The Maine Coon Siamese Mix (What You Need To Know)

Not all Maine Coons are purebred cats.

Ragdoll and Persian mixes are quite common, but information tends to reflect the purebreds.

The Maine Coon has been bred, whether accidentally or deliberately, with many other breeds, including the Siamese.

As only 2% of Maine Coons are purebred, and the Maine Coon is a popular breed of cat, that’s a lot of mixed breeds out there.

The Siamese is probably the most instantly recognizable of the Asian cat breeds.

Many people love their looks, and you won’t be surprised to learn that they breed with Maine Coons.

What Is A Maine Coon Siamese Mix?

Any mixed breed kitten has parents from two separate breeds.

They form the majority of cats in the world.

A Maine Coon Siamese mix is specifically the producing of a kitten with one parent being a Maine Coon and the other a Siamese.

The parents don’t necessarily have to be purebreds themselves, which is why the world of mixed breeds kittens is somewhat murky.

The parents of a mixed breed will have predominant traits associated with a particular breed.

The newborn kitten will get traits from its parents, but the process is always unpredictable.

No one can really speculate accurately on what a mixed breed kitten will look like or act like based solely on the parents breed.

Breeders don’t normally specialize in mixed breed cats so the most likely source of a Maine Coon Siamese mix will be from a private seller.

Maine Coon vs Siamese Mix

The Maine Coon and Siamese obviously look different, but how similar are they in other key areas.

Let’s run through some of the characteristics of the purebreds.

The Maine Coon

One of the most distinct things about the Maine Coon is its physical presence.

Even a small Maine Coon will be bigger than most domestic cats.

Large Maine Coons, probably male, will get to small dog size quite easily, and weigh around 20 lbs.

They’re intelligent and are generally considered to be one of the best mousing breeds out there.

They can certainly survive in the wild or outdoors.

They have a muscular physique and a wedge shaped face with very, very, distinctive lynx like ears.

They have the nicknames of being a ‘gentle giant’ or ‘dogs of the cat world’ which sums up their personality.

They are social, affectionate, loyal, friendly and will follow you around the house without being underfoot.

They are quite talkative as well, as many Maine Coon owners will conform.

Myself included.

The Siamese

There are many new cat breeds in the world, but the Siamese is one of the oldest breeds known.

They originate from Siam, modern day Thailand, thus giving them a touch of the wise an exotic as well.

The Siamese is an elegant creamy white colored cat breed with some eye-catching colors for their eyes and coat patches.

There are actually two types of Siamese.

  • Show
  • Traditional

The show Siamese is the more striking of the two, which is a very picturesque cat breed, with well defined features that are quite striking.

The sparkling blue eyes give a very elegant look to a slim body type.

The traditional Siamese has a more rounded head with a slightly bigger build.

However, both these styles have the same personality.

Siamese cats are curious and intelligent, but both traits can mean a demanding cat.

Siamese are very people orientated cats and try to involve themselves in your life to keep an eye on what you’re doing.

They are also quite dog like occasionally, will play quite vociferously, and occasionally try the game of fetch.

They like being the center of attention.

They are also famous for being quite talkative and conversational

This is a beautiful and exotic cat breed with an attitude.

The Size Of The Maine Coon Siamese Mix?

If there’s one fact to know about Maine Coons it’s that they are a large breed of cat, holding the title of the largest domestic cat breed.

It’s nicknames the ‘gentle giant’ for a reason and will typically be anywhere between 48 to 100cm in length.

Alita, my female Maine Coon is small for the breed and she is 19 inches in length without the tail, which is 14 inches in length.

The range of heights for a Maine Coon will be between 10 to 16 inches with the weight range 3.6kg to 8kg (8 to 18lbs).

Females are smaller than males.

The first biggest difference between a Maine Coon and a Siamese is the size.

Siamese cats

This is a medium-size cat.

The Siamese has a typical height of around 8 to 10 inches, with a body length between 11 to 14 inches.

With a thin frame, the weight range for Siamese is between 8-10 lb (3.6-4.5 kg).

That’s about half the size of a reasonably big Maine Coon,

A Maine Coon Siamese mix will be quite a bit smaller than a Maine Coon purebred.

How big will be a matter of genetics and the dominant genes passed on, but an average of the two breeds is 11 to 13 inches in height, with a weight range of around 8 to 15 lbs.

How Will A Maine Coon Siamese Mix Grow?

The Maine Coon is one of the slowest maturing breeds in the cat world.

They will continue growing for several years, only stopping growing somewhere between 3 to 5 years after birth.

The Siamese cat matures fully before 2 years of age.

A medium guesstimate would be that a Maine Coon Siamese mix would fully mature and stop growing somewhere between 2 to 4 years old.

It may be up to the dominant genes within the kitten as to how it fully develops.

Are Maine Coon Siamese Mixes Rare?

Maine Coons mixed with Siamese are not common.

While not going as far as rare, they are not as common as Maine Coon Persian mixes, or Ragdoll mixes.

You will have to hunt around for this particular mix of breeds.

What’s The Diet For A Maine Coon Siamese Mix?

Maine Coons require very specific care and feeding guidelines.

They need a high protein diet.

As alluded to earlier, Maine Coons mature late so require a high protein diet to maintain their growth.

Animal meat products like chicken, turkey, duck, or fish based diets rather than grain based diets are preferable because of the higher protein content.

Therefore a Maine Coon Siamese mix should have a protein rich diet as well.

The Personality Of The Maine Coon Siamese Mix

The Maine Coon as well as its size is known for its laid back and gentle nature.

Due to this gentle nature, the breed is great for families with children.

Maine Coon Siamese mixes will arguably share common characteristics from their parent breeds.

The Maine Coon is known for –

  • Social
  • Affable
  • Gentle
  • Affectionate
  • Calm
  • Playful
  • Loyal
  • Talkative
  • Intelligent

The Siamese is known for –

  • Intelligent
  • Talkative
  • Sociable
  • Playful
  • Mischievous
  • Attention Seeking
  • Sporty
  • Not Being Left Alone
  • Agile
  • Affectionate

The lists are very similar in terms of attitude and temperament.

The Maine Coon Siamese mix will likely be affable, social, playful, and inquisitive.

What’s interesting to note is there is some significant overlap in personality.

Both pure breeds are talkative as well as communicative.

The Maine Coon and the Siamese are considered dog like, people orientated, as well as having a penchant for following you around.

It’s probably good odds that a mix of these two breeds will carry over these similar traits.

A mixed breed cat can get more dominant traits from one particular breed but where there is overlap it could be from either.

How Much Do Maine Coon Siamese Mixes Cost?

An authentic Maine Coon kitten will normally cost between $800 to $2000, depending on factors including age, health, color of fur, breeding status, or demand by the customer base.

For the same set of factors, a purebred Siamese kitten at 12 weeks will be in the range of $800 to $1500.

You might expect then that a Maine Coon Siamese mix would be in the $800 to $2000 range.

However, a Maine Coon Siamese mix does not mean both parents are purebreds.

A kitten from the mix of two breeds might have more ‘Siamese’ in their DNA but the Maine Coon traits might be more dominant.

The parents not being purebreds can mean the quantity of DNA from one particular breed can vary.

As they are rare(ish) the price for Maine Coon Siamese mixes will be slightly higher than a normal mixed breed cat which normally drives the price down a little.

Somewhere between $1000 to $1500 would be about right for this mixed breed.

What’s The Lifespan Of A Maine Coon Siamese Mix?

The lifespan depends upon a lot of factors, but a Maine Coon has a life expectancy between 12 to 15 years.

Indoor cats tend to live a little longer.

The Siamese has a lifespan of 15 to 20 years if they are indoor cats, or 12 to 20 years if they aren’t.

That’s a long lifespan for a cat breed.

The Maine Coon Siamese mix should have a a good 15 years of life as an average.

Health And The Maine Coon Siamese Mix

The online information about Maine Coons will primarily focus on the health of a purebred.

Some breeds are more susceptible to showing various diseases or conditions.

One thing that Maine Coons are known to have an increased risk for is polycystic kidney disease (PKD).

It isn’t uncommon for other breeds to contract PKD, but the Maine Coon is more susceptible.

It’s a more common occurrence in the breed than others.

Due to the parents of this particular mix being a Maine Coon and Siamese, let’s take a look at each breed individually.

Maine Coons are challenged by four common conditions;

  • polycystic kidney disease (PKD)
  • hip dysplasia
  • hypertrophic cardiomyopathy (HCM)
  • spinal muscular atrophy (SMA)

By contrast, the conditions for the Siamese are;

  • progressive retinal atrophy (PRA)
  • systemic amyloidosis
  • mediastinal lymphoma
  • asthma
  • hip dysplasia
  • upper respiratory infection
  • vestibular disease
  • mast cell tumors

While the Maine Coon Siamese mix would suggest that there would be a blend of the health issues of the parent breeds, hip dysplasia being the commonality.

Conclusion

If you go with a Maine Coon Siamese mix, the temperaments and personality traits are going to be very similar to both parents.

The Maine Coon Siamese cat would probably be good for people who like their cats to have dog like qualities.

Some owners of purebred Siamese feel they do not make ideal indoor cats given their well-known needs for lots of attention and interaction.

Oftentimes, Maine Coon Siamese mixes inherit the personality traits and other characteristics of their parent breeds.

As it is the Maine Coon is a laid back cat, the Siamese is very vocal and also a lap cat.

So this new mixed breed will provide plenty of interaction for its family but can also give space on other occasions when it needs that time alone to decompress.
