Factors That Might Shorten The Lifespan Of Maine Coons


It is necessary to understand that Maine Coons were originally field cats.

Their build was intended to keep them strong and quick to work effectively in farms and barns.

They require regular exercise to control their weight. The average weight of a Maine Coon is 10 to 17 pounds.

Many owners desire to give their cats a chubby, pillow-like appearance. However, this could prove unhealthy for your Maine Coon and could create health problems like obesity.

Improper Diet

Although Maine Coons do not have special dietary needs, certain things if included in the diet can reduce their lifespan in the long run.

Grain-based food should be avoided as a large part of the diet since it can contribute to unhealthy weight gain.

Anything with wheat should also be off the charts since it contains gluten which is not healthy for the digestive tract.

It is advised that an expert should be consulted to decide a suitable diet for your Maine Coon.

Maine Coons require a high protein diet as they continue growing for up to 5 years after birth. If other cats are in the household then a lower protein diet can typically be fed to them.

Genetic Disorders

Maine Coons are plagued with some general disorders (with respect to other breeds) that might shorten their life expectancy.

Buying a Maine Coon from a breeder can help eliminate this problem, as genetic disorders can be bred out.

Most common of them being arthritis. Although it is common in many cats and dog breeds, if left unchecked, it can lead to paralysis.

Maine Coons are also prone to spinal muscular atrophy genetically.

This causes the muscles to weaken. This condition can be diagnosed earliest when the kitten is 3 weeks old.

This severely shortens the lifespan of the Maine Coon.

How To Increase The Lifespan Of Your Maine Coon

With proper care and attention, Maine Coons are known to live for as long as 15 years, and as alluded to earlier, treated well they can live a great many years without issue.

Proper Diet

A Maine Coon is tolerant to most foods so, you do not need to fret much.

However, basic care should be taken in order to ensure good health of your pet.

A fat-free cat food is preferable in most domestic settings. If you opt for a food with more fat content, make sure that you give them enough exercise to avoid excess weight gain.

Also, insist on dry food and wet food variety to go easy on their stomach.

Animal based protein diets are best as they are protein rich. So chicken, beef, turkey and other meets like fish help keep their health up.

I will add here, that m Maine Coon is named Alita and she is allergic to chicken, as we have recently found out.

If your Maine Coon isn’t putting on the weight and is a bit too skinny, then consider a quick diet change to see if the effect reduces.

Plenty Of Exercises

Maine Coons do not need much encouragement for playtime.

They retain their energetic kitten spirit well into their adulthood.

They require a fixed amount of exercise every day to stay healthy.

A great way for this is to indulge them in a playful activity like fetch. This exercise is important as it keeps them healthy and helps to create a bond of camaraderie with their owners.

Regular Health Checkups

Regular visits to a vet are must for the well being of not just Maine Coons but any pet.

It is important to keep your pet vaccinated.

Also, regular checkups might be useful to detect underlying diseases or complications early on to decide preventive measures.

Common Diseases Maine Coons Are Prone To

Hip Dysplasia– This is a genetic disorder more prone in Maine Coons which causes the hip joint to develop abnormally.

As a result, the femur doesn’t fit normally into the socket but instead rams against it during every movement. In the long run, it can lead to degeneration of joints and arthritis.

Although the condition is not fatal, it can cause great pain and discomfort to the cat. The vet may prescribe a weight loss regime or regular exercise to alleviate the pain.

Polycystic Kidney Disease – This is a disease which does not show any symptoms at its early stage.

Cats suffering from PKD might start showing the symptoms at adulthood when the disease has already taken form.

Symptoms include lethargy, loss of appetite, frequent urination, vomiting, increased thirst sensation and weight loss caused due to development of cysts in kidneys.

These cysts later start replacing the kidney tissue and increase the size of the kidney.

If left unchecked, it may lead to kidney failure. As of now, no treatment is available to remove the cysts. A diet low on fat with plenty of available water to keep the kidney healthy is advised.

Hypertrophic Cardiomyopathy – This is the most dangerous condition a Maine Coon may fall victim to.

Male cats are more prone to this condition than females.

This causes thickening of walls around the heart which makes it pump blood less efficiently. If left unchecked, it can create a complication of congenital heart failure.

This means deposition of fluid around heart and lungs. Symptoms include shallow breathing, severe weight loss, lethargy, coughing, and paralysis.

If one or more of these warning signs are present, your cat needs immediate diagnosis and attention.

If diagnosed, the treatment includes the prescription of diuretics as well as ACE inhibitors, beta blockers etc.


Maine Coons are known for being the most affectionate breed of cats.

Just like a dog, they can develop a deep bond with their owners.

They need constant care and attention.

They miss their owners when they are away and can’t take it well to be left alone for longer periods. They will wait for you when you are away and jump with excitement when you come back.

With a Maine Coon, you can get numerous years of love and companionship.
