Diabetes mellitus in cats is a chronic metabolic disorder characterized by elevated blood sugar levels. This occurs due to an insufficient production of insulin or a reduced ability of the body to respond to insulin.

The most important facts at a glance

Diabetes mellitus in cats is a condition in which blood sugar levels are elevated because either not enough insulin is produced or the body’s cells are resistant to insulin. Type 2 diabetes is more common in cats and is often associated with overweight. Overweight cats are at higher risk because excess fat reduces the insulin sensitivity of the cells. Symptoms can include increased thirst and urination, increased appetite, and weight loss. Blood and urine tests are performed to measure blood sugar levels and detect glucose in the urine for diagnosis. Treatment includes the administration of insulin and a special diet that is low in carbohydrates and high in protein. Regular exercise helps control weight and improve insulin sensitivity. Cats can go into remission if they maintain an appropriate lifestyle, but that is not guaranteed. Prevention focuses on a balanced diet and regular exercise. Research aims to better understand genetic, nutritional, and environmental factors and develop more effective treatment strategies. Regular veterinary check-ups are important to detect early signs of diabetes.

Causes

Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. It allows cells to absorb glucose from the blood and use it as an energy source. In diabetes mellitus, this process is disrupted, leading to persistently high blood sugar levels.

There are two main types of diabetes mellitus in cats: type 1 diabetes, in which the pancreas does not produce enough insulin, and type 2 diabetes, in which the body’s cells become resistant to insulin. Type 2 diabetes is far more common in cats and is often associated with overweight and lack of exercise.

Overweight cats have an increased risk of developing diabetes because excess body fat can reduce the insulin sensitivity of cells. Genetic factors also play a role, and certain breeds such as Burmese cats appear to be more susceptible to developing the disease.

Other risk factors include age, diet, and possibly environmental factors. Older cats are more frequently affected, and a diet high in carbohydrates and low in protein can increase the risk.

Symptoms

Rare symptoms:

The symptoms of diabetes mellitus in cats often develop insidiously and can be easily overlooked. Common signs include increased thirst (polydipsia) and frequent urination (polyuria). These symptoms are the result of the kidneys trying to filter excess sugar from the blood, which leads to increased urine production.

Another common symptom is weight loss despite increased appetite. Cats with diabetes often lose weight because their body cells cannot effectively absorb and use glucose, leading to a breakdown of fat and muscle mass to gain energy.

Other symptoms may include lethargy, a dull coat, and general weakness. In advanced cases, diabetic ketoacidosis, a life-threatening condition that requires immediate medical attention, can occur.

Diagnosis

The diagnosis of diabetes mellitus in cats is based on a combination of clinical symptoms and diagnostic tests. A veterinarian will usually perform a complete clinical examination and order blood and urine tests to determine blood sugar levels and look for signs of glucose in the urine.

An elevated blood sugar level in combination with glucose in the urine is a strong indication of diabetes. Sometimes it may be necessary to measure the fructosamine level in the blood, which represents an average of blood sugar levels over the past few weeks and thus provides a better overview of the cat’s blood sugar levels.

In some cases, additional tests may be required to rule out other diseases that can cause similar symptoms, such as hyperthyroidism or Cushing’s syndrome.

Therapy

The treatment of diabetes mellitus in cats requires careful monitoring and control of blood sugar levels. One of the main methods of treatment is the administration of insulin, which is usually given twice daily in the form of injections. The veterinarian will determine the exact dose and insulin preparation that is best suited for the cat.

In addition to insulin therapy, diet plays a crucial role in the treatment of diabetes. A low-carbohydrate, high-protein diet can help stabilize blood sugar levels and control body weight. It is important to design the cat’s diet in consultation with a veterinarian to ensure that all nutritional needs are met.

Exercise is another important aspect of treatment. Regular physical activity can help control weight and improve insulin sensitivity. The veterinarian can provide recommendations on how to safely and effectively encourage the cat to exercise.

Prognosis and follow-up care

The prognosis for cats with diabetes mellitus can vary and depends on several factors, including the severity of the disease, the response to treatment, and the ability to change the cat’s lifestyle habits. With appropriate treatment and monitoring, many cats can live a happy and fulfilling life.

It is important for cat owners to work closely with their veterinarian to manage the disease effectively. Regular check-ups and adjustments to treatment may be necessary to keep blood sugar levels stable and avoid complications.

Some cats can go into remission, which means they no longer need insulin therapy as long as they maintain an appropriate diet and lifestyle. However, this is not possible for all cats and should not be taken as guaranteed.

Prevention

The prevention of diabetes mellitus in cats focuses on maintaining a healthy lifestyle. A balanced diet is crucial to avoid overweight, as obesity is a significant risk factor for the development of diabetes. It is important to offer a cat a diet that is high in protein and low in carbohydrates, as this can help to keep blood sugar levels stable.

Regular physical activity also plays an important role. Daily play and exercise not only control the cat’s weight but also improve its insulin sensitivity. Cat toys that stimulate hunting instincts can help keep the cat active.

Regular veterinary check-ups are essential to detect early signs of diabetes or other health problems. An annual blood test can help identify changes in blood sugar levels early. Cat owners should pay attention to changes in their cat’s behavior or weight and report them to their veterinarian.

In addition, owners should avoid giving their cat food intended for humans, as this often contains unsuitable nutrient compositions. By observing these preventive measures, the risk of a cat developing diabetes can be significantly reduced.

Outlook on current research

Research on diabetes mellitus in cats has made significant progress in recent years. Scientists are working to better understand the genetic, nutritional, and environmental factors that contribute to the development of this disease. One focus is on identifying specific genes that could make cats more susceptible to diabetes. These genetic studies could lead to targeted breeding programs in the future that reduce the risk of diabetes in certain breeds.

Another important aspect of research is the improvement of treatment strategies. New insulin preparations are being developed that allow for more stable blood sugar control and improve the quality of life of affected cats. In addition, research is being conducted on alternative treatment methods, such as the use of oral medications that increase insulin sensitivity or reduce glucose production by the liver.

Nutritional research also plays a crucial role. Studies are investigating which nutrient compositions are most effective in preventing and treating diabetes in cats. There is evidence that a high-protein and low-carbohydrate diet may be beneficial. Researchers are also testing dietary supplements that can stabilize blood sugar levels.

Another promising area is the study of the microbiota in the intestines of cats. The composition of the intestinal bacteria could play a role in the development and control of diabetes. By understanding these connections, new probiotic or prebiotic treatments could be developed that reduce the risk of diabetes or improve metabolic control.

Overall, research on diabetes mellitus in cats is becoming increasingly interdisciplinary. Veterinarians, geneticists, nutritionists, and microbiologists are working together to paint a more comprehensive picture of the disease and develop new, more effective treatment approaches. These efforts promise to bring significant improvements in the prevention and treatment of diabetes in cats in the near future.
