Maine Coon cats are widely known for their lust-worthy coats and large body size, which leaves many people wondering, do all Maine Coon cats get big?
This is a very critical question considering that the heritage of this regal cat breed is steeped in mystery.
Maine Coons are the largest domesticated cat breed, weighing between 8 – 25lbs. All purebreds are relatively large cats, however, an extra-large non-pedigree cat can be larger than a Maine Coon at the smaller end of the Maine Coon size spectrum. Small Maine Coon cats are often part or mixed breed.
If you have just purchased a Maine Coon cat or are planning to adopt one, it is natural to question how large your new feline will get.
Read on to discover more about the Maine Coon’s majestic size, the breed’s large physical proportions, and just how big Maine Coon cats can get.
Do All Maine Coon Cats Get Big
Also known as the American Longhair, Maine Coons are the largest domesticated cat breed in the world.
Many people love these large cats for their:
- Affectionate Behavior
- Easy-Going Manner
- Laid-Back Nature
They also have many traits and characteristics that set them apart from other cat breeds.
First-time owners considering whether to adopt or buy a Maine Coon cat may find it interesting to know that this regal breed of cat makes for one of the oldest and most popular natural breeds in North America.
Here are some key factors that have been linked to why Maine Coon cats grow so large:
Although it remains a mystery as to how these beloved cats came into being, Maine Coon cats are thought to be native to Maine, US, where they have been recognized as the official state cat since 1985.
Learn more about their fascinating history in my article.
Regardless of who their progenitors were and how they came to the state of Maine, these cats grew visually very big after developing long, shaggy fur to keep themselves warm during the cold winter climate of the Northeastern United States.
This resilient cat breed survived in the wild for many years before they were domesticated.
Those of you wondering why the Maine Coon cat is so big might also be interested to learn that many folks attribute their large size to this breed’s natural lineage as wildcats.
As domesticated cats, Maine Coons come in a range of sizes but tend to be reasonably larger than the average household cats that you meet.
Check out this size comparison guide to see just how much bigger the Maine Coon cat is compared to a ‘normal cat’. The diagram I have drawn will likely shock you!
2. Slow Growth Rate
The Maine Coon cat breed matures very slowly, allowing them to develop larger muscles and bone structures.
Although there is no guarantee that all Maine Coons cats will get big, they seem to be genetically predisposed to grow large, which means that they will naturally get big.
For those of you wondering how big can Maine Coons get, you should expect your Maine Coon to grow anywhere between:
- 19 – 40 inches long
- 8 – 16 inches tall
The average Maine Coon size/weight is a tremendous 8 to 25 lbs.
Comparing male vs. female Maine Coon sizes, the male Maine Coon cats tend to be larger than their female counterparts.
While both the male and female Maine Coon grow to a staggering length of 40 inches, the females usually reach:
- Length: 35 Inches
- Height: 8 – 14 Inches
These figures are relative to male Maine Coon cats that can stand at roughly 16 inches tall.
Females Maine Coons will therefore appear smaller than their male counterparts.
As for Maine Coon weight, female Maine Coon cats weigh 8 to 12 lbs on average, whereas their male counterpart’s average weight is a whopping 15 to 25 lbs!
From these averages, it is safe to say that male Maine Coon cats are the biggest.
If you are a first-time owner, keep in mind that Maine Coon cats are prone to obesity, meaning a heavier Maine Coon could be overweight. For this reason, ensure that you keep your Maine Coon within a healthy weight range, and feed them a nutritional balanced diet, such as this.
Finally, whilst knowing that Maine Coons cats are naturally big felines, it is worth noting that not all Maine Coons will get very big. Here’s why.
As such, you should not be worried if your Maine Coon cat doesn’t get as big as the average figures suggest. After all, there are many factors (these reasons) that can determine whether each individual Maine Coon cat will reach the large size the breed is known for.
If you have purchased a Maine Coon cat and are wondering how big your Maine Coon cat will get, the parents of your cat are probably the best gauge to determine this.
Regardless of what size your cat’s parents are though, there is no guarantee that a Maine Coon will grow big.
Why Are Maine Coons So Large?
Purebred Maine Coons cats are known for their large size.
For the unacquainted, Maine Coons make for the largest domesticated cat breed in the world.
However, with their lineage embroiled in mystery and intrigue, it is relatively difficult to determine exactly why this particular cat breed grows so big. As such, all answers to why Maine Coons are so big are educated guesswork.
Please also keep in mind that since there is so little known about the lineage of this regal cat breed, there is no straight answer as to why Maine Coons get as big as they do. All that is known is that purebred Maine Coons cats grow big.
From stories relating to their mysterious origins to science about the breed’s slow growth rate, here are the most likely reasons and factors contributing to the Maine Coon’s large size:
1. Growth Rate
Maine Coons are known to mature very slowly, reaching full-size between the ages of 3 -5 years.
The slow growth rate allows these cats to develop substantially larger muscles and a rigid bone structure, which in turn gives them a large stature.
While genetics alone cannot determine the size of a Maine Coon, they have a role to play in the overall size of your cat.
Along with a slow growth rate, inherited genetics can affect the length and height of your cat.
Generally, a Maine Coon kitten whose parents are significantly large will also likely grow too big.
If you fancy reading up on Maine Coon Genetics then give my article a quick peek.
3. Native Environment
It is hypothesized that Maine Coons are big because of their native environment.
These cats originated in Wiscasset, Maine, where they had to develop ways of surviving through the harshest winter climates.
Their large bodies are thought to have been key in helping them hold more body heat.
As domesticated cats, Maine Coons cats are often kept indoors, which can affect their growth.
Indoor Maine Coon cats do not get a lot of physical activity to shed excess pounds, which increases their chances of getting larger.
Maine Coon cats are known to have long, luscious, thick coats of fur.
Although their shaggy fur does not make them large, it can give an illusion that the Maine Coon is remarkably big.
These large cats also have a mane around their neck and chest, which adds to their large physical size.
For those of you wondering how much Maine Coons shed, here’s the reality.
Maine Coon cats are naturally large felines, but the food they eat can aid them to grow bigger.
While there is no scientific proof to back this assumption, cats that get a highly nutritious diet (like this) will likely grow to their full size.
Regarding feeding, keep in mind that Maine Coons are vulnerable to obesity, so be careful not to overfeed your cat.
How Long Does It Take For A Maine Coon Cat To Be Fully Grown?
Maine Coon cats are perhaps best known for their stature and weight.
Considering that they retain their childishness and playfulness throughout their lives, many people wonder how long it takes for a Maine Coon cat to mature?
Well, while most people are tempted to think that Maine Coons grow quickly to their large size, the truth is quite the opposite.
It might surprise you to learn that the Maine Coon cat breed is not considered fully grown until they reach between three to five years old.
To know if your Maine Coon is making any progress and probably get a picture of when your cat will stop growing, it is advisable that you use a Maine Coon growth chart.
Always keep in mind that Maine Coon growth can be somewhat unpredictable, and your cat may sometimes outgrow the Maine Coon size chart.
There are a lot of factors that go into the growth and development of Maine Coon cats. These factors can cause both Maine Coon growth spurts or could adversely stunt their growth, ultimately causing them to be undersized.
If you are new to the world of felines, it might be worth noting that neutered Maine Coon cats tend to stop growing a little earlier. Further, neutering increases the chances of gaining weight.
Whether or not your Maine Coon cat is neutered though, it will still grow very slowly.
Whilst this might put you off neutering your Maine Coon, it is always best to understand the full facts (pros and cons) of the process, and know when the best age to neuter a Maine Coon kitten is.
Maine Coon Kitten Size Chart
Male Maine Coon cats may reach close to their full weight at the age of one year. Even so, they will continue to grow for the next 2 to 4 years.
The table below shows a male Maine Coon kitten size chart:
|Newborn||0.2 – 0.4|
|2 Weeks||0.6 – 0.9|
|1 Month||1.3 – 1.8|
|3 Months||3 – 6|
|6 Months||8 – 11|
|9 Months||12 – 16|
|1 Year||13 – 20|
|1.5 Years||15 – 25|
Use the weight chart above to help you keep an eye on your Maine Coon cat’s growth rate.
The table below shows a female Maine Coon kitten size chart:
|Newborn||0.2 – 0.3|
|2 Weeks||0.6 – 0.9|
|1 Month||1.2 – 1.6|
|3 Months||3 – 5|
|6 Months||6 – 10|
|9 Months||9 – 11|
|1 Year||10 – I 14|
|1.5 Years||12 – 14|
Please keep in mind that every Maine Coon cat is different, which means that your cat may portray a slightly different growth rate than listed above.
All in all, as long as you have a purebred Maine Coon cat, expect growth spurts to take place within the first year, especially around weeks 32 to week 50.
Whether or not your Maine Coon exhibits a growth rate as listed in the ranges above, beware that growth rates are somewhat unpredictable, plus there is no single known way to predict the pattern of growth.
To develop a growth chart for your Maine Coon, get a suitable scale, like a functional postage scale, to measure their weight.
You will also need a measuring tape or something flexible and easy to use for measuring the cats:
Keep recording the data and compare the figures with the breed averages. The disparity should not be very huge. If it is, make sure you consult your preferred veterinarian to rule out any underlying issues.
Can Maine Coons Be Small?
While Maine Coon cats are a naturally large breed of cat, some Maine Coon cats can actually be small.
This should not be surprising, considering that there are a lot of factors that affect the growth and development of every animal.
If your Maine Coon cat weighs less than 8 lbs, you will likely ask yourself, why is my Maine Coon small?
There are many possible reasons why Maine Coon cats may not get as big as the breed is prized for.
If your Maine Coon is tiny and you cannot figure out the cause, make sure to consult your veterinarian immediately (source 1).
Whilst small Maine Coons are rare, they are not impossible. However, for the most part, small Maine Coon cats are usually considered to be either young Maine Coons or part Maine Coons.
If you have purchased a Maine Coon cat and it just doesn’t seem to be getting big, here are a few possible reasons behind your cat’s small stature that you might wish to consider:
Slow Growth Rate
If your Maine Coon cat still looks small a few years after you purchased or adopted it, it is probably not fully grown. Your cat therefore likely to still be growing.
Unlike many other domesticated cat breeds, the Maine Coon has a very slow growth, taking up to 5 years to fully mature.
That said, if your Maine Cooon cat is less than five years old, you need to give it more time before ruling out the feline as small.
The Cat Is A Hybrid
It is very uncommon for a mature purebred Maine Coon cat to weigh under 8 pounds.
Adult Maine Coon cats with a considerably small stature are more likely not to be purebred.
Even if your cat has predominant Maine Coon features, it might be a mixed breed.
Many factors can influence the size of a Maine Coon, and one such factor is their diet.
A Maine Coon diet should be high in protein with low carbohydrates.
Read this article of mine to get full details on the most suitable diet for this particular cat breed.
If you have confirmed you have a purebred Maine Coon cat and the feline does not get big, it might be lacking some important nutrients.
Owning a Maine Coon is a big responsibility, so make sure to keep an eye on everything relating to your cat’s health.
Underlying health issues might cause your Maine Coon cat to under-eat, ultimately impeding the feline’s growth.
If your Maine Coon is small and seems not to eat very much, consult your veterinarian for intervention.
These are the top 7 Maine Coon health problems to watch out for. Make sure you note down their signs and symptoms, to rule out any possible underlying health conditions.
Although rare, dwarfism can occur in Maine Coons.
It is a genetic mutation that causes some Maine Coons to be very small.
Dwarfism could be inherited from parents.
Hyperthyroidism is a serious health condition that can impede Maine Coon growth.
With hyperthyroidism, the Maine Coon’s thyroid secretes too much thyroxine, which increases its metabolism. This causes the cat to burn through calories much faster, which may lead to being underweight.
Ultimately, this will keep the cat from getting big.
Runt Of The Litter
Relative to their siblings, runts usually grow up to be small.
As such, if your Maine Coon was born a runt, it may never grow as big.
Although rare, this is a condition that causes circulatory problems in a cat, which may lead to growth problems.
Some parasites like worms can infect your Maine Coon cat at a very young age and cause the cat to become underweight.
Further, parasites can lead to the following issues:
- Loss of appetite
These are key contributors to unneeded weight loss.
Any underlying health issues can impede growth in Maine Coon cats, causing the infected cat to become unnaturally small.
Whether it is cancer, viral infection, bacterial infection, or any form of illness, if your cat has been sickly, especially at a young age, it may not grow as big.
Remember to keep on consulting your vet for intervention.
Top 7 Maine Coon cat health issues to be alert to.
Premature Separation From Mother
If a Maine Coon kitten is separated from its mother at a considerably young age, it will not receive the care and nutrients it requires, which can adversely affect its growth and development.
How To Make Your Maine Coon Big
Maine Coon cats are loved for their beautiful looks and large size.
As such many Maine Coon owners wish to make their cats bigger and healthier than the next.
If you have a Maine Coon cat that has not grown as big as you expected it to, you might be wondering how can I make my Maine Coon grow bigger?

That said, the only secret way to make your Maine Coon cat get bigger is by feeding it high-quality nutritious food.
Why not learn more about:
Along with feeding your Maine Coon cat, remember to regularly take the feline for health checks.
There is some conflicting evidence that neutering and spaying can help accelerate growth.
Regardless of what diet your Maine Coon cat gets, always keep in mind that there is no guaranteed formula for making a Maine Coon bigger.
These cats will genetically grow to what their genes command.
How To Tell If Your Maine Coon Will Be Big?
Maine Coons are genetically predisposed to get big.
If you are contemplating how to tell how big your Maine Coon cat will get, the simple answer is that there is no way to accurately predict the future size of your Maine Coon cat.
To get an idea of whether or not your Maine Coon will grow larger, keep checking your Maine Coon’s weight chart.
Below are a few things that could help owners tell if their Maine Coon will grow big, even when they are still kittens:
It is thought that Maine Coon kittens will grow into large cats if their parents were large unless the kitten in question is a runt.
Many people also say that you can tell if your Maine Coon cat will get big by looking at its back legs.
Although there is no scientific proof of this theory, it is generally thought that tall back legs indicate a big cat in the making.
If your Maine Coon kitten has big paws, you can expect it to grow to a massive size.
Kittens with large ears also tend to grow big.
Largest Maine Coon Cat On Record
The Maine Coon is the largest domesticated breed of cat, growing between 8 – 25 lbs in weight.
Not surprisingly though, some Maine Coons have beaten the known averages by growing extremely long and heavier than predicted.
Whilst it isn’t crystal clear as to why some Maine Coons outgrow the average Maine Coon size charts, one of the Maine Coons most known for doing so was Stewie.
Stewie exceeded the known average, growing to a staggering length of 48.5 inches!
Although Stewie died in 2013 from cancer, he will be remembered in the world of felines. Stewie holds the title for the longest Maine Coon cat ever.
As for weight, the biggest Maine Coon weight on record is 34 lbs.
This is the weight of Ludo, one of the largest Maine Coons in history.
Ludo was recognized as the longest Maine Coon after the passing of Stewie and before the title of the longest Maine Coons was snatched by Barivel.
Currently, Ludo is the heaviest Maine Coon on record.
Barivel is the longest Maine Coon alive.
Unfortunately, it is not clear how much Stewie weighed. After all, weight is no longer used to determine the largest felines.
Other big Maine Coon cats listed in the Guinness World Records include:
- Moonwalk Mognum
Do Maine Coon Mixes Get Big
A Maine Coon mix is a cat bred from a purebred Maine Coon and a different cat species.
In most cases, a Maine Coon mix will exhibit a larger percentage of Maine Coon characteristics than those of the other species.
A Maine Coon mix may grow big, though in some cases, not as big as the purebred Maine Coon.
For instance, a Maine coon/Ragdoll mix cat is bigger, while a Maine Coon/Siamese mix is smaller.
Generally, half-bred cats do not have 100% features like those of a purebred cat. Therefore, a Maine Coon mix will rarely be as heavy as a purebred Maine Coon.
Mixing cat breeds rely on the gene principle; where one gene will come from the father and another from the mother:
- Some physiological characteristics will come from the mother while others will come from the father.
- The dominant gene greatly determines the behavior and physical characteristics of the newborn kitten.
- A few characters will be developed from the recessive gene.
For Maine Coon mixes, the Maine Coon gene is in most cases the dominant gene, meaning the resultant offspring can get as big as the purebred Maine Coon cat.
