Maine Coon Kitten Size

Since Maine Coon cats grow into large cats, you are likely already wondering if Maine Coon kittens are bigger than the average kitten too?

The answer is yes, you can expect the Maine Coon kitten size to be slightly bigger than a normal cat.

If you take a look at our Maine Coon kitten growth chart, you can see that the average Maine Coon kitten size is as follows:

  • Newborn: 0.2 – 0.3 lbs
  • 1 Week: 0.6 – 0.9 lbs
  • 1 Month: 1.2 – 1.6 lbs
  • 6 Months: 6 – 10 lbs

The Maine Coon kitten’s weights in lbs contrast with those of a normal kitten that weighs roughly the same amount as their month of age.

For example, a 1-month-old normal kitten will weigh roughly 1 lb, and a 6-month-old normal kitten will weigh approximately 6 lbs.

By comparison, the 1-month-old Maine Coon kitten weighs approximately 1.2-1.6 lbs, therefore slightly heavier than a normal kitten.

At 6 months of age, the gap between the Maine Coon kitten size vs Normal kitten size starts to become more apparent.

This is clear since a normal kitten weighs roughly 6 lbs at 6 months old, whereas a Maine Coon kitten’s weight can range anywhere between 6-10 lbs at this age.

Male Vs Female Maine Coon Size

Maine Coons cats are a large muscular cat breed, with a very sociable and gentle nature.

The male of the species will ultimately grow physically bigger than its female counterparts, however, in terms of height male and female full-size Maine Coons are 10-16 inches high.

Can Female Maine Coons Grow Bigger?

You might have already noticed that there is a cross-over in the male vs female Maine Coon size.

It is therefore possible for a large female Maine Coon cat to grow bigger than a small male Maine Coon cat.

Thus, a female Maine Coon kitten may grow larger than a male Maine Coon kitten!

Which Gender Is Best?

Maine Coon sizing is not the only factor to consider when selecting between a male or female Maine Coon kitten.

Maine Coon Size Compared To Normal Cat

If you are wondering how big a Maine Coon cat will grow compared to a normal cat, take a look at the Maine Coon vs regular cat size graphic below:

Here is a Maine Coon size comparison to normal cat breeds (full-size dimensions):


Normal cats reach 9-10 inches tall, whereas Maine Coons grow to 10-16 inches tall.

Full-size Maine Coons grow between 19-40 inches long.


Normal cats weigh 4-5 kg, whereas the Maine Coon weighs 3.6-11.3kg (8 – 25 lbs).

If we look at the Maine Coon compared to normal cat breeds, yes, there is a small level of cross-over in terms of cat weight.

However, generally speaking, Maine Coons grow substantially longer and taller than most regular cats.

Maine Coon Vs Turkish Angora Weight

If we compare the Maine Coon size vs Turkish Angora size, we immediately see the Turkish Angora males are far smaller than the male Maine Coon since they only weigh between 7-10 lbs (3.5 – 5kg).

The female Turkish Angora is also smaller than the female Maine Coon size, weighing just 5-8 lbs (2.5-4kg) (source 1).

Maine Coon Vs Ocicat Size

Another example of how the Maine Coon size compares to other cats is the comparison of the Maine Coon vs Ocicat.

The Ocicat is thought to be a semi-wild cat breed, but has it the potential to grow as big as the average adult Maine Coon? Let’s see!

In terms of weight, the Ocicat is smaller than the Maine Coon size, since they weigh between 6-15 lbs, whereas a Maine Coon ranges from 8 – 25 lbs!

The Maine Coon is slightly taller than the Ocicat, sitting at 10-16 inches tall, compared to the Ocicat’s 9 – 11 inches height range (source 1).

Why Are Maine Coon Cats So Big Compared To Normal Cats?

As one of the oldest natural cat breeds in America, this popular cat’s history will likely remain shrouded in mystery and intrigue, forever.

Many cat specialists have tried to explain why the Maine Coon cat is genetically so much bigger than a normal cat.

Slow Growth

Some cat fanatics claim the Maine Coons slow growing bodies have helped them develop stronger more muscular frames.

Whilst they might grow quickly as kittens, their bodies then slow the growth rate to enable their skeleton and muscles to continue growing larger than normal cats.


Other cat breed specialists point to the Maine Coon cat’s genetics as the key reason why this breed grows so big.


The Maine Coon’s nutritional diet also plays a big role in the Maine Coons large proportions.

These obligate carnivores require a diet high in protein to help their muscles grow big and strong.

Maine Coon cats that do not consume enough protein often end up smaller than average in terms of this cat breed’s average dimensions.

If you are wondering if it’s possible for a Maine Coon cat to be small, read this guide.

Natural Breeding

Others have drawn attention to the fact that only the biggest Maine Coons survived the cold frigid winters of Maine.

This cat breed evolved to survive the harsh climate of the North Eastern winters.

Only the strongest cats of the breed survived, and when these cats bred they passed on their stronger more resilient genetics and giant Maine Coon size to their kittens!

Maine Coon Origin

Ultimately no one has the answer to the long-standing puzzle about where the Maine Coon originates.

However, if you believe in folklore keep reading to discover the myths claiming to hold the answer to the Maine Coons giant size!

Many stories have been linked to this large cat breed over the years, however, only the following three myths have stood the test of time:

  1. A raccoon and semi-wild domestic cat mated
  2. Descendents of Marie Antoinette’s Turkish Angora cats
  3. Vikings introduced long-haired cats to Maine

Let’s take a closer look at these Maine Coon origin theories:

1. Raccoon And Semi-Wild Domestic Cat

The theory of this myth is that a more tame raccoon once mated with a semi-wild domestic cat, thereby producing the Maine Coon cat breed that we know and love today.

As bizarre as this folklore myth might sound, people still believe Maine Coons are related to the raccoon!

However, scientists have now discounted this particular myth, despite its widespread popularity, claiming it to be biologically impossible.

The table below highlights why the myth has been so popular over the years since it draws attention to the many physical similarities between raccoons and Maine Coons:

Bushy TailBoth animals have a bushy tail
Black Ring On
The raccoon and Maine Coon
each has a black ring around
the end of their tails

2. Descendents Of Marie Antoinette’s Turkish Angora Cats

The love story between Marie Antoinette and her six Turkish Angora cats is a powerful folklore myth that gives the Maine Coon cat breed a truly regal history if it’s true.

Legend has it that the former Queen of France, Marie Antoinette, made a desperate attempt to flee France during the French Revolution.

She arranged with Captain Samuel Clough to be a stowaway on his ship, headed for the United States.

Her love for her six Turkish Angora cats was so much though, that she was unable to leave France without them. So the Captain agreed the cats could be loaded onto his ship, as well.

Sadly, despite her best efforts, Marie Antoinette was captured and executed in 1793.

It is thought that Captain Samuel Clough honored his agreement with the former queen, making sure the treasured cats made it to their final destination of Wiscasset, Maine safely.

Once on dry land, these cats were set free and are thought to have mated with the short-haired domestic cats already residing in Maine, creating the Maine Coon cat breed.

3. Vikings Introduced Long-Haired Cats

The most likely of the three legends relate to the Vikings, who spent much of their time at sea.

It is thought the Vikings kept Norwegian Forest Cats on their ships to keep their ship mouse population at bay.

According to this folklore, one of these long-haired cats is thought to have mated with a short-haired domestic cat already residing in Maine, United States, thus producing the Maine Coon cat breed.

This legend is still believed today since there are many physical similarities between the Maine Coon and Norwegian Forest Cat breeds.

Take a look at my article comparing the Maine Coon Vs Norwegian Forest Cat to discover just how bizarrely similar these two massive cat breeds are.

Maine Coon Growth Spurts

Just like other cats, the Maine Coon will go through a number of growth spurts before reaching its ultimate adult size.

Take a look at the Maine Coon growth chart table below to see the key Maine Coon growth stages:

Kitten Growth Spurts

Maine Coon kittens will experience the majority of their growth spurts during the first year of their life, however, the growth process definitely does not stop there!

The Maine Coon kitten’s body, including its ears, tail, paws, etc, will also grow big.

Take note of these features whilst your cat is still a kitten since these aspects will also slowly grow, in line with your Maine Coons overall body size.

Ultimately, a purebred Maine Coon cat is said to be completely in proportion, with no part of their body being overemphasized.

Take a look at this table showing how big a Maine Coon kitten grows, by age.

Slow Growth

Maine Coon cats are known for being extremely slow-growing creatures, not reaching their full adult size until between 3 – 5 years of age.

This is unique in the cat world since normal cats usually reach full size by 2 years old.

The Maine Coons slow growth rate is not a well-known fact though, which has resulted in many owners overfeeding their Maine Coon at 2 years old, concerned their Maine Coon is too small.

Whilst this is done with good intention since owners become concerned that their cat has not reached their anticipated proportions, this regrettably leads to Maine Coon obesity.

Learn more about Maine Coon obesity, in this article.

Estimating Future Size

One non-scientific way of estimating the adult size of your Maine Coon kitten is to look at the size of their paws.

If your Maine Coon kitten has big paws it will likely grow into a giant Maine Coon cat, since full-sized purebred Maine Coons are equally proportioned cats.

Therefore, if the paws still look big versus your cat there likely still have more growth to do!

Biggest Maine Coon

The biggest Maine Coon cat in the world was a cat named Stewie who grew into a giant Maine Coon, reaching 48.5 inches in length!

Learn more about Stewie and other famous Maine Coon cats below:


According to the 2010 Guinness World Records book, Stewie holds the title of “the longest cat of his breed’, measuring an immense 48.5 inches in length (that’s 123.19 cm!).

His tail alone was thought to measure a whopping 16 inches!

This long cat was also a giant Maine Coon since he was bigger than the average Maine Coon size, weighing in at an incredible 33 lbs (15 kg)!

Many people questioned if Stewie had grown big due to his diet, or owner’s intervention.

Stewie’s owners confirmed that no special diet was followed. Instead, the reality is that their cat just never stopped growing!

2. Ludo

Another Maine Coon vying for the title of ‘longest cat of his breed’, is Ludo.

This cat has been measured at 46.58 inches (118.33 cm).

If Stewie’s length measurements are correct though, Ludo cannot win the title.

3. Omar

In 2017, the title of “longest cat of his breed” was challenged by a Maine Coon cat named ‘Omar’.

According to his owner, this large Maine Coon measures a staggering 120cm, from his nose to the end of his tail (source 1), yet this cat is still not as long as Stewie!

Omar weighs 30.87lb (14kg), which is far more than the average Maine Coon cat that weighs 8 – 25 lbs!

This Maine Coon has always been fussy with his food, and kangaroo is the only meat he will eat.

Could this Maine Coons unusual diet of raw kangaroo meat be held accountable for why he has grown so big?

What Does A Large Maine Coon Look Like?

I could try explaining what a large Maine Coon cat looks like, however, pictures are worth a thousand words.

So here is a Youtube video of a 4ft Maine Coon cat known as Samson. Credit for the Youtube video goes to a Youtube channel named ‘Beastly’

As one of the largest domesticated cats in existence, reaching up to 25 lbs in weight, it is safe to say that a full-grown Maine Coon will not fit in your handbag!

These large cats are best described as small dog-sized cats, with a corresponding dog-like personality to match.
