Picture a cat that is large and shaggy like a Maine Coon, yet elegant and mysterious like the Siamese cat. The Maine Coon and the Siamese cat are extremely popular feline breeds, and a crossbreed between the two makes for a highly intelligent, lively, good-looking cat. These two highly desirable breeds make excellent companions, and a mix of the two can be a genuinely delightful kitty.

Crossbreeds are cats with parents from different breeds and will have some traits of each breed. Mixed breeds can be unpredictable. It is hard to know what they will look like. Crossbreeds can look like one parent or a mix of the two. They will inherit a blend of behavioral traits. Again, they can be more like one parent or a combination of distinctive characteristics from each breed.

Let us take a closer look at the Maine Coon Siamese cat mix and the history behind this interesting feline. Remember that mixed breeds can be unpredictable, and not all will be exactly the same. Our information is a guideline to help cat owners get to know this mixed breed. It is not a substitute for professional advice from a breeder or veterinarian.

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. Both breeds have been around for a long time and share some characteristics.

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. Because the Maine Coon cat is native to New England, the breed likely originated in America.

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 8 to 18 pounds fully grown. Males will be on the larger end of this. Some will even reach between 20 and 25 pounds. This breed 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.

They are considered native to Maine and serve as the official state cat. Maine Coon cats are sometimes called the dogs of the cat world because they are highly trainable and love to play games. They can even be trained to lock on a leash and play fetch. 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 tail. 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 8 to 14 pounds as adults. This breed can live from 8 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 is 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 known to be a highly intelligent, sweet, quiet breed. They enjoy a tranquil environment that stays calm. 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 will begin 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 will have telltale color point markings, and others may not. There is no particular way to predict precisely how these kittens will turn out unless one knows the parents and bloodline. Owners can try a 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 will likely result 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 will be a highly vocal and affectionate kitty. 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. This crossbreed is likely to want to spend a lot of time around humans but, like any cat, will need a quiet, safe place to retreat.

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 8 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.

This mixed breed is a moderate to generous size cat with a longer-than-average tail. They may or may not inherit the signature raccoon-like markings of the tail. These felines are usually a little bigger and longer than the average house cat. Large ears are possible, as both breeds have prominent ears.

Coat & Colors

This mixed breed may have a somewhat bushy rugged coat like the Maine Coon. They will 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. It is likely a mixed breed will have a double coat.

Coat color can vary. Maine Coon cats come in just about every color and pattern, as they already have quite a genetic mix. A blend with a Siamese will likely have some sort of 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 will impact how often they will need grooming. A short-haired kitty will need 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 breeds shed, but not excessively. Daily brushing will help 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 couple of 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 will need 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. These two places should not be close to each other. Keep your home free of debris and scraps of people’s food.


Cats are predatory creatures with a natural instinct to hunt and kill prey. Cats are looking for outlets for this behavior and need a healthy way to eat this internal drive. 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.

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 will mean 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.

Common Training For Cats

  1. No scratching on furniture
  2. Do not scratch people
  3. How to use the litter box
  4. Not to bite people or other animals
  5. Tricks and games
  6. Common commands like sit, stay, roll over, jump, high-five, play a game, time to eat, come here, etc.
  7. Grooming
  8. Be calm when in the car
  9. Proper behavior at night


Both parent breeds of this mix have long lifespans. A mix will also live a long time, likely longer than their parents. 10 to 16 or more years is a reasonable expectation. Health depends on many factors. Lifestyle, nutrition, and medical care all play a part. A mixed breed 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 can cause pain and even lameness if not treated.
  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.


Nutrition is a significant aspect of any feline breed’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 will provide this mix with a healthy diet.

Because of the large build of these cats, they will need a lot of food to sustain themselves. Expect to feed them about 3 cups of food a day. Split this into three or four meals. They will also need regular access to fresh water.

Breeders & Kitten Costs

Because this kitty is a mixed breed, the price of a kitten will often be 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 kitten. Depending on the breeder or seller, the price may be more. Reputable breeders will be 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 will 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 startup costs, 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 will 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.

Consider local shelters and rescue groups in your area if you are willing to adopt an older cat. There are some advantages to adopting an older kitty for people who are just not up for the challenge of training a new kitten but are looking for feline companionship.

As Family Pets

A Maine Coon Siamese mix can be a delightful feline companion. These kitties will be 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.

This breed is confident and outgoing, as well as quite vocal. They are not the best for tight and small households due to their larger size. These kitties will need considerable care, regular grooming, and room to play. They will do well with people and are great for families with young children. Owners must ensure that children have appropriate training in handling a cat.

Final Thoughts

A Maine Coon Siamese mix is one good-looking, highly intelligent, and large feline. A mix of these two beautiful feline breeds will surely be a happy addition to your family. Remember that all cats are different, and mixed breeds can be unpredictable. Cats are amazing creatures, and it is our great privilege to be able to have them in our lives. With this privilege comes the great responsibility of ensuring felines of any breed are healthy, get regular medical care, exercise, and proper nutrition, and are in a healthy environment.
