As a national cat of Russia, the Siberian cat originates from the taiga in Siberia. These cuties are adorned with long-haired cats due to the forested areas and a bit colder weather, so they need to have a thick double coat.

Siberian Cat Size Comparison

When you look at a Siberian adult cat’s average size, it is shown that they can weigh around 8 to 17 pounds, of course, with males weighing a bit more than females. The length of the Siberian cats is about 17 to 25 inches when you start at the tip of their nose to their tail.

A Siberian adult cat’s average size is between 8 and 17 pounds, with the males typically weighing slightly more than the females. They measure about 17 to 25 inches in length from the tip of their nose to their tail.

The average lifespan of Siberian cats is 11 to 18 years. However, the important role in their lifespan has their genetic health, diet, and activity level while growing. These cats have interesting and gorgeous fur colors and patterns and usually blue eyes or even green if you’re that lucky.

Siberian Cat Vs Norwegian Forest Cat

Let’s start with comparing another cat breed that is imported from a cold region and gained a lot of popularity, the Norwegian Forest cat. Actually, these cats have many similar personality characteristics, but that is just because they are large lovable cats.

However, their size is quite different. The Siberian cat is evidently larger than a Norwegian Forest cat on average. However, some Norwegian Forest cats can look similar in size when you compare them to smaller Siberians.

The average size of these cats is around 9 to 16 pounds, with males being a bit larger than females. They are actually long felines with 12 to 18 inches in length from the tip to their large bushy tails.

Siberian Cat Vs British Shorthair Cat

Another domestic cat breed that we can compare to our Siberian cats is the British Shorthair cat which is also considered a large breed. But these cats tend to be thinner and longer than other felines.

That being said, British Shorthair cats are longer than Siberian cats, with 22 to 25 inches without the tail. However, they are quite often less bulky than a Siberian, with a weight of 7 to 17 pounds, making them longer and less heavy than Siberian cuties.

Siberian Cat Vs Ragdoll Cat

When it comes to Ragdolls, it is obvious that they are also large cat breeds. Being typically bigger than Siberian cats, female Ragdolls weigh about the same as male Siberians.

An adult Ragdoll can weigh from 8 to 20 pounds or even more, considering genetics and diet. If you exclude the tail, Ragdolls will still measure 17 to 21 inches from the tip of their nose.

You can easily recognize Ragdolls by their color-point coat and gorgeous blue eyes, which are quite a striking feature of them. When it comes to their nature, it is said that these cats share similar affection as the Maine Coons.

Siberian Cat Vs Savannah Cat

Savannah cats are medium to large breeds with leopard-like looks due to their coat full of spots on their back and necks with rings on their legs.

When we talk about F1 and F2 Savannahs, the usual weight mentioned is around 12 to 24 pounds and 16 to 20 inches from their nose, and their height is 18 inches.

When it comes to F3 to F6 Savannah cats, it is obvious that they are medium-sized cats with 13 to 17 inches in length and 10 pounds of weight. Anything less than an F6 is a domestic Shorthair cat.

However, comparing all these numbers, it is clear that these cats are slightly smaller on average than Siberian cats, even though they tend to be somewhat taller in the F1 or F2 generation.

Siberian Cat Vs Maine Coon

Finally, we have an obviously more giant cat breed than Siberians, the Maine Coons. As the largest cat breed that you can find, these cats weigh, on average, 18 pounds with a length of 36 inches from the nose to the tail.

Even though Siberians can be similar in size, they weigh up to 17 pounds, and their average size is relatively smaller. However, even though they are not the same in size, they share the same characteristics as being both lovely family pets with quirky personalities. Extremely social around other cats, these cats are fits for those with many pets.

Siberian Cat Vs Siamese Cat

Siberian cats are much bigger than Siamese cats. The average length of a Siamese is 11 to 14 inches long, weighing around 8 to 10 pounds. Siamese cats are considered small to medium-sized cat breed with more aristocratic traits than the muscular bodies of Siberian cats.

These cats tend to be quite moody and handful when it comes to making them at ease. But, the temperament is overlooked when you see how beautiful they are with their angular faces and gorgeous coats.

Siberian Cat Breed: History

The Siberian forest cat is believed to exist as a wild cat in the Russian forests for a thousand years. Old Russian children’s stories and fairytales are full of Siberian cats.

This cat breed has been for centuries in Russia; however, not long ago, the Siberians were recognized as a formal breed and bred for their aesthetic traits.

The year of 1871 is important for the Siberians since that is the time they have been in their first cat show with only four other breeds.

After the end of the Cold War, Siberian cats were found in the United States. In Britain, they’ve arrived in 2002, and since then, the number of Siberian cat breeders kept growing.

Siberian Cat Breed: Temperament

What are Siberian cats like? Siberian cats are naturally calm felines but tend to be adventurous and fearless if the situation requires them. Their sweet facial expressions only tell us that they are gentle, affectionate, and loving.

With a Siberian cat, you’ll have the best playmate. They love to play with all kinds of toys and remain active during their lives.

The interesting thing about these cats is that they tend to be very intuitive, with many owners reporting that their Siberian cats just feel when they need their moral support.

Did you know that these cats are referred to as the dogs of the feline world because of their adaptability, friendliness, and love for cuddles?

Siberian Cat Breed: Personality

Siberian cats are quite an intelligent cat breed that even plays fetch. These cats tend to be loyal felines, enjoying the company of other animals and kids.

However, these cats can be really quiet but also really melodic with their chirps, trills, mews, and purring. Siberian cats are fantastic jumpers, and some of them even like to be in the water as well. Don’t be surprised if your cat interrupts your concert while showering.

Siberian Cat Breed: Weight

Siberian cats are known to have athletic and stocky bodies. They can vary in size and weight from medium to large, but that just depends on their gender and muscularity.

While females can weigh from 10 to 15 pounds, male Siberians can weigh 15 to 20 pounds, with more muscular males weighing up to 25 pounds.

The body of a Siberian is barrel-shaped, with hind legs a bit longer than their front ones, and they have rounded-wedge-shaped heads. These cats are quite agile and acrobatic.

Siberian Cat Breed: Coat Colors

Siberian cats can come in all color variations. Interestingly, their colors and patterns can be dramatic and truly deep.

Their markings can be colorpoint, white, and even lynx point. But in general, they have a tabby patterned coat. Common colors are orange, blue, white, black, and gray.

When it comes to their eye colors, they are gold, green, or a mix of the two. Some can even have two different eye colors.


Siberian cats sport medium longhair coats. However, they are usually adorned with triple coats due to their icy origins. The coats are generally the shortest in the summer and thickest in winter, and the fur is waterproof and sturdy.

Many Siberians have bushy tails, ruff around the neck, and fluffy britches. Sometimes, they’ll have those lynx-like spots that we mentioned above on the ears. It may happen that they have hair on top of their ears which makes their rounded ears look pointed.

Siberian Cat Breed: Shedding

As every cat sheds, so do the Siberians. However, when you think about the quantity of their hair, it is not that scary.

You can expect that your Siberian sheds twice a year. Their long heavy coat sheds in the spring, while the shorter coat sheds in the autumn. You’ll probably groom your Siberian cat every day.

Siberian Cat Breed: Health Problems

It is quite known that all cats can have specific health problems. Cancer, kidney disease, urinary, crystals, and gum diseases are just some of the illnesses that are common to many cat breeds.

Happily, Siberian cats are a hardy and healthy breed overall, and according to studies, Siberians are one of those cat breeds with more genetic diversity within their population.

That alone makes them less prone to issues from inbreeding. Sadly they are still bred for their specific characteristics and therefore are prone to some health conditions, and that is usually heart disease.

Heart Disease (Hypertrophic Cardiomyopathy)

 Hypertrophic cardiomyopathy is a hereditary disease that is the reason for many death of house cats, and that condition can affect Siberian Forest cats.

This heart disease thickens the heath muscle and becomes rigid, leading to lethal blood clots, heart failure, and fluid in the lungs.

This disease can happen at any age but usually starts at one year old in Siberian cats if it happens to be the case. How does this disease show up? Only one defective gene is needed from the parent to result in heart disease. Some lines that are from heavy breeding can suffer the most deaths.

Since Siberians are a young cat breed, studies are still researching the genetics that causes HCM.

Siberian Cat Breed: Care

Along with their daily brushing, Siberian cats will need weekly nail trimming and ear checks in order to prevent infections. If you notice that the inside of the ear is dirty, try to wipe it gently with a cotton ball that you damped.

It is advised that you brush your cat’s teeth regularly in order to prevent gum and dental issues. The best way to get your cat used to grooming is to start early on, meaning that you’ll need to begin with all grooming habits when your Siberian is a kitten. That way, they will slowly accept it, and in no time, they’ll be used to it.

Siberian Cat Food

Siberians are carnivores like all cats. They need to have a diet full of animal protein since it builds and maintains muscle mass as well as manufactures hormones, antibodies, and enzymes.

Not only does the protein help muscle mass, but it also helps cats maintain proper pH balance, which is a great addition to the development of growth. Besides protein, cats need amino acids like taurine, which other animals don’t need. Animal protein consists of taurine.

Some food can help your cat with energy, like Omega-3 and Omega-6 fatty acids, which are essential, and also arachidonic and linoleic acids. For the immune system, vision, and reproductive health, DHA is needed.

Of course, we must not forget the vitamins and minerals that help them with their biological processes, like metabolism regulation and oxygen transportation. They also need antioxidants but don’t need carbohydrates, which can lead to diabetes, obesity, and other health issues.

Siberian Cat Grooming

Happily, even though Siberians tend to have a long and thick triple coat, the coat doesn’t tend to mat or tangle. So twice a week should be enough for a grooming session with a steel comb.

That way, their fur will be healthy and shiny, and you’ll help your cat with hairballs. As we said, these cats shed twice a year, so that you can expect way more hair in your home during those periods.

Siberian Cat Breed: Lifespan

The average lifespan of a Siberian cat is 12 to 15 years. However, the quality of that life totally depends on it. The environment, diet, breed, genetics, and lifestyle affect life expectancy.

However, the good thing is that these cats are not prone to many genetic health issues; overall, they live a long and happy life.

Are Siberian Cats Hypoallergenic?

Many breeders, when selling cats, claim that their cats are hypoallergenic. However, no scientific facts can back up this statement, and there is no evidence that any hypoallergenic cat breed even exists.

A cat-specific allergen called Fel d1 is responsible for allergies. And, yes, it is true that Siberian cats don’t have much of that allergen. However, Fel d1 is created in the perianal glands, skin, saliva, and tears. While you groom your cat, the distribution of that allergen happens. The allergen can also be found in feces.

But, 60 % of cat allergies are accounted with Fel d1, which means that at least 10 other substances that cats have can cause an allergic reaction. So you need to consider other factors as well.

Sometimes, Siberian cats with low levels of an allergen can produce kittens with low levels of allergen. If you’re looking for a cat that will not cause you tremendous allergic reactions, try to spend some time with that potential cat.

On the bright side, Siberian cats have a lower chance of triggering allergies.

Are Siberian Cats Good Pets?

I cannot think of any reason that would make a Siberian cat a bad pet. These vats have been treasured as family pets in Russia for a long time, and they’re still in that tone. These cats are known for their sweet and gentle disposition.

Their friendliness and patience with people, children, and other animals are truly remarkable. They adore spending time with their owners, whether it is cuddling in a lap or playing lots of games.

As they are a smart cat breed, they are easily trainable and have a lot of playfulness inside them!

Can Siberian Cats Be Outdoor Cats?

As Siberian cats are cats from forests of Russia and icy climate, the opinion stands that they would handle it well to be an outdoor cat.

However, many things need to be taken into consideration. For example, these cats are now domesticated cat breeds that spend their time in the urban setting in the modern day.

That’s why there have been many debates on choosing the best for the Siberian cat.

One thing about a Siberian cat being an outdoor cat will mean that they will exercise and they won’t be bored since they’ll feel their natural instincts coming to life when trying to hunt and stalk. And another plus is that the outdoor cat won’t have problems with obesity and other health issues related to that.

However, even though outdoor cats will be physically active and have fun outdoors, that puts them at greater risk of having serious diseases, injuries, parasites, and poisoning. When it comes to outdoor life, besides poisoning, there are theft, car collisions, and being trapped somewhere without having a chance to escape.
