1. Stewie

Stewie still holds the record for the largest Maine Coon ever recorded!

He measured a total of 48.5 inches.

Stewie was a loving, sweet cat who spent his free time volunteering as a therapy cat at a local senior center.

His community was devastated when, on February 4th, 2013, Stewie passed away at age 8.

Even though he has since passed, no cat has broken his record since.

Barivel is the largest domestic cat alive today.

After Stewie passed, the title for largest living cat passed to Barivel, who measures a total of 47.2 inches long!

Today, he lives with his loving owners in Italy and has thousands of adoring fans on his Instagram account.

Sadly, he died in June of 2019.

4. Omar

Omar is another incredible Maine Coon who resides in Australia.

5. Cygnus

Cygnus was immortalized in the Guinness Book of World Records for his incredible tail, which measured a total of 17.58 inches.

How Big Are Giant Maine Coon Cats?

  • Weight: 8 – 25 lbs
  • Length: 19 – 40 inches
  • Height: 8 – 16 inches

The largest recorded Maine Coon was Stewie, who measured a total length of 48.5 inches!

Of course, it was pure luck that Stewie’s owners ended up with such a massive cat, but who knows? You might just get lucky enough to get a Maine Coon that is just as big!

Why Are Maine Coon Cats So Large?

If you want to know why are Maine Coons so big, here are three reasons why these cats are so massive:

1. Enormous Ancestry

Genetic testing shows that the closest relative to the Maine Coon is the Norwegian Forest Cat.

These cats were once kept by Vikings, and it is believed they were brought by ship to northeastern America sometime before the 1800s.

Maine Coon cats were already quite large, but a combination of natural and intentional selection has made them even bigger.

2. Natural Selection

Natural selection means that animals with advantageous traits are more likely to survive and bear offspring than animals without those traits.

The Maine Coon originated in the state of Maine, where it is believed Norwegian Forest Cats mated with local domestic and feral cats until the Maine Coon breed was developed.

The harsh, snowy climate meant that larger, more muscular cats with wide paws were better able to travel through the snow and successfully kill prey.

3. Intentional Selection

In the mid-1800s, sailors and farmers took an interest in these enormous cats, which often had wide, polydactyl paws.

Their paws allowed them to better grip mice and other pests, making them more proficient hunters than other cats in the area.

Farmers and sailors were more likely to keep Maine Coons than other cats and preferred cats with bigger paws.

Today, large Maine Coons are more popular than ones of average size, which means the breed will likely only get larger (source 1).

What Cat Is Bigger Than A Maine Coon

While Ragdolls, Savannahs, Siberians, and Norwegian Forest Cats are some of the largest cat breeds out there, there are no domesticated cat breeds bigger than the Maine Coon.

In fact, the Maine Coon even rivals certain wildcats in size!

For example, bobcats typically weigh between 13 and 30 pounds and measure between 30 and 50 inches long.

While bobcats are usually a bit taller than Maine Coons, standing about 21 inches tall, there are many Maine Coons that weigh much more than the average bobcat! (source 1).

Maine Coon Size Comparison To Dog

While the largest cat breed weighs about 8 to 25 pounds, the smallest cat breed weighs just about 5 pounds!

While this may seem like a drastic difference, it is nothing compared to the diversity of dogs.

Even though both dogs and cats were domesticated from just one species, why is it that dogs vary so much in shape and size than cats?

After all, while the smallest dog breed weighs just a pound, the largest dog can weigh well over 150 pounds!

The reasoning for this comes down to how and why humans domesticated cats and dogs in the first place.

Most cat breeds are pretty similar in size and shape because, historically, their only job has been to hunt pests.

Furthermore, cat domestication was a more passive process than the domestication of dogs.

Cats incidentally began hanging around humans once they began storing grain, which attracted mice.

Humans kept these cats around since they were so good at hunting pests, but they did not make an effort to change them.

After all, the size and shape of a cat does not really affect its ability to hunt!

Dogs, meanwhile, have been domesticated to perform all sorts of jobs from guarding to hunting.

The tiniest of dogs were kept as companions.

The long, skinny body of a dachshund was perfect for hunting otters, badgers, and other tunnel-dwelling creatures.

The enormous Great Pyrenees were bred to keep wolves from stealing sheep.

Today, cats may not vary much in size, but perhaps one day this will change.

After all, the Maine Coon has skyrocketed in popularity due to its size, and it is possible that responsible breeders might be able to produce Maine Coons that are bigger than small and medium dogs! (source 1,2,3).

What Makes A Maine Coon Cat Different?

The most obvious difference between Maine Coons and regular cats is their impressive size.

However, there are many other behavioral traits that separate Maine Coons from normal cats, as well.

Here are some examples:


Everybody knows that most cats meow, but the Maine Coon actually has a soft, distinctive voice that is completely different from most cats.

Instead of meowing, they usually:

  • Squeak
  • Chirp
  • Trill

Maine Coons usually only vocalize if they want something such as attention or playtime, but they occasionally like to have little “chats” with their owners for fun, too.

Doglike Personality

Maine Coons are often called the dogs of the cat world because of their intelligence, trainability, and ability to learn tricks or how to play fetch.

Maine Coons are also incredibly loyal and often follow their owners around the house.

Fondness For Water

It is no secret that most cats hate water, but did you know that many Maine Coons actually love to play in water?

This can likely be attributed to their snowy origins and semi-water-repellant fur.

Lots of Maine Coons love to hang out by the sink or tub, and may even learn to turn on faucets!


Many people know that Maine Coons have much larger, wider paws than the average cat.

Maine Coons are also more likely to be polydactyl, meaning they are more likely to have extra toes. Read more about the polydactyl Maine Coon cat, here.

Another unique feature of Maine Coons is that they often use their paws like hands!

Many Maine Coons dip their paws into their food or water bowls which, while messy, is also pretty adorable.

Some Maine Coons even learn how to open doors!


Despite their size and wild looks, Maine Coons are actually one of the gentlest, most patient cat breeds out there.

They get along famously well with kids, and will even tolerate playing dress-up or tea party! Is dressing up a cat cruel though? Find out about the dangers of dressing a cat, here.

They are also great if you already have pets, as Maine Coons love to make friends with just about any animal.


Many people want to know how big are Maine Coon cats, but when they see pictures, they cannot help but wonder, are Maine Coons really that big?

Even though some owners use Photoshop or forced perspective to make their cats look bigger than they are, Maine Coons are significantly bigger than the average cat.

So, how large do Maine Coon cats get?

On average, they weigh between 8 and 25 pounds and measure 19 to 40 inches long and 8 to 16 inches tall, making them the largest domesticated cat breed in the entire world.
