Bilateral slipped capital femoral epiphysis in a female Maine Coon is rare

-
Image
Lexie. Picture: Express. I've written about slipped capital femoral epiphysis before and about its prevalence in the Maine Coon cat breed and you can read those articles by clicking on links below if you wish. Interestingly I bumped into a recent article online on the Express newspaper online in which a veterinarian accepted a female Maine Coon cat patient with bilateral slipped capital femoral epiphysis and he said that it was the first time he had seen a female patient with that disease affecting both hind limbs in 30 years of being a veterinarian. Obviously it's a very rare condition when it's bilateral and it concerns the female Maine Coon. Maine Coons are 12 times more likely to develop "slipped capital femoral epiphysis (SCFE) How prevalent is slipped capital femoral epiphysis (SCFE) in Maine Coon cats ? The owner was unaware of what the health problem might have been. As it happens, the cat's owner and the cats became part of a Channel 4 television programme...

The prevalence of hip dysplasia in Maine Coons is very similar for all geographic regions

-
Image
A study found that no matter where the Maine Coon was born they have a very similar chance of developing hip dysplasia. Here is the chart: What does this tell us? Well for me it tells us that around a quarter of Maine Coon cats develop hip dysplasia (Feline Hip Dysplasia - FHD) anywhere in the world. The same genetic problems exist in all these regions. The breeders are making the same errors in all countries. It is possible to stop the inheritance of FHD; you remove foundation breeding cats from the blood line if they carry the genetic mutation which produces offspring with the disease. But the breeders won't do it because it would change the cats' appearance detrimentally as per the breed guidelines (the standard). Here is a quote from the study mentioned which is: "Demographics of hip dysplasia in the Maine Coon cat". The overall prevalence of FHD was 24.9% (635/2548), and was slightly higher in males (279/1023 [27.3%]) than females (356/1525 [23.3%]) (P = 0.025)....

Demographics of hip dysplasia in the Maine Coon cat

-
Image
In the world of purebred cats, the Maine completely dominates in suffering from hip dysplasia. No other breed or non-breed comes near in terms of prevalence. The right hip is more likely to be diseased compared to the left. The disease can make Maine Coons aggressive and lose interest in human attention (presumed due to the persistent discomfort) which is sad as this cat is calm and friendly when healthy and well cared for. The disease was first mentioned in 1974. This article sets out information about a large number of Maine Coon cats which suffer from hip dysplasia. I will present the information in bullet form below: There were 2732 individual cat participating in this study of which 99.9% were Maine Coons (2708). The youngest Maine Coon cat with feline hip dysplasia (FHD) was four months of age. The oldest was 60 months of age. Of the 2708 Maine Coon cats with hip dysplasia, 2548 had non-borderline symptoms which meant it was full-blown hip dysplasia. Hip dysplasia was more common...

2 reasons why female Maine Coons are better than males

-
Image
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. Image: MikeB 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 mo...

Maine Coon broke 2 hips in 2 weeks. The breed is susceptible to Perthes disease.

-
Image
We know that Maine Coon cats are predisposed through inheritance to develop hip dysplasia. It is a major problem with this breed. However, there is another but slightly different hip disease called Perthes disease. It is also called 'Legg-Calvé-Perthes Disease'. It is a hereditary disease and it affects humans as well. It affects children.  Maine Coon broke his hip twice in 2 weeks. They are susceptible to Perthes disease. This is the cat. Sad. I hope he improves after surgery. Image: Reddit.com. If the blood supply is cut off to the hip joint which describes what happens in Perthes disease, the head of the femur which goes into the socket of the hip degenerates and the bone dies as does the surrounding cartilage. The joint can't function anymore because of the misshapen femoral head and this is, as mentioned, Perthes disease. Like I said, it is very similar to hip dysplasia. As I understand it, they are to different diseases however but the symptoms are going to be similar...

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 . Maine Coon selectively breed to have an extreme face. Image in the public domain. And the Maine Coon is meant to be a large cat, the largest domestic cat b...

Maine Coon Size - this is a huge one!

-
Image
  Enormous Maine Coon with a head bigger than the person holding him. Pic: in public domain. Maine Coon size is very important to both breeders of this cat and the public. I sometimes think that the public is more obsessed with Maine Coon size than the breeders are. The bigger the Maine Coon the better. There is a fascination about it and I confess that there is nothing much more impressive than a huge Maine Coon. They've been bred like this through selective breeding but please remember that they weren't always like this. The original Maine Coons were regular farm cats in the state of Maine in 19th-century and before. They were robust, rugged, medium-longhaired moggy cats but impressive nonetheless. Their impressiveness led to breeders deciding to breed them which in turn led to the breed being accepted by the cat associations and then to win cat shows and become perhaps one of the most famous breeds in the world. The breed standard for the Maine Coon as provided by e.g. Cat F...

Average lifespan of Maine Coon cat

-
Image
How long do Maine Coon cats live for? What's the average lifespan? Do they live shorter lives than the average random-bred family cat? These are difficult questions to answer accurately. In fact, I don't think we can answer them accurately because nobody has been counting. Nobody has a database or carried out a full-blown survey and therefore you will read anecdotal evidence i.e. statements by breeders or people who think they know the answer and these answers get repeated on the Internet. I am not sure that they are accurate. Picture of a Maine Coon who looks like a middle-aged man. Photo: Pinterest. My research indicates that people believe that Maine Coon cats live between about 10 and 15 years old. Some may live longer than that and some may live shorter lives. One well-known Maine Coon, Rubble, lived for 31 years and was at one time the oldest domestic cat in the world. But there will always be exceptions and this article is about the mean or the average although these ...

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...

Are Maine Coons illegal in some countries, states or territories?

-
Image
One Maine Coon website asks if Maine Coons are legal? My initial response was that it is a bizarre question (second thoughts below), but I'll answer it in my way. I say that it is a bizarre question because the Maine Coon is an entirely domestic cat by which I mean NOT a wild cat hybrid and therefore there is no reason whatsoever to declare it illegal in any jurisdiction unless that there is some other fanciful reason to ban the cat (there might be - see below). Are Maine Coons illegal in some countries, states or territories? No, to the best of my knowledge. Image: MikeB I know of no jurisdiction anywhere in the world that bans Maine Coons which makes sense. Conversely a similar sized domestic cat, the F1-F2 Savannah, is illegal in many jurisdictions (states, territories and countries) because it is a wildcat hybrid. The cat has some wild cat DNA which some legislatures consider to be detrimental to human health and welfare and to the conservation of wildlife (if the cat escapes t...

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.

Tortoiseshell Maine Coon with split-face

-
Image
Maine Coon with "split face". Photo: Screenshot. This is a very impressive Maine Coon. As you can see she is a tortoiseshell and as you probably know almost all tortoiseshell and calico cats are female. There are a few male tortoiseshell cats (and this might be one of them). Their sex is caused by a genetic aberration because the genetics of tortoiseshell cats dictates that they are almost always female. About one in 3000 are male as I recall. Also, it is not that unusual to see this extreme pattern on the face which creates the appearance of a "split-face". This is not what is called a "chimera" but a normal variation of the tortoiseshell pattern. Sometimes you do see what some people call "two-faced" cats with this sort of face due to a sharply defined pattern down the middle of the face. But the genetics behind that is different to this normal tortoiseshell variation. This is a particularly extraordinary looking Maine Coon cat. Not all Maine C...

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.

A mightily beautiful orange Maine Coon

-
Image
Orange cats seem to feature in films more than other types of domestic cat . Is it because they have good, balanced characters? I am discussing the possibility of a link between coat type and color and character. A big call. A longshot. But possible. I discussed it in another post - click here if it interests you .  So, we love orange cats. They are undoubtedly one of the more popular cat coat types. And that is one reason why this Maine Coon is so damned attractive. What a combination: the size and presence of the Maine Coon, the world's largest domestic cat breed , and the orange tabby coat ( the friendliest cats? ) A mightily beautiful orange Maine Coon. Photo: Pinterest. I think this sort of domestic cat is the most desirable. You would be hard pressed to adopt a better cat but the best ones to adopt are the unadoptable, elderly, black rescue cats languishing in a shelter somewhere . A bit about the orange cat Cat breeders tend to refer to orange as red. The general public r...

Today's Maine Coons are much larger and longer than the original

-
Image
There was a time, during the early years when the Maine Coon's popularity was in decline that the cat fanciers struggled with writing what they believed to be the correct breed standard. There was competition between what Richard H Gebhardt describes as a "progressive standard" or one which was designed to "describe and preserve an existing cat" i.e. fix the appearance. At this time this cat breed was much more a standard looking cat which is probably why it failed to catch the imagination of the cat loving public of America. Maine Coon. Photo in public domain. A progressive standard is one which allows breeders to constantly "refine" the appearance as they might describe it. But this can lead to extreme breeding and extreme appearances such as is evident in the Persian and Siamese. There was a time, then, went Richard H Gebhardt says that cat fanciers asked, "is the Maine Coon cat simply the long-haired variety of the domestic, or American, sh...
