Maine Coon Cats: Health Problems to Beware

The Maine Coon cat is one of the oldest natural breeds in North America and generally regarded as a native of Maine. They are able to adapt to environments with harsh and very cold climates because of their long-haired, heavy and water-resistant coats.

As for their temperament, they are sociable creatures that prefer to stay close by their owner observing their activities. They are also playful and active, and get along well with children, dogs and other cats.

Although they are easy to manage, Maine Coon cats can pose some concern for their owners, particularly when it comes to their health. These cats are prone to some medical conditions that can be quite serious if prompt attention and treatment are not provided.

Learn more about the common Maine Coon cats health problems, and get some tips on how to handle each disorder.

Hypertrophic Cardimyopathy (HCM)

Commonly termed as a "silent killer" because it is difficult to diagnose, this heart disease is usually present in Maine Coon cats, particularly in adult and male cats of this breed.

HCM occurs when the muscle walls of a cat's heart thickens, which causes the heart to pump less efficiently. This disorder can progress or worsen rapidly even without medication.

A complication of this heart disease can lead to congenital heart failure, a build-up of fluid around the heart and the lungs, and a blood clot that blocks the flow of blood to the hind legs, thus resulting in paralysis.

Although symptoms do not typically occur, these warning signs may be experienced:

  • Shallow breathing
  • Paralysis
  • Lethargy
  • Coughing
  • Severe weight loss

Cats that experience these symptoms should be given prompt medical attention. An echocardiogram is the only means of detecting and diagnosing HCM. If an HCM is proven to be present, beta-blockers, diuretics and ACE inhibitors may be prescribed as treatments.

Hip Dysplasia

Hip dysplasia, which is another of the common Maine Coon cat health problems, is a genetic defect where the hip joint develops abnormally.

This occurs when the hip joint does not fit well into the hip socket.

Eventually, the hip joint becomes damaged because of the constant knocking of the femur head against the socket.

As the cat ages, this can lead to osteoarthritis, which is a degenerative joint disease.

This health condition can occur in cats of different ages, and the most common signs of hip dysplasia are stiffness when walking, reluctance to jump or run, and lameness.

Although it is not fatal, it can be very painful to cats. In fact, hip dysplasia can be crippling when proper treatment and therapy are not given.

To prevent further damage to the hip joint, cats are put on a weight management diet. Extra weight can add pressure on the hips, thus worsening its condition.

There are also certain exercises that a veterinarian may recommend as therapy such as walking on a leash, walking on a treadmill, and going up and down the stairs.

Proper massages can also help alleviate the pains, as well as keep the cat warm, since the cold weather can induce arthritis. In addition, the veterinarian may also prescribe medications to treat this health condition such as NSAIDs, glucosamine and vitamin C.

Polycystic Kidney Disease

Polycystic Kidney Disease, or PKD, is a genetic disease in Maine Coon cats where small cysts in the kidneys develop.

The cysts are present at birth, and they multiply and grow in size as the cat ages.

As the cysts develop, they tend to replace normal kidney tissue. The kidneys increase in size, and this leads to a decline in the renal function. A complication of this illness is chronic renal failure.

Because this disorder progresses slowly, a cat suffering from it may not show symptoms. Normally, warning signs are evident when a cat is already an adult or about seven years of age.

Be alert for any of the following:

  • Lethargy
  • Frequent urination
  • Loss of appetite
  • Vomiting
  • Increased thirst
  • Weight loss

To diagnose PKD, a genetic test and ultrasound may be recommended by a veterinarian. Although there are no means of slowing down and removing the cysts in the kidneys, therapy may be recommended such as medication and a prescribed diet.

An ideal diet for cats with PKD includes foods with low protein but less phosphorus content than normal cat food. Since a damaged kidney is not able to remove phosphorus from the blood, cats suffering from this disorder need to control their intake of this mineral.

Hormone therapy such as erythropoietin may also be advised. This particular hormone enables the bone marrow to produce red blood cells. Kidney failure in cats results in a decreased production of red blood cells, thus it is important for cats to have this hormone to normalize the levels of red blood cells.

Maine Coon cats are typically healthy cats, but they are susceptible to certain diseases that can be serious and even life-threatening. However, with prompt treatment, proper medication, and an appropriate diet, the discomfort brought about by these disorders can be alleviated. Monitoring your cat's activity and overall appearance in combination with regular visits to your veterinarian are the best ways to keep your cat health and happy for its lifetime.
