When researching for a new pet to own, you may have stumbled across the Munchkin cat. But how big do they get, on average, and what kind of size can you expect from them? Intrigued by this rather cute breed of cat, I spent some time researching them. I will be sharing all the information I was able to find regarding their proportions in this article here today.

So, how big do Munchkin cats get? Munchkin cats typically reach between 5-7 inches in height and weigh around 6-9 pounds when fully grown. They generally reach their full adult size by the time they are 9-12 months old. The Munchkin cat is therefore considered a medium-sized breed. Factors that influence their final size include nutrition, general health, quality of life, and other environmental factors.

If you have seen any pictures of the munchkin cat, then you will immediately be drawn to their somewhat unique appearance.

The Munchkin cat has short stumpy legs and a long spine. In many ways, it comes as no surprise to learn that this particular feline is considered to be the Dachshund of the cat world.

Beyond this, Munchkin cats are thick-bodied with a rounded chest, making them look out of proportion in many ways.

As such, this breed has a rather distinct way of moving; besides, they do need to navigate around with what they have got to work with.

Munchkin cat movements are in many ways akin to ferrets, where they are relatively low to the ground and quite sprightly. They do not really command the gracefulness as other longer-legged cats.

Let us now take a closer look at the average size of this breed, along with when you can expect a kitten to reach their full-grown adult size.

We will also be looking at some of the size considerations you will need to take into account, as an owner.

So, if you are contemplating getting one of these cute and distinct cats, be sure to keep on reading to discover and find out exactly what you can expect in regards to their size.

Average Munchkin Cat Height, Weight And Size

Munchkin cats have legs that are three inches shorter than the common house cat; otherwise, the rest of the body is typical of the average house cat.

Most adult Munchkins reach 5-7 inches in height and weigh 6-9 pounds. This feline is affectionately equaled to the Dachshunds of cats. Some even call this cat a “sausage cat.”

The munchkin’s short limbs result from a genetic mutation and are the most defining feature of the breed.

These cats have coats that come in different styles and color combinations that can be either short-haired, long-haired, or hairless.

Either type is well-weathered, and the coats give off a somewhat silky appearance. Long-haired Munchkins will have a plumed tail.

It does make them moderate shedders, though.

Regardless of their short legs, these cats let nothing stop them; they love to play and explore the world around them – they are an energetic cat breed just like most cats.

This cat can adapt well to most living situations due to their size, but they do still need enough room to run and play.

Besides, they do need to work up enough speed on their little legs to gain momentum!

Munchkin cats cannot jump on top of a bookshelf in a single leap like so many other cats, but they still are capable of and enjoy jumping.

Instead, it is commonly accepted that a Munchkin cat has only 50% of the jumping ability of other cats. Sofas, beds, and couches may be out of the question depending on their dimensions.

For this reason, it’s a good idea to get your cat a cat tree with a low entrance so that they can explore heights with more ease.

Equally, if you can set up your environment to support and assist them here, it will go down very well.

That is of course if you do not want them jumping up on certain surfaces or having access to specific areas.

Do Munchkin Cats Stay Small?

Munchkin cats stay short their entire life due to a genetic mutation. This is what gives them their distinctive stubby little legs trait.

This cat’s breeding is controversial because some believe that it encourages normalizing and promotes physical deformities in cats.

While it is true that short-legged cats have always existed, the earliest recordings of such are only as early as the 20th century.

One thing that is for sure is that the American Munchkin cat is purposefully bred to be short-legged.

The current breeding process involves matching one Munchkin, regardless of gender, with a cat who does not possess the short leg gene.

This is because the mutation will always be fatal when two Munchkins breed together. Even with this cross-breeding, the mutated gene will always be dominant over that of the normal cat. The result will be Munchkin litters.

We do need to consider that breeding a cat with short legs is generally for us humans and not necessarily for the cat’s benefit.

Short-legged cats may look cute, but it does not give this breed any advantages, make them happier or healthier.

On a lighter note, a munchkin cat is the world’s shortest living cat.

In 2013, a tortoiseshell Munchkin named Lilieput, from Napa, California, made it into the Guinness World Records as the world’s shortest living cat.

The cat stood a mere 5.25 inches from the bottoms of her paws to her shoulders.

So, whether or not this information is going to impact your decision on getting one is a decision that you will need to make.

It does depend on your stance and opinions, both from a moral and ethical perspective.

But one thing is for sure, these cats are typically bred properly and in similar ways to other breeds.

It just depends on whether or not you feel it is mean, or wicked, to own a cat with this limitation.

At What Age Are Munchkin Cats Fully Grown?

Munchkin cats are fully grown between 9-12 months old.

While they are shorter in stature than other household cats, they are longer in the body.

One observation from many owners is that males are generally anywhere from 5-20% taller and heavier than females. At their size, it’s not too much difference mind you.

Either way, kittens of all breeds put on weight rapidly during the first few weeks of life. We can see their typical growth rate below:

Age	Average Weight (In Pounds)
1 Week	0.3 – 0.6 lbs
2 Weeks	0.375 – 0.875 lbs
3 Weeks	0.75 – 1.1 lbs
4 Weeks	0.75 – 1.3 lbs
5 Weeks	0.875 – 1.8 lbs
6 Weeks	1 – 2 lbs
7 Weeks	1.2 – 2.3 lbs
8 Weeks	1.4 – 2.6 lbs
10 Weeks	1.8 – 3.1 lbs
12 Weeks	2.2 – 4 lbs
16 Weeks	4 – 5.5 lbs
1 Year	5 – 8 lbs

As you can see, most of a Munchkin cats growth happens within the first 16 weeks of life.

During this time a lot happens:

First 1–3 Weeks: Eyes and ears open,
Between Weeks 3-5: Begin walking and using the litter box,
Between Weeks 6-8: Start socializing and receiving first vaccinations,
Between Weeks 9-12: Move onto solid foods and maturing

It is at the 3-6 month mark that you will likely bring your Munchkin cat home. As you can see from above, a lot of their growth will have already been completed by this time.

They will however, continue to put on weight gradually over the course of the 7-9 months in your care.

At one year of age, when they tend to stop growing – they will no longer be considered a kitten.

At this stage and generally speaking, Munchkin’s legs will typically be at least three inches shorter than most other cats.

Despite their different walk and jumping challenges, Munchkins are relatively healthy, living between 12-15 years on average.

One thing to be aware of for this particular breed is that some kittens suffer from a condition called lordosis – which makes the muscles grow too short that the spine shrinks into the cat’s body.

This illness can be fatal in extreme cases.

Some Munchkins are also affected by pectum excavatum – a deformity that causes the cat’s breast bone to descend inwards.

Other cat breeds can suffer from either pectum excavatum or lordosis, and for this reason, many breeders contend that these conditions are not breed-specific.

Equally, they are considered somewhat rare. If you were to suspect your cat is suffering from a growth abnormality, then it is best to seek the advice of a veterinarian who will be able to examine and support your cat however they may need it.

Munchkin Cat Size Considerations For Owners

Munchkin cats do not require any extra medical care or attention other breeds. Their needs are similar to most other cats.

Certain factors can, however, impact their overall size. While some are definitely genetic, others are on the onus of the owner – and are usually related to nutrition general care.

So let’s elaborate on these factors to give you better insight into caring for a Munchkin cat if you did decide to get one:
