25 pounds, with some exceptional cats weighing up to 30 pounds.
Their bigger paws and strong bones give them better balance and movement, especially in snowy or rough areas.
These adaptations have helped Maine Coons succeed in their environment. This may make them bigger and better equipped for survival.
8. Longevity
Maine Coons have a longer lifespan compared to many other domestic cat breeds. This allows them more time to achieve their maximum size potential.
They have ample time for significant growth and development, with a life expectancy of 12 to 15 years.
9. Intact Natural Behaviors
Preserving their natural behaviors, including active hunting and exploration, ensures that Maine Coons remain physically engaged, contributing to their muscular build and healthy growth throughout their lifespans.
10. Hybridization
Some historical theories propose that Maine Coons’ substantial size might be a result of interbreeding with other larger domestic or wild cat species. This potentially influences their genetic makeup and physical characteristics over generations.
11. Body Structure
Maine Coons’ solid bone structure and muscular build are key to their size. Their strong bones and well-developed muscles support their large frame, allowing them to carry their weight effectively. This robust physique enables them to move easily and improves their appearance.

- Runts of the litter, born smaller than their siblings, might not reach typical size.
- Malnutrition or poor health can also stunt growth.
- Research indicates that around 1 in 4 Maine Coons may not meet the typical weight range due to these factors.
How Big Was the Largest Maine Coon on Record?
Stewie, a Maine Coon from Reno, Nevada, holds the title of the largest Maine Coon cat ever, measuring a remarkable 48.5 inches in length, significantly surpassing the typical 19-30 inches for male Maine Coons.
