When you first take a kitten home, they are so tiny that it can be hard to imagine what they will look like when they’re all grown up. With some of the larger, heavier breeds the change can actually be pretty dramatic!

Chartreux cats are known to be pretty sizeable animals as adults, but they do take a bit of time to get there. Females are usually relatively medium-sized cats, but an adult male will almost always be large for a domestic breed.

Some cats will naturally be a little larger or a little smaller than average, and that is not necessarily anything to worry about.

How Quickly Do Chartreux Cats Grow?

Some cats are relatively quick to reach their full adult size, but this is not the case with a Chartreux! It can be three years or more before they reach physical maturity, especially for males.

You will typically see the most change and growth within the first 12 to 18 months of their lives, but they are not actually finished after this point.

Although they tend not to get too much larger, they can change and fill out a little as they mature over the next couple of years.

A Chartreux kitten usually gains between 0.5 and 1 pounds per month (if not a little more!) until they reach about 12 months old. Then, their growth will slow down.

Often, they have major growth spurts between 3 and 6 months of age, but this is not always the case.

Just like with humans, growing up and getting older is a very unpredictable business for a Chartreux cat, so don’t be surprised if your kitten is not putting on the exact same amount of weight every week or so, or they are not following the pattern that you expect.

You should only be concerned if your Chartreux is gaining less than 0.5 pounds for multiple months in a row.

If that is the case, then you should contact your vet and have them examined, as they may be malnourished or struggling with some kind of medical condition.

How Big Are Chartreux Cats?

One of the many things that make Chartreux cats such a beloved and sought-after breed is their large size and impressive physical presence.

They have quite a regal look about them, and they are strong and solid animals, although they don’t actually take up that much space in a room.

Most Chartreux cats measure between 8 and 11 inches in height and are between 15 and 18 inches long, which is not excessive in the domestic cat world.

A lot of their weight comes from the fact that they have dense bodies, strong bones, and substantial muscles.

These cats are a powerful breed, and they look like they’re built for work, although they actually have quite short and dainty legs in comparison to their broad shoulders and deep chests.

Do Chartreux Cats Have Long Fur?

When it comes to size in the cat world, fur can make a big difference. The infamously gigantic Maine Coon, for example, has long hair that makes it appear even bigger than it already is!

Chartreux cats do not have particularly long hair, but their coat is quite dense and thick. 

They have a blue-grey top coat that is water-resistant, and a compact undercoat that can be quite challenging to run a brush through. They are lovely to pet though, as their coat has a slightly woolly texture.

Why Are Chartreux Cats So Rare?

For such a strong and healthy breed, it might come as a surprise to find out that Chartreux cats are actually quite rare.

One of the main reasons for this is because their numbers were greatly reduced during the First and Second World Wars, and there have not been very many Chartreux breeders around since.

The first records of these beautiful animals date all the way back to the 1500s.

A poem called “Vers Français et latins sur la mort d’un petit chat” (French and Latin verses on the death of a little cat) written by Joachim du Bellay in 1558 talks about gray-coated domestic cats living in France, where the Chartreux is believed to originate.

At the time, they were rat catchers and working animals, but the Chartreux as we know it today is a gentle and affectionate companion animal.

Are Chartreux Cats Noisy?

You might be a little cautious about bringing a larger cat into your household, expecting them to be intrusive and noisy because of their size. With a Chartreux cat, however, it is quite the opposite!

The Chartreux is known to be gentle, affectionate, and well-behaved. They are rarely aggressive or destructive in any way.

Instead, they have a polite, calm nature that makes them very easy to spend time with and gives them the illusion of being quite diminutive, despite how large they actually are.

They are also incredibly quiet cats, with very soft voices. Some Chartreux cats are even completely mute, barely making any sort of sounds at all!

These cats are very loving animals that form strong bonds with their owners. The Chartreux has a reputation for following their favorite person wherever they go, although they are sometimes wary of strangers.

Is My Chartreux Cat Overweight?

The number on the scales can be pretty deceptive, and it’s best not to rely on it too much when you’re thinking about your cat’s health.

A Chartreux can be quite heavy but still be within a perfectly healthy range for their size – remember, they are dense and muscular animals!

Chartreux cats are not particularly prone to being overweight or obese, but it is always something to be aware of as an owner.

Any breed of cat can overeat and put on too much weight, which will have serious consequences for their health.

You should keep an eye on your cat’s overall body shape, mobility, and energy levels, rather than worrying too much about what the scales say.

A Chartreux should have a slight inward curve at its waist, that you can see from above or feel from the sides.

You should also be able to feel their ribcage and hip bones slightly underneath their skin if you press gently with your palms. They should be active and agile as well, able to jump and climb with relative ease.

If you are at all worried about the weight of your Chartreux cat, then you should take them to the vet for an examination.
