Big Maine Coon Cat

The big Maine Coon cat (MC) is very impressive and the biggest purely domestic cat in the world (I am excluding the wildcat hybrids) but not all Maine Coons are huge. The MC is also the largest native American purebred cat. I suppose that is obvious. Sometimes people think that Maine Coons weight 30-40 lbs (13.5 to 18 kgs). This is not true. One breeder says that the average female MC weighs between 8-12 pounds and males weigh up to 18 pounds. These are cats in good condition. Obviously fat MCs are going to weigh 25 lbs sometimes. The shaggy fur covering a long lean body probably adds to the impression of size. Also when you compare them with some of the svelte, slender and slight modern oriental style cats they look enormous. I am thinking of the Oriental Shorthair for example.

That said the Maine Coon below has a head which is similar in size to the head of the person carrying him - there are some huge Maine Coons:



It can take 4-5 years for an MC to reach maximum size. The factors that dictate size are genetics (selective breeding probably played a part here too), diet and exercise! Intact males (not neutered) are more likely to achieve higher weights in meeting the cat's full potential due to the contribution of the cat's hormones to his development. By contrast a male cat that is breeding may have reduced coat density making him look smaller.

Other than selective breeding since the late 1800s to the present (the duration of the cat fancy) what makes the Maine Coon so big? Well this cat is not as big as people think as mentioned. Secondly, if the Maine Coon originates in ships cats imported from Europe about 400 years ago, these cats were probably large in the first place and then they developed/evolved naturally as farm cats. The farm cat/mouser lifestyle probably lead to the natural selection of larger cats.

Jordy the 5 year old Maine Coon above, full name: Nascat Jordache of Coonoquan was featured in the Atlanta Magazine in 2007. Does be look a little bit overweight? Apparently he has a very laid back character and looks regal. He does look docile and well mannered in this picture.

Photo above: The judge said the cat "unfolds" indicating that Maine Coons are long and flexible more than simply big. Many breeders testify to their MCs being 5 feet from nose to tail (about 1.5 meters).

very large Maine Coon cat

Photo above: His name is Shooter. I think he is the biggest Maine Coon I've seen - photo is copyright wendyophoto - this is a very impressive photograph. Wendy says, "This HDR was made from a single RAW photo taken at ISO 1600". See this image in large format. See also a lot of Maine Coon cats and great information.

There is a certain fascination with big animals including cats. In the UK there is the perennial sighting of the escaped big cat roaming around some parkland or farmland in the dusk. We never see evidence other than a poor quality picture. There are supposed to be dozens of wild beasts in England and someone I recall is setting up remote cameras to try and get that elusive evidence. Some think they might be large feral domestic cats. People do tend to exaggerate what they have seen.

In the same vein there is a fascination about the Maine Coon cat's size. We know that this breed can throw up some big cats but they are not all that big normally. And in any event if we are to compare cat breeds we should look at the average weight of male and female cats of each cat breed. The averages are much less than the one off large male.

All that said the Maine Coon is the largest cat breed if you're talking about CFA registered purebred cats. TICA register more cats and some are wild cat/domestic cat hybrids such as the Savannah and an F1 or F2 Savannah is bigger than a Maine Coon normally. The world's tallest "pet cat" was Magic an F1 Savannah of great presence.

You'll get some oddities caused by an illness and you'll get some very fat cats, one is illustrated on this page. These are larger than normal but not for the right reasons. It is, I feel, rather pointless to isolate large domestic cats that are large because they are overweight or ill. Worse it is a kind of freak show.

One classic way of breeding larger domestic cats is through hybridization with wildcats as they are sometimes but not always larger than domestic cats. In fact I made a comparison between the large domestic cats and wild cats on the page linked to above. The Savannah is the classic large domestic cat/wildcat hybrid at F1-2 level. The thing is, it is impractical to have domestic cats that are large beyond a certain threshold as keeping them requires special arrangements. In addition breeders need to breed the wildcat hybrids back to domestic cats for character. You can't really live with a wild cat in the house. This automatically reduces the size of the cat.

Abnormally large domestic cats of any breed including the Maine Coon is unlikely to happen because selective breeding over the years has dramatically narrowed the gene pool. Purebred cats often have a high Coefficient of Inbreeding as breeders search for the perfect appearance. This limits the occurrence of oddities in regards to size.

Apparently a Maine Coon has been 49 inches in length, that is about 4 feet. The world's longest domestic cat (now deceased sadly and he died young) was Stewie a Maine Coon at 48 and one half of an inch. Maine Coon cats are actually long rather than purely big. So a big Maine Coon cat will be very long and this is amply demonstrated in the pictures.

One last thing, photographic evidence requires some sort of scale to compare size with. A very big Maine Coon cat would look small against a very large person. And similarly you cannot tell a big Maine Coon cat from a photograph unless there is something in the picture to compare size with. There are also a number of hoax photographs on the internet. These are photographs manipulated using Photo shop type software.

Each picture on this page have been selected as showing a big Maine Coon cat with something to scale by (except for Jordy! but his weight is recorded as correct). It is for that reason I am showing people where possible as well as cats in the photograph.

These cats are big-boned - you can see that from the size of their lower legs compared with an ordinary "moggy". But there is no excuse for letting a cat get seriously fat. It is animal abuse just as bad as not feeding an animal enough. It's not clever or funny in any way.

Having said that, Maine Coons are just the best cats. A well-socialised Maine Coon is a delight - and I've had lots of cats in my life.

The cat was not fat. A normal sized, heathly, happay Maine Coon. Very patient owner who must really love an understand cats. Made me smile .

Cat Ear Mites

Brown gunge. Yes, I know this is a ferret! It does show the build up of dark brown to black ear wax caused by the presence of the cat ear mites in the outer ear canal. This parasite is not restricted to the domestic cat, which makes this photo valid and a useful illustration (I was unable to find a suitable photo of a cat with the condition). Photo Stacy Lynn Baum under a creative commons license. Ear mites (minute crab like creatures) are one of the causes of inflammation of the outer ear canal (scientific term for this inflammation is Otitis externa ). The outer ear canal is the tube that runs from outside to the ear drum (the pathway for the reception of sound), which can be seen when looking at the ear. Otitis externa affects humans and often swimmers as it is called "swimmer's ear" in humans. This YouTube video show ear mites under a microscope. They are not actually in the ear in this video. There are many possible causes of Otitis externa in c

Feline Mange

I'll write about three types of feline mange (a) feline scabies or head mange (b) demodectic mange and (c) sarcoptic mange. The source material is from Cat Owner's Home Veterinary Handbook - the best on the market . Generalised feline mange? Puerto Rico - Photo by Gotham City Lost And Found Feline Scabies - head mange Head mange or feline scabies, is a fairly rare condition in cats, which is caused by the Notoedres mite (head mite) that only reproduces on cats. The female mites burrow a few millimeters (that is a lot) into the skin around the head, and neck to lay eggs, which hatch and lay their own eggs. Their presence and activities causes intense itching that in turn causes the cat to scratch. The scratching will obviously be noticed and it will cause the skin to become red, scratched and worse infected. Symptoms: hair loss and scabs, thick wrinkled skin and grey/yellow crusts form plus the symptoms of scratching. Feline mange (head mange) is contagious and tr

Cat Anatomy

Cat Anatomy - Photo by Curious Expeditions . The picture above was taken at Wax Anatomical Models at La Specola in Florence, Italy. The photograph is published under a creative commons license kindly granted by the photographer. I am sorry if it is a bit gruesome. It is pretty well all I could find as an illustration that was licensed for publication. Cat Anatomy is a very wide ranging subject. The anatomy of a cat is very similar to human anatomy. If you were writing a biology book for students of biology you would go through every part of the a cat's anatomy in some detail. It would be similar to writing a book about the human anatomy. It would be a thick book and pretty boring for your average internet surfer. So, how do you limit such a big subject and make this post meaningful? The answer I think lies in doing two things: Having a quick general look at cat anatomy - an overview and; Focusing on the areas of cat anatomy that are particular to the cat and of parti
