How Big is a Full Grown Maine Coon?

Full-sized Maine Coons are some of the most prominent house cats in the world. Maine Coon cats will weigh between 12 to 22 pounds when full grown. This makes a full grown Maine Coon the largest domestic cat.

Maine Coon size will vary depending on age and sex, with adult males being the largest. Still, all Maine Coon cats are enormous.

How Big is a Female Maine Coon?

The average adult female Maine Coon is between 12 to 15 pounds. Female Maine Coons are larger than most domestic cats, regardless of whether they are male or female. Female Maine Coons use their size to their advantage when hunting.

On The International Cat Association’s breed page, they point out that a female Maine Coon is still larger than the average cat. For comparison, most cats weigh under 10 pounds.

How Big is a Male Maine Coon?

The average adult male Maine Coon weighs between 18 to 22 pounds. This is much larger than other cats and can often be a source of shock for people comparing them to other cats for the first time. Put simply, a full-sized Maine Coon will almost always be the largest cat in the room.

Both of the weight ranges listed here are for healthy cats; while larger Maine Coons certainly exist, they usually are either outliers or overweight. In addition, their fur is thick and heavy and can contribute significantly to their look, making them appear even more prominent than they are.

As expected, Maine Coon cats go through a growth period similar to other cats, although they often start larger than usual either way. 

How Quickly do Maine Coons Grow?

Maine Coons grow slower than most other domestic cat breeds. A Maine Coon will likely continue to grow until it is 4 years old. Maine Coons are large cats that use their size to their advantage while hunting rodents.

Will All Maine Coons Grow Big?

Yes, all Maine Coons will grow big unless there is a genetic abnormality. Many of the critical factors that play into a Maine Coon’s growth appear during their young years as they are actively growing. While some elements such as sex and heritage are determined at birth, other elements like nutrition and neutering or spaying begin also play a role.

At What Age Are Maine Coons Fully Grown?

Maine Coons reach full maturity around the age of 4. Until that point, your Maine Coon will continue to grow and may already be quite large well before then. At 4 years old, Maine Coons are physically imposing standing up near most domestic cats.

During this period, their nutrition can play a significant role in their size. Proper nutrition and feeding habits will help them thrive rather than simply getting fat. Also, it will help with the health of their coat, making it grow longer and thicker, contributing to their perceived size.

Even after their growth period, it is essential to provide a Maine Coon, like any other cat, with proper nutritional value.

Should I Neuter My Male Maine Coon?

Yes, you should neuter your male Maine Coon. Many people believe Maine Coons grow larger if they are not spayed or neutered, but there is no science for support. Unless you plan on breeding the animal further, it is best to fix your pets to make care easier and prevent unwanted pregnancies.

Litter Box:  I started out with normal, traditional litter boxes for my cat.  Then, I tried this automatic litter box on Amazon (affiliate link), which helped reduce the litter upkeep.  Finally, I am now a believer in the Litter-Robot 3 Connect on Amazon (affiliate link).  This robotic litter box is not for everyone based on the price tag, but for me the benefits (very little upkeep, works efficiently, clean, mobile app) far outweighed the cost.

Cat Tree:  I have purchased a couple of this Amazon Basics Cat Tree on Amazon (affiliate link).  My cat spends a lot of time on and around this cat tree, which I position near my sofa.  She uses the scratching posts on this cat tree multiple times a day, which means she is not scratching the sofa instead.

Cat Water Fountain:  I love this cat water fountain on Amazon (affiliate link).  There are three main benefits to having a water fountain like this for your cat.  The first benefit is that it keeps water running so that your cat doesn’t need to drink still water.  The second benefit is that it filters the water.  The third benefit is that it will keep your cat hydrated!

Are Savannah Cats Well Behaved?

Savannah cats are usually well behaved even though they have wild cat genes in their genetics. Savannah cats are often compared to dogs because they are loyal to their owners and follow them around. Savannah cats will learn tricks that they are taught by their owners, such as fetch.

The Savannah cat is a hybrid, meaning that they mix a wild cat and a domestic. In addition, Savannah cats have the African Serval, a wild cat that looks highly similar to a recent ancestor. This contributes to their strong hunting instincts and characteristics.

While Savannahs can be friendly and sociable, Maine Coons tend to be a better choice for households with other pets and children. This is especially true if the Savannah has not been socialized properly as a kitten; their strong hunting instincts may cause them to attack, similar to a wild cat.

In comparison, Maine Coons tend to have relaxed and playful temperaments that make them easier for large families.

Is Savannah Cat a Hybrid?

Yes, Savannah cats are hybrids between a Serval and a domestic cat. Thanks to their hybrid status, Savannah cats are even banned in Hawaii, Massachusetts, and Georgia. Still, they can be fantastic cats, even for families – they are just likely to require more work with socializing and a closer eye than a Maine Coon would.

  • Following people around
  • Waiting near doors
  • Sitting near you

They are unlikely to become aggressive or scratch at people unless particularly annoyed, as with most cats. Their larger size does not mean that Maine Coons are more dangerous or harmful than any other house cat. There is no reason to believe that a scratch will worsen from a Maine Coon than any other smaller house cat.

Are Maine Coon Cats Friendly with Children?

Maine Coon cats are friendly with children. Maine Coon cats have a delightful temperament and easy attitude, that makes them better for children and other pets to be around than other cats who may get frustrated more easily. Especially as kittens, Maine Coons enjoy playing and “helping” with most activities.
