The History of Maine Coon Siamese Mix

Maine Coon Cats

Maine Coon Cat Walking on Snow 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.

Physical Characteristics of Maine Coon Cats

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

The Siamese in History

The Siamese is an ancient feline breed known to inhabit the area of the world now known as Thailand, formerly Siam. They made their way into Western civilization in 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.

Siamese Cat Characteristics

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.

Crossbreeding the Maine Coon cat with a Siamese

The decision to crossbreed the Maine Coon and Siamese breeds is driven by a desire to combine the unique traits and characteristics of both breeds. Maine Coon cats are known for their large size, robust appearance, and friendly personalities, while Siamese cats are recognized for their striking Colorpoint markings and vocal nature. By crossing these breeds, breeders aim to create a cat that possesses a mix of these traits, resulting in a unique and appealing companion animal.

Size & Appearance

Maine Coons are the largest domestic feline breed in the United States. Siamese are smaller, so any mix of the two can range from 8 inches to 40 inches. They will grow to be 8 to 18 pounds, and the life span of these beautiful babies is, on average, 8 to 15 years. 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.

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 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.

Child Friendliness

The Maine Coon Siamese mix tends to be child-friendly, making it an excellent choice for families with children. Both parent breeds are known for their friendly and playful natures, and these traits often carry over to their mixed offspring. However, it’s essential to teach children how to interact respectfully with any cat to ensure a harmonious relationship. Supervision and guidance are crucial to prevent any unintentional rough handling.

Canine Friendliness

While this mixed breed is generally friendly and adaptable, its compatibility with dogs or other pets can vary from one individual to another. Early socialization and gradual introductions can help foster positive relationships between the Maine Coon Siamese mix and other animals in the household. Cats and dogs can learn to coexist peacefully, but it may take time for them to adjust to each other’s presence.


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 Care and Nail Trimming

Dental hygiene and nail care are two areas that often get overlooked in grooming. Felines do pretty well with cleaning their 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 an 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

  • No scratching on furniture
  •  Do not scratch people
  •  How to use the litter box
  •  Not to bite people or other animals
  •  Tricks and games
  •  Common commands like sit, stay, roll over, jump, high-five, play a game, time to eat, come here, etc.
  •  Grooming
  •  Be calm when in the car
  •  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:

  • Polycystic kidney disease is an inherited disease that causes fluid-filled cysts in the kidneys that can cause kidney failure.
  •  Congenital heart disease and defects like aortic stenosis.
  •  Amyloidosis is a condition in which proteins deposit outside cells, causing massive dysfunction throughout the body.
  •  Asthma and other respiratory concerns.
  •  Hip dysplasia is a genetic malformation of the hip joint that can cause pain and even lameness if not treated.
  •  Hypertrophic cardiomyopathy is caused by abnormal genes in the heart.
  •  Spinal muscular atrophy is a genetic disorder that causes the loss of spinal cord nerves in Maine Coon cats.
  •  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 higher.

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.

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 mix to 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 could be better 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.
