What is the weight range of the Maine Coon cat?

-

It is a useful question to ask because the answer might surprise you. I've mentioned it before, but the CFA, the leading cat association, do not insist through their breed standards that the Maine Coon cat should be big but TICA differ. The 'end product' is the choice of the breeders. The weight range of this popular breed reflects the cat association's breed standards.

Dr. Bruce Fogle DVM in his book THE ENCYCLOPAEDIA OF THE CAT states that the weight range is 4-10 kg (9-22 lbs). The lower weight applies to females which as you might expect are generally smaller than males. And it is a weight which is not untypical for a large number of non-purebred cats.

One website, 11pets, states that the average female weight is 11 pounds and the average male weight is 14.8 pounds. They also state that 25% of male Maine Coon cats weigh between 6 kg and 8 kg. And 30% of females way between 4 kg and 6 kg.

Another website states that the average weight of a Maine Coon cat varies between 8-25 lbs. The top end would be exceptional.

In my experience, the very big Maine Coon cats are created in Russia or by Russian breeders in other countries. That isn't exclusively the case but that tends to be what happens. In Britain, you will see more moderate sizes in my opinion.

And in America they do have breeders who breed what they describe as "European Maine Coons". They recognise that there is a difference between Maine Coon created in Europe and those that are created in America. And size is one difference. Another is extreme features.

Why are Maine Coon so heavy?

Maine Coons have a reputation for being the largest domestic cat breed. This is a result of breeders interpreting the breed standard in a way which suits them. Despite the fact, as mentioned, that the CFA breed standard does not state that the Maine Coon has to be large, but be a "solid, rugged" cat.

TICA, however, are more specific. They say that the torso should be "large, long, substantial". But what does 'large mean? Perhaps this explains why European breeders create larger cats. They will be affiliated to The International Cat Association (TICA) rather than the CFA. Or one of the European cat associations.

Of course, the word "large" is open to interpretation. The association breed standards don't state that this should be of a certain weight. They leave that to the breeders to decide.

And to produce stand out cats they tend to bring to extreme or at least that applies to some breeders. There are downsides because the inherited hip dysplasia sadly associated to this breed is exacerbated when the cat is bigger because they are heavier and weight is going to make a loose joint worse.

Which Maine Coon is the heaviest?!

We shouldn't really be asking that sort of question but the Internet tells me that the heaviest Maine Coon cat on record is Ludo who ways or weighed 34 pounds (is he still alive?). For comparison, the heaviest of the wild lynx cat species, the European lynx, weighs 30 pounds.  Pretty amazing that a Maine Coon has the same ball park weight.

In my opinion, the current world's biggest Maine Coon cat might be 'Kefir'. His size is astonishing. On March 3, 2022 he was two years old and weighed about 30 pounds at that time. As Maine Coon cats keep growing for the first four years of their lives, it is said, I expect him to beat Ludo at the end of the day!

The extreme Maine Coon face

-
Image
This is an example of extreme breeding. This is a Maine Coon but this cat is an extreme and rare example of this breed. This is not the way they look normally. This face is almost like an aggressive robot with the piercing eyes and the huge muzzle.  Or like a lion's head. The head looks enormous and very heavy. It looks unreal. But it also looks very impressive.  And purchasers like impressive-looking domestic cats. But this not the face of a Maine Coon that wins cat show competitions as it does not fit the breed standard as accurately as the more moderate winners (see below).  In fact, the CFA standard is clear in that the cat should have a balanced appearance although this cat was not bred under the CFA breed standard as I understand it (see below).  Click here for more on the kind of MC which wins at shows .

No part of a Maine Coon cat should be exaggerated

-
Image
It is interesting to read that the premier cat association, the CFA (Cat Fanciers' Association) - the cat association which really dictates (with TICA) how Maine Coons should look - makes it clear that no part of the cat should be exaggerated, and the cat should be "well-proportioned and balanced".  In other words, any form of extreme appearance such as a particularly heavy muzzle or particularly large ears with extra-long lynx tips are not going to be seen as advantageous in terms of winning cat shows or in terms of having an ideal appearance. As soon as I read that no part of a Maine Coon should be exaggerated, I immediately thought of the extremely large, extreme-bred Maine Coon cats that often come from Russia. These cats have very heavy muzzles.  Lion-faced Maine Coon with exaggerated features. Image in public domain now. In fact, their heads look like the heads of lions. I get the impression that breeders have selectively bred their cats over years to look like male...

Eerie picture of a Maine Coon sitting like a human on a chest of drawers

-
Image
This is a slightly scary picture according to those who've seen it. One social media user said it was the devil and "If I walked into a room and saw that, I would assume some shit is about to go down". There is a ghostly stillness and sinister feeling about the image. 'Eerie' is a better description. This attractive cat appears to be completely at ease and comfortable sitting on top of a chest of bedroom drawers. The lighting from below (deliberate?) enhances the eerie effect. It seems possible that this is a photo-edited image but if so, it has been done with great skill. However, I don't think this is Photoshopped. Rethink: to be honest, the more I look at the picture, the more I feel that this is a photo-edited image. It is just too unnatural to be real. Although some domestic cats get themselves into some very strange positions. Maine Coon calmly sitting just like a human on a chest of drawers. Picture source unclear.

Black smoke Maine Coon Richie with a black face and diamond eyes

Image
Black smoke Maine Coon Richie with a black face and diamond eyes. Photo: Instagram. OMG, this is a Maine Coon with an amazing face. His full name is "Richie du Mont d’Even". I think he has a black smoke coat which has created this black face with the assistance of other genes (polygenetic influence?) and ears with piercing, diamond eyes. This is a very special cat. Richie looked very interesting but relatively plain as a kitten. Image: Instagram. His paws are balls of fluff. He has a mane that goes over his head like a halo. He's angelic and other-worldly. The lynx tips on the end of his ears are smoky grey which makes them stand out. They are a bit like the opposite to the black lynx tips of the wild caracal.  He lives in France with his human: Adriana Piraino. He was born on 7th November 2020. He is still very young. They say Maine Coons reach adulthood at around the age of 4. He is going to be enormous as well. Richie with Adriana. Photo: Instagram Richie was bred b...

Comparison of a black smoke Maine Coon at 6 weeks and 6-years-of-age

-
Image
This is a cross-post as the image is so damned good. It is amazing because the cat is amazing. To put the same cat at different stages of their life in the same photograph is a nice idea especially with this Maine Coon (MC) who has an amazingly heavy face. It is so mightily masculine to be almost unbelievable. He has a priceless expression on his face too. Very serious compared to the innocence of his face when he was 6 weeks old. He looks a bit coy when 6 weeks old and a slightly grumpy middle-aged man when 6 years old. Comparison of a black smoke Maine Coon at 6-weeks and 6-years-of-age. Image in pubic domain. No doubt he is huge too. You get a clear sense of that in the image. There is a serious and less impressive side to this image. It's the backstory that people don't really want to read about and discuss or in fact do anything about: heart ( HCM ) and joint disease. The bigger and heavier the MCs are the more predisposed to heart disease they are. Here is the posts on...

Parisian Maine Coon 'crème et blanc'

-
Image
PARIS: This is a handsome Parisian Maine Coon described by his human caretaker as: "My little lynx Jiyuu of Roswell Maine Coon crème et blanc 19 mois mâle". The translation is: his name is Jiyuu of Roswell. His coat is cream and white. He is 19 months old. Oh, and his is damned handsome. The photo is by his guardian: Lunatique- girl . Cream and white Maine Coon living in Paris, France. Photo: Lunatique Girl. It is a really nice Maine Coon photo of a really nice Maine Coon with an interesting coat colour. I think the main colour is more milk chocolate, cappuccino or fawn! Anyway, super-looking cat. Is he a cream tabby? I think so.

Maine Coon size versus dog size?

-
Image
People want to know how the size of the Maine Coon compares to the size of a dog. You probably realise that it is impossible to answer this question because dog size varies enormously. This is due to selective breeding over about 20 years or more. And, it has to be said, the size of the Maine Coon also varies considerably.  A Beagle versus a large Maine Coon comparing size.

2 top Russian Maine Coon cat breeders which ship internationally

-
Image
I am writing this from the West; specifically, near London, UK. There will be quite a few people living in the West who'd like to adopt a Maine Coon cat and they would like to adopt one from a Russian breeder because they do have a certain style.  I sense, although I don't have hard evidence to support this feeling, that the top Russian breeders of Maine Coon cats might be superior to breeders from other countries.  I am putting aside Putin's invasion of Ukraine when writing this article. Some people might object to dealing in anyway with a Russian business on account of that barbaric and illegal invasion. We should remember that Russia has quite a strong cat fancy. They like their cats and they love their purebred cats particularly the Maine Coon. It is in fact a cat breed which is quite naturally suited to the Russian way of life and climate. There's lots of space in Russia with a relatively low population and therefore there are going to be houses with large grounds ...

5 Maine Coon transformations from kitten to adult (video)

-
Image
Maine Coon kitten and his adult self. Photo: Robert Silka. This is a series of photographs by the very famous Maine Coon photographer: robert_sijka. I think he presents his photographs too dark as there is not enough information in the photographs for my liking but he takes great photographs of great Maine Coon cats. In this series he photographs a kitten and their adult version. Each individual cat is a wonderful example of the Maine Coon breed. I can count five examples. In my experience, these Google Blogger videos only work if you click the centre play button and then, immediately afterwards, the play button bottom-left! It sounds bad but the short video is worth watching.

Difference between Maine Coon and domestic long hair

-
Image
The difference between a Maine Coon cat and a domestic longhaired cat comes down to the fact that the former has been artificially bred (selective breeding) whereas the latter has usually procreated according to natural selection. Natural selection is random breeding and therefore the domestic longhair is a random-bred cat whereas, selective breeding produces a purebred, pedigree cat registered with a cat association.  Difference between Maine Coon and domestic long hair. Infographic by MikeB. And because each individual Maine Coon cat is registered with a cat association, if they are in genuine Maine Coon, their appearance should comply with the association's breed standard . The breed standard tells breeders what their Maine Coon cats should look like in order that they can win cat show competitions if they want to enter their cat into these competitions. And so, as the appearance of Maine Coon cats is moulded to the guidance of a breed standard (see a section below from the...
