2 reasons why female Maine Coons are better than males

In human terms it is sexist to select one sex over another and I feel slightly uncomfortable doing it but this article should interest people who are thinking of adopting a Maine Coon cat (MC).

2 reasons why female Maine Coons are better than males

HCM

If you are thinking of adopting you probably know by now that the MC is predisposed to several inherited diseases, one of which is hypertrophic cardiomyopathy (HCM). It is a serious heart disease and ultimately a killer. It can start at a very young age. A breeder says that a cat predisposed to HCM should be tested for the disease yearly. How do you check?

This disease is present in the general domestic cat population and in other breeds at a higher prevalence e.g., the Bengal cat at around 15% of all Bengal cats. It is also present in humans at 0.2% prevalence (1 in 500). However, 30% of Maine coon cats have a genetic mutation that makes it likely that they will develop hypertrophic cardiomyopathy.

Cats in general are more seriously affected. Why? We should know. The breeds are more seriously affected because of selective breeding.

So, it is a serious issue for MC adopters or should be because no cat caregiver wants their cat to be seriously ill and die before their time.

One genetic mutation which has been isolated as a cause of the disease is called MYBPC3-A31P. There are other mutated genes responsible.

The scientists on the UC Davis Veterinary Medicine, Veterinary Genetics Laboratory website say this:
"Additional information from these publications suggests that male cats may be twice as likely to be affected as females, and that heavier cats are more prone to develop HCM than lighter cats. However, this latter relationship may itself be attributable to a larger size for males than females. "
They say that male MCs are twice as likely to be affected by this mutated gene as females.  And that the weight of the cat is linked to the likelihood of developing the disease.

The simple conclusion is that female MCs are likely to be healthier than males on the 'predisposition to HCM scale'.

Hip dysplasia

Click for the overall prevalence of this disease. The second reason is that as males are heavier than females, they are more susceptible to developing hip dysplasia which as you might know is a loose hip joint due to another inherited genetic mutation. It causes lameness and arthritis.

The big MCs that we see and those that have hip dysplasia in both hips are more likely to have a more serious version of this joint disease.

This is another reason to state with a fair amount of confidence that female MCs are healthier than males at least with reference to this couple of diseases.

Adoption choice

This may affect adoption choices. It also points to the potential advantages of not choosing a huge and impressive MC (which we are all fond of looking at) but one that is more in line with the breed standard and a cat of a more normal size for this breed which is already very large.

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 .

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.

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

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

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

Parisian Maine Coon 'crème et blanc'

-

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.

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

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.

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

Dwarf Maine Coon cat?

-
Image
No, you won't get a dwarf Maine Coon cat. There is no formal cat breed which is a dwarf Maine Coon (MC) although there are about a dozen dwarf cat breeds which is strange because most people haven't heard of them. It would be a travesty of the distinguished Maine Coon cat breed to create a dwarf version. But is there is someone online discussing a Maine Coon x Munchkin mix. Well, I hardly read it because I can't see the point. Note : One study on Google Scholar reports on a Maine Coon kitten in Germany born with inherited dwarfism called metaphyseal chondrodysplasia. This is very rare as I understand it. This individual cat was a dwarf Maine Coon. The cat also suffered from rickets and other health issues. This was unplanned and unwanted. Fairly normal-sized Maine Coon. Photo: copyright Helmi Flick. Think about it. The MC is known to have a large and distinguished bearing. They are meant to be outstanding in that way. It is their raison d'etre. To cut them down to a s
