Is spinal muscular atrophy (SMA) in Maine Coon cats painful?

-
Answer to the title question: While SMA can cause discomfort and weakness, it is not typically considered a painful condition in cats (source: ChatGPT). That does not say it does not cause pain. It does say that it causes discomfort which is a mild form of pain isn't it?! This is one of several inherited diseases linked to this cat breed, all of which cause discomfort to varying degrees. Hip dysplasia simply causes pain, bad pain I'd suggest as it causes arthritis - bone on bone. There is a question mark over whether it is cruel to breed this cat under the current circumstances as managed by the cat associations.  They accept these problems. They should not. It is unethical to continue breeding cats like this.

Note: UC Davis in the US have a DNA test for this disease.

Spinal muscular atrophy (SMA) is a genetic disorder that affects the motor neurons of cats, leading to muscle weakness and wasting. SMA has been reported in various cat breeds, including Maine Coon cats. It can start young at around 3 months of age. That, to me, is significant as it means that the cat will be burdened with SMA symptoms all their lives. I could not find any reliable information on the impact SMA has on the lifespan of Maine Coons. This greatly surprised me. But for SMA in children it can dramatically shorten lives depending it severity.

How common is it?

The prevalence (how often it occurs) of SMA in Maine Coon cats specifically is not well-documented in the scientific literature (comment: we should know this information). In general, the frequency of SMA in a particular breed can vary depending on the breeding practices of individual breeders and the prevalence of carriers in the breeding population.

If you suspect that your Maine Coon cat may have SMA, it is recommended to consult with a veterinarian who can perform a thorough physical examination and appropriate diagnostic tests. Genetic testing can also be used to identify carriers of the SMA gene in breeding cats, which can help to reduce the incidence of the disease in future generations.

Painful?

Spinal muscular atrophy (SMA) in cats is a progressive neuromuscular disorder that affects the motor neurons in the spinal cord, resulting in muscle weakness and wasting. While SMA can cause discomfort and weakness, it is not typically considered a painful condition in cats.

Comment on the above: This information comes from ChatGPT. It concerns cats obviously. It is remarkable that when you search for information about SMA in humans you get a different assessment on whether it is painful. Here is an example online:
"Fatigue, trouble breathing, and leg weakness are symptoms of adult-onset SMA."
This does not indicate pain per se but it does indicate distress and perhaps stress. Trouble breathing will be at best uncomfortable which is a mild form of pain.

Symptoms in cats

Symptoms of SMA can include difficulty jumping or climbing, decreased muscle tone, and muscle tremors or twitches. As the disease progresses, cats may experience difficulty standing or walking, and may become unable to support their weight. In severe cases, respiratory and swallowing difficulties can occur, which may require intervention to ensure the cat's comfort and well-being.

While SMA itself is not typically considered painful, cats with SMA may be at increased risk for injuries or other health complications due to their muscle weakness and limited mobility. It is important to work closely with a veterinarian to manage the cat's symptoms and ensure their comfort and quality of life. Pain management strategies may be appropriate for cats with additional conditions or injuries that cause discomfort.

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
