Siberian cat size comparison—who’s the biggest of them all?

This Russian breed uninhibitedly displays their majestic beauty and captivating persona, attracting crowds of cat lovers worldwide. Siberian cats' glory comes in a relatively sizeable package, which some may find intimidating.

Despite their lion-like mane and proud posture, Siberian cats have a temperament of a cuddly teddy bear. Their friendly and loving disposition makes them wonderful companions.

Similar to Maine Coons, Norwegian Forest cats, Bengals, and Ragdolls, these kitties are considered a large breed, but how do they compare to one another and regular cats, and what's the size difference between them?

Untamed presents Siberian cat size comparison with other breeds and explains how to care for them so they grow into healthy and happy felines.

Siberian cat vs regular cat—size comparison

Siberian cats have somewhat different proportions than regular cats. Their backs are slightly arched and higher than their shoulders, and their hind legs are a bit longer than their front legs.

They are also significantly bigger than your regular cat. Check out the numbers:

Siberian cat size—the stats compared to other breeds

Siberian cats are larger than regular cats, but to understand how they compare to other kitties, here is an overview of the size of a few popular breeds:

The differences between Maine Coons and Siberians

At first glance, it's easy to confuse a Maine Coon and Siberian cat. They have similar fur length and preferably lynx tips on their ears. The breeds are also similarly built—well-boned and strong, with medium-length legs. That's where their similarities end.

The largest domesticated felines, Maine Coons are significantly bigger than Siberian cats. Maine Coons also have broad chests and tails as long as their bodies or even longer, while Siberians tend to be more barrel-shaped with a shorter tail.

These two breeds also have entirely different head shapes. A Maine Coon's head resembles a square, and these kitties have quite high and prominent cheekbones, making them unmistakably recognisable. In comparison, Siberians have rounded faces, similar to regular cats.

When it comes to their personalities, both breeds are terrific companions. They are lovable, social, and fun to be around.

Another feline that resembles a Siberian is a Norwegian Forest cat. In terms of character, they are equally lovable and friendly, but when it comes to size, there are considerable differences. Norwegian cats are significantly larger than Siberians, although particularly large Siberians can be similar to smaller Wegies.

Another difference is the body type. Norwegians have a shorter body with a higher rump and a triangular head shape as opposed to the rounded Siberian.

The differences between a Ragdoll and a Siberian

The next Siberian lookalike is a Ragdoll, but you can easily spot the difference upon close inspection. Ragdolls can grow much bigger than Siberian cats.

Ragdolls are also recognisable by their colour points and dashing blue eyes, although one Siberian variant features the same characteristics.

In terms of personality, both breeds are exceptionally affectionate. The difference is that Siberians are more active and playful, while Ragdolls tend to be laid-back and calm, which is great since they are also much higher maintenance than Siberians when it comes to grooming.

Siberians and Bengals seem to share no qualities other than high energy levels, playfulness, and a love of water. They have different body types, although both breeds are incredibly muscular and athletic. Bengals are lean and elongated, while Siberians tend to be stockier and more robust. Still, they are pretty much the same size.

What can affect your Siberian cat's size?

How big your Siberian cat will grow depends on several factors:

1. Genetics
2. Sterilisation status
3. Diet

How do genetics affect a feline's size?

Genetics plays a crucial role in your Siberian's size, and there is nothing you can do to change it. If your kitty's parents are large, the chances are your Siberian will be big as well.

While DNA determines your cat's height and length, you can influence their weight and growth rate. It’s essential not to overfeed your Siberian to make them bigger because the probable outcome will be an overweight cat. Obesity is a predominant problem among domesticated felines, and it's vital to keep your cat fit to avoid serious health issues, such as:

• Diabetes
• Heart disease
• Joint degeneration

What's the connection between desexing and size?

Fixed Siberians tend to grow larger than intact felines. The earlier you spay or neuter your kitty, the larger they seem to grow.

The only problem with sterilisation is that cats typically struggle with weight control, especially if they live indoors. Luckily, Siberians mature slowly and often grow until they are four or five years old. They remain active and kitten-like much longer, making it easier to keep their weight under control.

How does the diet affect your Siberian's growth?

You can't change your Siberian's length and height, but you can affect their weight and general physique.

The quality and quantity of food and the feeding frequency can significantly impact your kitty's weight. In general, the higher the quality of food, the smaller portions your cat will need, and the easier it will be to keep your cat at a healthy weight.

What's the ideal diet for your Siberian cat?

Meat, fish, and a little bit of fat—your Siberian cat needs nothing else.

Your Siberian cat's diet should consist of the same nutrients they would eat in the wild. In nature, cats hunt tiny animals, such as:

• Small birds
• Mice 
• Lizards
• Large insects (moths and grasshoppers)
• Slugs
• Frogs

Since felines are obligate carnivores, whatever type of food you choose—dry, wet, semi-moist, raw, or homemade— it should predominantly contain animal protein. Meat and fish are the primary energy sources for felines and deliver essential amino acids (taurine and arginine), vitamins, and minerals cats need to stay healthy.

Here is the ideal composition of cat food:

The best ingredients for healthy meals for your Siberian are:

• Chicken (cooked, not raw)
• Turkey
• Duck
• Salmon
• Sardines
• Prawns
• Mackerel
• Tuna
• Liver

Pork, ham, and bacon are natural taste enhancers, but serve them in moderation as they are pretty high in fat. Fish and seafood deliver healthy fatty acids, crucial for the feline immune system, cell integrity, and skin and coat health, which is why cats should eat fish a few times a week.

You must always check the ingredients list of the product you plan to buy. Skip the ones containing vegetables, grains, or fruit because they are not compatible with the feline digestive system.

Here are some vegan protein sources to avoid:

• Rice
• Soya
• Corn or sweetcorn
• Wheat
• Peas
• Carrots
• Beans
• Pumpkin
• Broccoli
• Potatoes or sweet potatoes

What's the problem with carbs?

High-carb cat food can cause:

• Gastrointestinal problems—Cats lack the enzymes necessary to process carbohydrates, which can lead to various uncomfortable conditions, including:
• Indigestion
• Vomiting
• Diarrhoea
• Irritable bowel syndrome
• Flatulence
• Obesity—Carbs deliver fast-release energy. After the initial high, energy levels drop suddenly, making the cat drowsy and slow. The unburnt calories quickly turn into fat cells
• Metabolic problems—Carbohydrates can put a strain on a feline's pancreas leading to diabetes

Are Siberian cats good pets?

When picking a feline companion, size should not be the only factor to consider. If you are considering adopting a Siberian cat, you should learn about their:

1. Personality
2. Health
3. Grooming needs
4. Hypoallergenic status

Are Siberian cats friendly?

Siberian cats are fantastic companions. They are friendly, fearless, playful, and docile.

These kitties enjoy meeting strangers, get on well with kids and other pets, and thrive when given a lot of attention. They are also highly adaptable and have no issues getting used to environmental changes (provided they don't happen too often and suddenly).

It takes about five years for Siberians to fully mature, so they will be kitten-like for a long time. They will stay active for a long time, so give them attention and ensure they have a safe and stimulating space to run around and jump.

Besides their high activity levels, you also need to tend to their intellectual needs. These felines are smart. Siberians are problem-solvers and appreciate a good challenge. Provide them with a lot of interactive toys and food puzzles, so they can entertain themselves and stay out of trouble. Although they are not inherently mischievous, Siberians might get into a cabinet or two if they have nothing better to do.

Many Siberian cat parents say these kitties resemble dogs. They like to greet people at the door, and one of their favourite games is fetch.

Siberian cats are quiet and tend to chirp and trill rather than meow. There is no difference between whether you pick a male or a female in terms of personality, but females tend to be more elegant than males.

Are Siberian cats healthy?

Siberians are generally healthy. Their average lifespan is between 10 and 18 years, and with proper care and nutrition, they can surpass their life expectancy. Unfortunately, their sturdiness doesn't mean they are immune to specific hereditary health problems.

Some of the most common ones are:

• Hypertrophic cardiomyopathy (HCM)—HCM is the thickening of the heart muscle that makes it difficult for the organ to pump blood efficiently. It is the most common heart condition in felines affecting mostly males and older cats. Obesity is a massive risk factor, so keeping your kitty at a healthy weight is vital
• Polycystic kidney disease (PKD)—PKD is caused by a genetic mutation leading to the formation of numerous tiny cysts on a feline's kidneys. The cysts grow, straining the organs and leading to renal failure
• Feline lower urinary tract disease (FLUTD)—FLUTD includes several conditions, such as UTIs, bladder stones, cystitis, urethral blockage, and bladder cancer. Most of these are not life-threatening, but they are painful and can cause severe consequences if left untreated. Lack of hydration, inadequate diet, and stress are the most significant risk factors
• Gum disease—Dental issues are common in felines, and the usual culprits are poor dental hygiene and an inadequate diet that doesn't provide sufficient vitamins and minerals

Are Siberians difficult to groom?

Despite their long fur, Siberian cats are easy to groom.

The ritual should consist of:

1. Regular brushing—Siberians have a long triple-layered coat that doesn't mat or tangle easily, so brushing them once a week is enough. You can do it more often in winter and spring when they usually shed more
2. Occasional bathing—You should bathe your kitty every two months or when they get dirty. Siberians usually enjoy water, so bathing them should not be stressful. Still, don't overdo it, as frequent bathing can mess up their skin's PH value and cause skin problems and increased shedding
3. Frequent teeth cleaning—If you can, brush your feline's teeth every day to remove plaque buildup and prevent gum issues. You can clean their teeth with gauze on your finger if your Siberian doesn't like the toothbrush and only use toothpaste designed for cats
4. Periodic nail clipping—Your kitty will usually file their nails on their scratching post, but if you notice it's not enough and their claws are getting too sharp, you can trim the very tip with special cat clippers

Are Siberian cats hypoallergenic?

Unfortunately, Siberian cats are not hypoallergenic, and neither is any other cat breed.

A protein called Fel d 1 is responsible for most allergic reactions in humans, and since all felines produce it in their saliva, urine, and excrement, no kitty is truly hypoallergenic.

The good news is that Siberians produce tiny amounts of Fel d 1 protein, so they could be good companions for allergy sufferers. If you decide to bring this kitty to your home and you suffer from allergies, you should:

• Brush them more often and do it outside
• Dust and vacuum thoroughly and more frequently
• Use a HEPA-equipped vacuum cleaner
• Replace upholstered furniture

Keep in mind that if your allergic reactions to cats have been severe, you must consult a specialist before adopting a cat.
