Siberian Cat vs. Maine Coon: Which Cat Is Best for You?

Maine Coons are a natural breed that likely developed in the state of Maine. 

“They were working cats. They were the barn cats of New England,” says Vickie Fisher, past president of EveryCat Health Foundation, previous president of The International Cat Association (TICA), and long-time pet parent to Maine Coons.

Although there are several tall tales about their history, such as one that suggests they were the result of breeding between domestic cats and raccoons, it’s most likely that Maine Coons came about from matings between shorthair domestic cats and longhair breeds from overseas.

Siberians, as their name suggests, are natives of Siberia, where their triple coats shielded them against the cold, subarctic temperatures.

According to TICA, Siberian cats have references that date back to 1000 CE, although they did not make their cat show debut until centuries later in the 1870s. Cat fancy was not popular in Russia until the 1980s, so records about the Siberian breed before then are sparse.

While Maine Coons and Siberians are both large, longhaired cats, these breeds have several distinguishing features that set them apart.

• Size: Maine Coons are the largest domestic cat breed and can grow up to 7 pounds larger than the biggest Siberian cats. “They’re very long and rectangular, so they can fill out a very substantial skeletal frame,” Fisher says. Maine Coons can weigh 12 to 22 pounds, while Siberians are typically 12 to 15 pounds.
• Coat: Both breeds have long coats with longer hair around the neck. This lion’s mane-like feature is called a frontal ruff. While the Siberian’s coat is triple-layered, the Maine Coon is double-coated. Both shed regularly year-round, with heavier spring and fall shedding seasons.
• Muzzle: Maine Coons have a prominent, angular muzzle that stands out from their broad cheekbones with large, expressive eyes on either side. The Siberian muzzle is smaller and more rounded. 
• Ears: Siberian cats have medium-sized ears with rounded tips, while Maine Coons have large, pointed ears. Both breeds have long fur growing from the tips, known as “ear tufts” or “lynx tips.”
• Tail: Both breeds feature bushy tails, but the Maine Coon’s is longer.

Chalk it up to their similar backgrounds as naturally bred hunters, but the Siberian and the Maine Coon display a comparable list of traits, all of them pretty sweet.

Both are known for being affectionate on their own terms. They’ll follow you around from room to room to be in your company, although neither is much of a lap cat. Maine Coons might bond with one particular person more than a Siberian does. They’ll show their affection with gentle headbutts and extra attention. 

Both breeds are also known for being talkative. They will trill, grunt, and chirp more than meow.

While they may not be quiet, they are certainly easygoing. These are two cats who get along very well with kids and other pets, making them excellent family cats, as long as you don’t mind the chatting and the necessary grooming. 

Every cat has their own nuanced personality, but after decades of raising Maine Coons, Fisher has found that Maine Coons are the most doglike of the cat breeds.

“The Maine Coons are a little more outgoing, a little more cocky, I think, than the Siberians,” Fisher says. 

Neither the Siberian nor the Maine Coon are particularly energetic cats, so pet parents will need to do their part to encourage play. 

Aim for at least 20 minutes of activity per day for either breed, but more is always welcome. Their daily exercise is “best split into short 10-minute play sessions,” says Dr. Maggie Placer, DVM, veterinary science program manager at EveryCat Health Foundation.

“As both breeds are large, heavy, and playful, regular activity is important to maintain a healthy weight, good joint health, and to engage their high intelligence,” she says.

Siberians and Maine Coons are natural-born hunters, which means they’ll enjoy any activity that engages their natural prey instinct. Think puzzle feeders and boxes, cat wands, and other interactive toys. 

Many Maine Coons have a particular fascination with water, so they may enjoy some supervised play time in shallow water, like in a bathtub or kiddie pool. A game of fetch with crinkle balls or mouse toys is another popular option.

Both breeds can enjoy exploring the outdoors on a leash, especially when trained as a kitten.

All cats need vertical space to explore, so provide plenty of sturdy, high-up perches. If your cat is on the larger side, make sure all cat trees, shelves, and window seats can hold their weight.

Longhaired breeds like the Maine Coon and Siberian need regular grooming to keep their coats healthy and detangled. Skipping the necessary grooming steps could result in matting, which can lead to skin irritation and infections.

For both breeds, use a wide-tooth comb like the Andis Steel Pet Comb to gently comb your cat’s coat at least once a week.

During the shedding season in spring and fall, Siberians and Maine Coons blow their coats. This makes them more prone to matting, so they’ll need to be combed more frequently, about once a day. 

If your cat does form some stubborn tangles and mats, a detangler like the Pet Republique Dematting Tool can help get them out.

“Despite their appearance as large, sturdy cats, Maine Coons face several unique genetic health risks,” Dr. Placer says. Common health considerations include:

• Hip dysplasia: The Maine Coon’s large size makes them susceptible to hip dysplasia, where the hip joint doesn’t fit together properly. This can lead to pain and arthritis.
• Spinal muscular atrophy (SMA): Maine Coons can also inherit a unique genetic degeneration of spinal nerves called spinal muscular atrophy, which results in weakness of the hind legs.

“As a large, heavy-boned breed, healthy weight management is required to avoid excess heavy pressure on their hips and spine,” Dr. Placer says.

Siberians share some genetic health risks that can affect Maine Coons, too, including: 

• Hypertrophic cardiomyopathy (HCM): This is the most common heart disease in cats, and both Maine Coons and Siberians are susceptible. HCM involves a thickening in the walls of the heart muscle. The condition can be fatal, so it’s important to see your veterinarian for regular checkups.
• Polycystic kidney disease (PKD): Siberians and, to a lesser extent, Maine Coons are at risk of polycystic kidney disease. This inherited condition causes fluid-filled cysts to form in the kidneys, which can ultimately lead to kidney failure. Thankfully, genetic testing is available so responsible breeders can screen for the condition. 

Breeders should also screen their Siberians for pyruvate kinase (PK) deficiency, a genetic disorder that can lead to hemolytic anemia. 

The Siberian cat and the Maine Coon both bring easygoing, affectionate personalities to the table. Add to that their gorgeous, long coats, and it can be hard to pick between them. Ultimately, it comes down to your personal preference.

Whichever breed you go with, be sure to give them the attention and care they deserve, and you’ll have a warm, loyal companion.
