Breed History

Crossbreeding the Maine Coon cat with a Siamese can happen intentionally by a breeder or naturally. Because of the popularity of both parent breeds, it is not surprising that this mixed breed could come about naturally.

There is not much known about the first Maine Coon Siamese mix. They were not bred for any reason other than that feline owners liked the two breeds or as a natural pairing. Because the Maine Coon cat is native to New England, the breed likely originated in America. Understanding the parent breeds helps us more about this mixed kitty.

Maine Coon Cats

Maine Coon cats are a sizeable domestic feline considered native to North America. There are multiple urban legends about how this big breed wound up in Maine. A popular yet impossible tale claims these cats result from a raccoon and domestic cat mating, creating an interspecies hybrid.

A more likely explanation is that the breed is a mix of long and short-haired cats that traveled aboard ships, eventually making their way to New England. They bred and developed to survive the rough New England winters, eventually becoming what we know of as today’s Maine Coon cat.

Maine Coons are massive felines. They can weigh eight to 18 pounds fully grown. Some even reach between 20 and 25 pounds. Maine Coons can reach 30 to 40 inches and can live up to 15 years or longer. This breed stands out for its incredibly long, bushy tail with ringed markings. They are often described as rugged, with big, shaggy coats.

Maine Coon cats have some unique physical features. They have pointy, large, tufted ears and generous-sized bodies. These kitties have large oval eyes colored copper, green, and gold. Maine Coons often develop a thick ruff of fur, like a lion’s mane, on their necks. They are prone to heterochromia. This causes them to have different colored eyes with one blue eye.

Maine Coons are also known to be polydactyl, with an extra toe or two. While not every Maine Coon will have either of these conditions, they are relatively common in this feline breed. This big cat breed is quite vocal and makes an unusual chirping sound rather than the regular cat’s meow.

Siamese Cats

Siamese cats are highly recognizable for their sophisticated, elegant look. They have sleek coats and colorpoint markings on their face, ears, legs, and tails. Siamese cats come in long and short-haired varieties. Both have short, fine, soft hair. They have lighter coats with seal points, brown, tabby, gray, brown, smoke, red, cream, or silver colorpoints. All true Siamese have blue eyes. Siamese cats are muscular and lean, reaching about eight to 14 pounds as adults. This breed can live from eight to 16 years on average.

The Siamese is an ancient feline breed known to inhabit the area of the world now known as Thailand, formerly Siam. They did not make their way into Western civilization until the late 19th century. Their unusual appearance made them quite popular among fashionable crowds in London and America. Known for their distinct markings and blue eyes, the Siamese are a natural breed, not one created to look that way. They have been a part of developing many other breeds, including Oriental, Balinese, and Himalayan cats. They share a common ancestor with the Thai cat. Both hail from Siam. However, they were developed to be two separate breeds.

The Siamese is a highly intelligent, sweet, quiet breed. They enjoy a tranquil and calm environment. These felines are affectionate to a few trusted family members and do not like a lot of unexpected company. Siamese cats are strongly opinionated kitties who can be very vocal.

Siamese cats have a rare genetic mutation in the enzyme that controls the color of their coats. They are born all white. When their bodies reach a certain temperature, the color of their fur begins to change. This same mutation can cause mild color changes in their coat as temperatures change with the seasons.

Maine Coon Siamese Mix

A Maine Coon Siamese mix can result in a medium to a long hair cat with a slightly shaggy coat. Some have telltale color point markings, and others may not. There is no particular way to predict precisely how these kittens turn out unless you know the parents and bloodline. You can do a cat DNA test, which may help narrow things down. These tests can help screen for some health conditions as well.


Both these breeds are known to be highly intelligent, highly trainable, and with mild personalities. A mix of the two results in a very intelligent, friendly kitten. Siamese cats are a little more attached to their people than the Maine Coon, so a mixed breed might not be as aloof as a purebred Maine Coon. Both breeds are friendly and enjoy being around people. Maine Coon cats are known to be very independent, while Siamese kitties are a little clingier, so there is a chance this cat could be either.

Maine Coon cats have long been bred to be mousers and hunt small prey. Siamese cats are not known to have as high of a prey drive. Keep this in mind with any kind of Maine Coon mix. This breed has an active prey drive and may be prone to chasing small animals and other pets. It is probably a good idea to ensure that any kind of pet rodent, fish, or reptile is kept in a tightly closed enclosure.

It is quite likely this mixed breed is highly vocal and affectionate. Maine Coons are known for their unique chirping, and Siamese cats are often quite opinionated. This mixed breed kitty may chirp, meow, or some sort of combination of the two.

Size & Appearance

Maine Coons are the largest domestic feline breed in the United States. Siamese are not quite as big, so any mix of the two can range from eight to 18 pounds. Some may be larger. Both breeds are muscular, with long bodies. Size, coat length, markings, eye color, etc., all depend on which genes are dominant. Eye color can include blue, copper, yellow, green, amber, or even multicolored. These kitties may or may not have an extra toe.

The Siamese Maine Coon is a moderate to generous-size cat with a longer-than-average tail. They may inherit the signature raccoon-like markings of the tail. These felines are usually a little bigger and longer than the average house cat. Large, tufted ears are possible, as both breeds have prominent ears.

Female Maine Coons have narrower faces and more slender bodies than males. Male cats, in general, tend to be a bit larger than females, so there can be a significant size difference, even among siblings. This size difference may become more obvious if your cat takes after the gentle giant parent more.

Coat & Colors

This mixed breed may have a somewhat bushy rugged coat like the Maine Coon. They can have short to long-haired coats, which might be thin or thick hair. Maine Coons have thick double coats, while the Siamese has a single coat of fur, so expect something in between. Either way, this mix is likely to be a fluffy cat with a beautiful coat.

Coat color can vary with this mixed kitty. Maine Coon cats come in just about every color and pattern, as they already have quite a genetic mix. A blend with a Siamese may have some colorpoint markings, even if they have a long, shaggy coat. The coat color range can include solid and multicolored coats. Smoke, grey, brown, red, black, blue, white, orange, silver, tabby, tortoiseshell, seal, chocolate, blue points, and lilac points are all possible.


The Maine Coon Siamese mix may be long or short-haired. This impacts how often they need grooming. A short-haired kitty needs to be brushed at least once a week, while a long-haired cat needs to be brushed at least twice a week. For longer-haired cats, daily grooming may be necessary.

Expect some shedding with these cats. Both the Siamese and Maine Coon breeds shed, but not excessively. Daily brushing helps control the amount your kitty sheds. They will have seasonal times when temperatures change, and they shed more. Occasional bathing may be needed, about once every three or four months. Cats who spend more time outside may need more frequent bathing.

Dental hygiene and nail care are two areas that often get overlooked in grooming. Felines do pretty well with cleaning their own coats. However, they cannot trim their nails or brush their teeth. These tasks fall into their owner’s responsibility. These cats need regular teeth brushing (at least once a week) and nail trimming as needed. Long nails can present a health hazard and injury risk for these felines.

Living Requirements

This mixed cat needs some room to explore. Maine Coons are big, fearless felines who love to hunt, while the Siamese are known for their cleverness and confidence. So, any breed with these genes has an adventurous side. They need a home with enough room to roam and even a place to play outside.

Most importantly, felines need to feel safe and secure in their homes. They should have multiple hiding places and designated areas for their food and litter boxes, which should not be close to each other.


These kitties need plenty of exercise and the ability to let out their natural hunter’s instinct. A lack of exercise can affect their attitude, appetite, behavior, and overall health. Make sure your kitty has multiple opportunities every day for interaction and play.

Both Siamese and Maine Coon cats are muscular, energetic, and athletic. They need regular daily exercise. Try to offer some different varieties of toys. Felines love tunnels, climbing towers, laser pointers, and games. Maine Coons often learn to walk on leashes, so this mixed-breed cat may enjoy walking or playing outside. An interactive toy like the floppy fish helps keep their minds active, too.

A cat not getting enough physical exercise may become aggressive and attack people in the home, other pets, and visitors. Providing safe outdoor spaces and plenty of opportunities inside the house to release energy is essential. Consult a professional trainer if you believe your feline is not getting enough exercise.


The mix of the genetics of this feline means they can be stubborn, independent, and very smart cats. They can learn several tricks and may teach themselves to do others. Siamese can learn to open doors and climb shelves, so expect anything with a Maine Coon Siamese mix.

Even if you do not train your cat to do tricks, there is some basic training that every feline owner must be ready for. This includes proper litter box training, not scratching your furniture or walls, and not attacking or biting people or other pets in the home. You can learn more about how to discipline your cat in our guide, which can be very helpful when training.

Both parent breeds of this mix have long lifespans. 10 to 16 or more years is a reasonable expectation for a Siamese Maine Coon. Health depends on many factors. Lifestyle, nutrition, and medical care all play a part. A mixed Siamese Maine Coon may be prone to some of the following medical conditions:

  1. Polycystic kidney disease is an inherited disease that causes fluid-filled cysts in the kidneys that can cause kidney failure.
  2. Congenital heart disease and defects like aortic stenosis.
  3. Amyloidosis is a condition in which proteins deposit outside cells, causing massive dysfunction throughout the body.
  4. Asthma and other respiratory concerns.
  5. Hip dysplasia is a genetic malformation of the hip joint that, if not treated, can cause pain and even lameness.
  6. Hypertrophic cardiomyopathy is caused by abnormal genes in the heart.
  7. Spinal muscular atrophy is a genetic disorder that causes the loss of spinal cord nerves in Maine Coon cats.
  8. Tumors and cancer are common in felines, particularly mast cell tumors, lymphoma, squamous cell carcinoma, and bone cancer.

Keeping up with regular veterinary checkups and vaccinations is an important step in keeping your cat healthy. Due to the risk of developing health conditions, you may want to consider pet insurance for your cat. Pet insurance can help cover the cost of care in an emergency or a serious illness, allowing you to focus on your pet’s recovery rather than stress about medical bills. Learn more about what cat insurance covers in our guide.

Nutrition is a significant aspect of any feline’s health. Both the Siamese cat and the Maine Coon need a diet high in protein. Protein supports healthy growth and provides energy. They need healthy animal proteins like those found in tuna, salmon, beef, chicken, and pork. Healthy fats and fatty acids are essential for skin and coat health. A mix of well-balanced dry and wet food provides this mix with a healthy diet.

Because of their large build, these cats need a lot of food to sustain themselves. Expect to feed them about three cups of food a day, split into three or four meals. They also need regular access to fresh water.

It is important not to overfeed your cat, as obesity is a big concern for larger breeds. These mixed cats love food, and it is easy to let them overeat. Obesity puts extra strain on their bodies and can lead to other health issues, including feline diabetes. For that reason, you should not free-feed the Siamese Maine Coon. Consider a puzzle or slow feeder to slow them down when eating and help control portion sizes.

Breeders & Kitten Costs

Because this kitty is a mixed breed, the price of a kitten is often much less than the cost of their purebred parent breeds. You can expect to pay anywhere from about $100 to $400 or $500 for a Siamese Maine Coon kitten. Depending on the breeder or seller, the price may be higher. Reputable breeders are willing to answer questions, provide documentation on the parent cats, and guarantee their kitten’s health.

Expect to spend a few $100 to get a new kitten or cat set up in your home. Kittens need a few more supplies than older kitties. Kitties require a bed, crate, food, toys, treats, and possibly leashes or harnesses. Along with the cost of a kitten and supplies, expect about $500 to $1,000 to get a new kitten set up.

While there may not be many breeders specifically advertising having these mixed kittens, you can start by calling and looking into reputable breeders of both Maine Coon cats and Siamese cats. They can help direct you toward a reputable breeder. The Cat Fanciers Association is an excellent resource for finding breeders and cat shows.

Rescues & Shelters

It is highly likely that a Maine Coon Siamese mix cat may end up in a shelter or rescue. Shelter and rescue cats cost much less. The Humane Society of the United States, your local shelter, and your veterinarian are reliable resources for finding reputable shelters and rescue groups.

There are some advantages to adopting an older kitty for people who are not up for the challenge of training a new kitten.

As Family Pets

A Maine Coon Siamese mix can be a delightful feline companion. These kitties are intelligent, loving around people, exceptionally playful, and affectionate. These two parent breeds mixed together create an intelligent, unique feline that makes an unforgettable addition to the family. They are a popular breed for pictures due to their photogenic looks, with many owners sharing them on Instagram and other social media sites.

This breed is confident, outgoing, and quite vocal. Due to their larger size, they are not the best for tight and small households. These kitties need considerable care, regular grooming, and room to play. They generally do well with people and are great for families with young children.
