To get a good understanding of how big can a Maine Coon cat get, take a look at our table below which details average Maine Coon adult sizes. Whilst this cat breed does vary in size, it’s clear to see that even the smallest adult Maine Coon will be larger than the average sized cat.

Maine Coon SizeMaleFemale
Weight (lbs)15 – 258 – 12
Weight (kg)6.8 – 11.33.6 – 5.4
Height (inches)10 – 168 – 14

Additionally, both cats have the potential of growing up to 40 inches in length, which makes for a seriously long cat.

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

As one of the oldest natural cat breeds in America, this popular cats history will likely remain shrouded in mystery and intrigue, forever. Whilst many have tried to explain why the Maine Coon cat is genetically so much bigger than a normal cat, ultimately no one has the answer to this long-standing puzzle because without categorical evidence, the Maine Coons lineage remains a mystery.

Folklore myths claim to hold the answer to a Maine Coons size. However, whilst many stories have been linked to this large cat breed over the years, only three myths have really stood the test of time. Could these myths hold the key to this mysterious breed? … You decide.

The three key folklore myths relate to:

  1. Mating between raccoon and semi-wild domestic cat
  2. Maine Coons descend from Marie Antoinette’s Turkish Angora cats
  3. Vikings introduced long haired cats to Maine, United States

I shall briefly cover each of these myths, so that you can assess for yourself whether they can account for why the Maine Coon cat is so much larger than ‘normal’ cat breeds.

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, therefore producing the Maine Coon cat breed that we know and love today. As bizarre as this folklore myth might sound, some individuals still believe the Maine Coon cats is related to the raccoon.

So why did the myth become popular? The table below details the factors that were given in evidence to support the theory that raccoons are biologically linked to Maine Coon cats.

EvidenceDescription
Bushy TailBoth animals have a bushy tail
Black Ring On TailThe raccoon and Maine Coon each have a black ring around the end of their tails
Visually SimilarThese species are considered visually similar
Love WaterBoth animals are fascinated with water
Semi-Prehensile PawsThe Maine Coon and raccoon have semi-prehensile paws that they use to help grasp food more easily
SizeThe raccoon and Maine Coon are of a similar size
Great ClimbersThese species are well known for their superb climbing abilities

Scientists have discounted this particular myth, despite its widespread popularity, claiming it is biologically impossible.

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 would give the Maine Coon cat breed a truly regal history, if it were true. But is it?

According to this folklore the former Queen of France, Marie Antoinette, made a desperate attempt to flee France during the French Revolution. Legend has it that she arranged with Captain Samuel Clough to be a stowaway on his ship, headed for the United States. She is thought to have loved her six Turkish Angora cats so much though, that she was unable to leave France without them. The Captain thus 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 honoured his bargain though, and made sure that the former Queens treasured cats made it to their final destination of Wiscasset, Maine safety.

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 we know and love today.

3. Vikings Introduced Long Haired Cats

The final and potentially most likely of the three legends relates to the Vikings, who spent much of their time at sea. It is thought that they 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 Stated, thus producing the Maine Coon cat breed of today.

This legend has stood the test of time because the Maine Coon and Norwegian Forest Cat have always been considered very similar. Take a look at my article “Maine Coon Vs Norwegian Forest Cat: Key Differences” article, to see why.

Maine Coon Growth Spurts

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

a) Slow Growth

Maine Coon cats are known for being extremely slow growing creatures, not reaching their full adult size until ages 3 – 5 years. This is unique in the cat world since the majority of ‘normal’ cats reach full size by 2 years old.

Unfortunately, because this is not a very well known fact, owners often start overfeeding their Maine Coon around the 2 year mark. Whilst this is done with good intention, since owners become concerned that their cat hasn’t reached their anticipated proportions, this regrettably leads to Maine Coon obesity.

b) Kitten Growth Spurts

Never underestimate the potential size of your Maine Coon kitten, since your cat will inevitably surprise you by their never ending growth. The majority of their growth spurts will take place during the first year of their life, but the growth process definitely doesn’t stop there. 

It’s not just their body that grows large either, it’s also their features i.e. ears, tail, paws. 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 overemphasised.

c) Estimating Future Size

One quick (yet non scientific) way of estimating the adult size of your Maine Coon kitten, is by looking at the size of their paws. If they are quite big paws, remember that a purebred Maine Coon will ultimately grow into a equally proportioned adult cat. Therefore, if the paws still look big as your cat ages, there is likely quite a bit more growth to be expected!

d) Maine Coon Growth Chart Table

For those of you wondering how big can a Maine Coon cat get, and when should you expect to see growth spurts, take a look at my table below for a rough idea:

Biggest Maine Coon

I originally thought my friend was pulling my leg when they told me about Stewie, the 48.5 inch long Maine Coon cat. I mean, can you even imagine how massive that cat must be?! So I checked ….

1. Stewie

The verdict is that this story is true! Check the 2010 Guinness World Records book out if you don’t believe me, since Stewie really did achieve the title for “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 also smashed the average Maine Coon size too, by weighing an incredible 33 lbs (15 kg)! 

It’s natural to assume that the cat grew immensely big as a result of owner intervention, however you would be wrong. In fact, the owner of Stewie clearly states on record that no special diet was followed at all. Instead, the reality is that their cat just never stopped growing, like they expected him too!

2. Ludo

Another Maine Coon trying 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 for “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), yet this cat is still not as long as Stewie!

Omar is thought to weigh 30.87lb (14kg), which is far more than the average Maine Coon cat that usually sits within the 8 – 25lb weight bracket.

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?
