Siberian Forest Cat Weight By Age – A Full guide

The Siberian Forest cat, also known as the “Moscow Semi-longhair”, or “national cat of Russia” is one of the oldest domesticated cat breeds in the world. These loving and beautiful cats have a thick, luxurious coat that makes them all but invincible against the cold and yet somehow, they remain completely hypoallergenic.

As you might know, these are considered a large species of cats, but there’s a lot of contention online about how large they actually are and we are here to settle that today!

In this article, we’ll tell you what to expect for their weight as they grow, as well as health conditions which can affect their weight, and even throw in some diet tips and more. Let’s talk about your Siberian cat and their journey from kittenhood to adulthood and the things that you’ll need to know about that!

Siberian Cat Weight By Age

Siberian Forest Cats are quite large, ranking about 10th as far as the ‘largest cat breeds in the world’ go, but with that said you should still keep in mind that there are quite a lot of variables when it comes to determining size.

For instance, there are still quite a lot of feral Siberian cats out there in the wild, which are a little bigger than the domestic variety, who have been slowly becoming smaller over time and through breeding. Other factors, such as the age when they are neutered, their parent’s sizes, and even health conditions also come into play.

With that in mind, while this chart is certainly useful for having a basic idea of what to expect, just be sure to check with your vet before putting your Siberian cat on any kind of diet. Sometimes these furry little characters are simply shorter than most or taller than most and it’s perfectly fine!

We’ll go into some of those variables in a little more detail in the sections that will follow but for now, let’s get to the growth projections so that you’ll have a baseline of what you can expect in the years to come with your Siberian cat!

Before we jump into the hard statistical data, as a ‘general profile’ while Siberian Forest cats aren’t the tallest, they are one of the stockiest breeds out there. The males do stand at a respectable height of 9 to 12 inches/ 22.86-30.48 cm, while females are a close 8-11 inches/ 20.32-27.94 cm

While their thick and incredibly cold-resistant coats certainly make them look bulky, they are actually quite impressive beneath all of that too, putting them definitively in the ‘large cat’ category.

Here is an at-a-glance growth approximation for this cat breed:

Siberian Cat Weight kg Male Siberian CatFemale Siberian Cat
3 months 3 – 3.5 pounds/1.36-1.58 kg2-3 pounds/.90-1.36 kg
6 months4 -5 pounds/1.81-2.26 kg3-4 pounds/1.36-1.81 kg
9 months6-7 pounds/2.2-3.17 kg5-6 pounds/2.26-2.2 kg

3 years15 – 20 pounds/6.8-9.07 kg11-18 pounds/4.98-8.16 kg

We should note that on rare occasion, some Siberians can reach as much at 25 pounds/11.33 kilos by the 5th year of their 15-year life, though this is very rare, by their first year of age you will definitely notice why everyone says that this is a big cat breed. With these sweet cats, there’s definitely a whole lot to love!

Variables that can affect your Siberian’s weight

Siberians have a good amount of muscle, so their ribs should not be readily visible, though you can still feel them through the thick coat and the muscle. Also, if your Siberian cat has a somewhat ‘pouched’ belly, then don’t panic – this is completely normal and it’s known as a ‘famine pouch’.

Some Siberian cats have these and it’s simply there so that the cat may eat more when lots of food is available and this is just a survival trait that these cats have evolved with. Though famine pouches are slowly disappearing with domestication and cross-breeding, these odd belly additions are sometimes still present.

On the whole, these are a hardy and healthy cat breed, although some studies show that they have a risk for gingivitis and so if your Siberian cat seems thinner than usual and delicately picking up their kernels of late, then you might want check their teeth.

If spayed or neutered in adulthood, they may be smaller than Siberian cats that were spayed or neutered as kittens, as this can affect their growth, and at they tend to pack on a few extra pounds around their 5th year of life, it’s a good idea to get them started with healthy snacking habits early.

Siberian Cats – calories for proper nutrition

Your Siberian cat need to have approximately 50 to 60 calories for every 2 pounds/.9 kilo of body weight. This means that a 10 pound/4.53 kilo kitty will need 250-300 calories per day and if they are an adult, feedings should be done twice a day.

If your cat is a kitten or a young adult, more frequent feedings are recommended, as well as the higher 60 calories per every 2 pounds/.9 kilo as well. During this time, they are developing their bodies and the added nutrition will help to ensure that they grow up stocky and strong, as they are supposed to!

The feedings for these younger kitties should be 3 to 4 a day, but if your work schedule isn’t compatible with this, then you can either go ahead with 2 feedings a day or even better, invest in an automatic feeder.

Automatic feeders have been become quite popular of late and are inexpensive and easy to use, allowing you to preset a schedule so that a measured food portion comes out at the times that you’ve defined for your kitty’s meals.

Care considerations for the Siberian breed

Despite their thick, amazing coats, Siberian cats don’t shed as much as you might expect. That said, there are two times during the year when they do and it’s a good idea to get in the habit of brushing their fur well in advance.

During the spring, your Siberian will shed their winter coat, and this is when it’s going to be the most work. Without brushing, your cat might have furballs and if they sometimes groom after eating, they might lose a little nutrition in the process.

With this in mind, it’s a good idea to make brushing a regular thing, at least twice a week if you have the time. The next big shedding even comes in the fall, when your Siberian is shedding their summer coat, and its much less time intensive but a good brushdown is still the best idea.

Beyond the brushing, you don’t have a lot of worries with Siberian cats, as these are really quite the robust species. Just make sure if your Siberian is an indoor-only kitty that you give them plenty of toys to keep busy with and try not to overdo the fatty snacks – for the most part, your Siberian will do the rest!

Bonus tips about your Siberian’s diet

Since these are muscular kitties, they burn calories a little faster than less active and less physically robust species, but that doesn’t mean that they cannot end up obese.

While we mentioned that a pouched stomach is not a cause for alarm, if you see that the stomach is tightly pulled and looks a little distended, then your Siberian might well be overeating, and there are a few things that you can do to help them to cut down a little.

First off, if your Siberian likes to gobble up their food at a record pace, you can slow them down with a ‘slow feeder’ bowl. These bowls have grooves in them that catch and trap food, forcing your cat to slow down to pick the morsels out.

You can also put a tennis ball in the bowl and your cat has to eat around that, which accomplished the same thing. Beyond this, try to make sure that snacks only make up 10% of their daily caloric intake and this will go a long way towards your Siberian having a happy and healthy future.

Some final words on Siberian cats as they grow

Now that you have some basic guidelines, don’t forget that some of these cats may be a bit bigger or smaller than the average and that you shouldn’t start a new diet until you’ve checked with your vet. If you purchased your cat from a breeder, then we highly recommend checking with them to get the parent’s measurements.

While this isn’t 100% guaranteed to predict how your cat will grow, it should give you a fairly accurate idea MOST of the time so it’s definitely worth an email or a phone call. Aside from this, just be careful with those snacks and make sure that your cat is getting their recommended nutrition based on their body weight.

After that, just stick with proper nutrition and regular vet checkups, and don’t consider the growing ‘done’ at 2 years – unlike other breeds, Siberian cats can keep growing for up to 5 years before they reach their full potential.

If it’s your first Siberian kitty, then prepare yourself – Siberian cats are definitely a big, beautiful cat breed!
