Maine Coon Siamese Cat Mix

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. However, some breeders may specifically breed Maine Coon Siamese mixes. 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, or at least North America. To understand this mix, one needs to know both parent breeds. Remember, mixed breeds can be unpredictable and end up with a remarkably interesting combination of traits.

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, impossible tale claims these cats result from a raccoon and a domestic cat mating and creating an interspecies hybrid. However, that theory is 100% incorrect and biologically impossible. Another far-fetched story connects them to Marie Antoinette. 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. These cats then started to breed 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 is known for an incredibly long, bushy tail with ringed markings. They are often described as rugged, with big shaggy coats. This breed is known to be quite friendly and mild-tempered while retaining great skill as mousers.

Maine Coon cats have some unique physical features. They have pointy, large, tufted ears along with their exceptionally generous size. 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, 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. These kitties are incredibly friendly and want to be involved in everything their owners do. This big cat breed is also known for being quite vocal and having 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. Is there any usual appearance that made them quite popular among fashionable crowds in London and America? Known for their distinct markings and blue eyes, the same 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 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 when they want their opinion to be known. They like to be around their people all the time to help with whatever is happening.

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

Mixing the Maine Coon and Siamese cat can result in a medium to a long-haired cat with a slightly shaggy coat. Some will have the telltale Colorpoint markings, and others may not. Regarding mixed feline breeds, appearance is all left up to chance and specific genetic makeup. There is no particular way to predict precisely how these kittens will turn out unless one knows the parents and bloodline. Depending on the generation of mix involved, these cats may be more like one breed or the other.


Both these kept 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. This will likely be a noticeably confident feline that will enjoy both people and other animals. 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. The Maine Coon also takes longer to mature than other breeds, and they retain their kitten-like playfulness well into adulthood.

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 will likely have a reasonably active prey drive and may be prone to chase small animals and even 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. They both have a good relationship with other animals, so a crossbreed should not have too many issues with other pets. However, all felines are different, and every kitty has their own likes and dislikes.

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 Coon cats 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 will be 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 will most likely be a little bigger and longer than the average housecat. 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 Siamese have a single coat of fur. It is likely a mixed breed will have a double coat. Depending on the generation of hybrid a feline is, one may be able to tell this ahead of time.

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, gray, brown, red, black, blue, white, silver, tabby, tortoiseshell, seal point, chocolate point, blue point, and lilac point are all possible.


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

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 where 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 own nails or brush their own teeth. These tasks fall to 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. Siamese are known for their cleverness and confidence. So any breed with these genes can be expected to have an adventurous side. They will 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 curious and love to get into things. They can be allergic to many people’s nutrition. Trash and debris can be choking hazards, so always keep your kitty’s living area clean and tidy.


Cats are predatory creatures with a natural instinct to hunt and kill prey. Though they are domesticated pets, this instinct runs deep. 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. Providing them opportunities to chase things like laser pointers and cat toys will help them follow this instinct to hunt.

Both Siamese and Maine Coon cats are muscular, energetic, and athletic. A mixed-breed will 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. Make sure your kitty gets a couple of sessions a day of high-quality exercise for about 20 minutes each. Be careful not to overexert, but ensure they have an opportunity throughout the day to be active.

A cat that is not getting enough physical exercise may become aggressive and start to 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. Cats that are not getting enough exercise can start to have both physical and behavioral problems. Consult a professional trainer if you believe your feline is not getting enough exercise. They can provide different ideas for giving cats the opportunity for healthy play.


The mix of the genetics of this feline will mean they can be stubborn, independent, and very smart cats. They can be trained to do several tricks and will teach themselves many others. Siamese are known to learn how to open doors and climb shelves, so expect anything when it comes to what this mix can do. They may be extremely easy to train or have a stubborn streak, so this breed requires an owner to set firm boundaries.

Even if you do not train your cat to do tricks, there is some basic training that every feline owner needs to be prepared for. Along with house training and using the litter box, cats need to be trained not to be aggressive with people and other pets and not to do things like scratching furniture or climbing in things they should not.

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.
  • How to be groomed
  • Be calm when in the car


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. While both parent breeds are healthy overall, there are some medical concerns they are predisposed to. A mixed breed of these two felines 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 are deposited outside of cells causing massive dysfunction in tissues and cells 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 a condition 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 one of the most important aspects 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. Animal proteins are much preferred over plant-based proteins. 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. Some owners may want to add raw meat here and there as a boost. Always discuss proper nutrition with your veterinarian and consult before adding anything like raw meat or making a substantial dietary change for your feline.

Because of the large build of these cats, they will need a lot of food to sustain them. Expect to feed them about 3 cups of food a day. This can be split into three or four meals. They will also need regular access to fresh water. Leave multiple bowls out around the house and keep them fresh. Both parent breeds are felines that love water and like to play in it. Cats tend not to drink enough on their own, so leaving multiple bowls out will help encourage them to drink. Proper hydration is just as important as nutrition for felines.

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, allow you to see their facility and previous letters, and guarantee their cats’ health. Ask to see documentation, particularly genetics and health testing. Keep an eye out for graders who refuse to answer these questions or produce many litters every year. This signifies a kitten mill and not a healthy, reputable breeder.

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. However, those will require a bed, crate, food, toys, treats, and possibly leashes or harnesses. Along with the cost of a kitten and startup costs, expect to spend about $500 to $1,000 to get a new kitten set up in your home.

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 towards a reputable breeder. You can also check with your veterinarian to see if they know of any breeders or kittens of this mix available. You can also check out cat shows and investigate there, as these are great environments to meet other cat people and breeders. 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. Both are prevalent breeds that will range from several hundred to over $2,000 for high-quality bloodlines. Shelter and rescue cats will cost much less. Mixed breeds can end up in shelters for many reasons, and there are numerous ones across the country dedicated to connecting cats with good homes. The Humane Society of the United States, your local shelter, and your veterinarian are reliable resources for finding reputable shelters and rescue groups.

Across the country, shelters and rescue groups are overwhelmed with stray cats and kittens that need good homes. Older cats are often left in shelters with no hope of finding a new home. Consider local shelters and rescue groups in your area if you are willing to adopt an older cat. There are often kittens in these facilities as well. There can be 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 mixed kitty can be a delightful feline companion. They can make wonderful family pets. These kitties will be intelligent, loving around people, exceptionally playful, and affectionate. They will also be quite vocal and curious, wanting to be involved in everything their people are. These two parent breeds mixed together create an intelligent, unique feline that will make an unforgettable addition to the family.

This breed will be confident and outgoing, as well as quite vocal. They may not be 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. However, they may not appreciate being handled and tossed about. Homes with young children may not be the best fit for a particular feline, so owners need to ensure that children are appropriately educated on handling a cat.

Final Thoughts

A Maine Coon Siamese cat mix is one good-looking, highly intelligent, and large feline. This mix comes from two powerful parent breeds. Though they look different and have a noticeable difference in size, these cats are relatively similar in other ways. Both are very curious, smart, and athletic. These felines love to be around people and are vocal. The parent breeds love people and are affectionate, so a mix will also. A mix of these breeds may look like a very shaggy Siamese cat or resemble more of a Maine Coon or Siamese. There is always a bit of a mystery and unpredictability with mixed breeds regarding how large they will be and how they will look.

A mix of these two trendy, beautiful feline breeds will surely be a happy addition to your family. Remember that all cats are different, and mixed breeds can be unpredictable. There is no real way to tell what a cat’s personality or appearance will be until they are fully grown, and this mixed breed may take a little longer than other felines to fully mature. 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, proper nutrition, and are in a healthy environment. Felines need a high level of care throughout their lives to live as long, healthy lives as possible.
