Diabetes Mellitus in Cats Symptoms and Treatment

What is diabetes mellitus?

Diabetes mellitus in cats is a complex metabolic disorder characterized by an inability of the body to regulate blood sugar levels properly due to insufficient insulin production or poor response to insulin. Insulin, produced by the pancreas, is crucial for regulating glucose metabolism and maintaining stable blood sugar levels. When this balance is disrupted, it leads to diabetes mellitus. This illness can be present in any cat breed from American long hair, to American Short hair, and even the beautiful Ragdoll.

Symptoms of diabetes mellitus in cats can manifest gradually and may include:

  • Increased Thirst (Polydipsia): Cats will drink more water than usual due to the body’s attempt to eliminate excess glucose through urine, leading to dehydration.
  • Frequent Urination (Polyuria): Excessive urination occurs as the kidneys work to eliminate the excess glucose in the urine.
  • Increased Appetite (Polyphagia): Cats may exhibit a heightened appetite despite losing weight. The body’s cells are unable to utilize glucose properly for energy, leading to a constant feeling of hunger.
  • Weight Loss: Despite an increased appetite, cats may lose weight due to the breakdown of body fat and muscle tissue for energy.
  • Lethargy and Weakness: A cat’s overall energy levels may decrease, leading to reduced activity and increased sleepiness.
  • Vomiting or Dehydration: In severe cases or if left untreated, diabetes mellitus can lead to vomiting, weakness, and dehydration.

Diagnosis of diabetes mellitus in cats involves a combination of clinical signs, blood tests to measure blood glucose levels, and urine tests to check for the presence of glucose and ketones. Sometimes, further tests like fructosamine or glycated hemoglobin tests are performed to assess the average blood sugar levels over a few weeks.

Once diagnosed, the treatment of diabetes mellitus in cats primarily revolves around managing blood sugar levels and supporting overall health. Treatment options include:

Insulin Therapy: Most diabetic cats require insulin injections to help regulate their blood sugar levels. Your veterinarian will determine the appropriate type and dosage of insulin based on the cat’s needs. It’s essential to administer insulin as prescribed and monitor blood sugar levels regularly.

Dietary Management: Feeding a consistent, high-protein, low-carbohydrate diet prescribed by the veterinarian can help regulate blood sugar levels. Specialized diabetic cat foods are available and can aid in managing the condition.

Weight Management and Exercise: Cat obesity is the main cause for developing diabetes. Maintaining a healthy weight through portion control and encouraging regular exercise can help manage diabetes mellitus. However, exercise should be regulated and monitored to prevent hypoglycemia (low blood sugar).

Monitoring and Regular Veterinary Check-ups: Monitoring blood glucose levels at home (if recommended by the vet) and regular check-ups are crucial to assess the cat’s response to treatment, adjust insulin doses if necessary, and address any complications or changes in health.

It’s important to note that while diabetes mellitus in cats is a manageable condition, it requires dedicated care and ongoing monitoring. Some diabetic cats may go into remission, where they no longer require insulin therapy due to improved insulin sensitivity. However, remission is not guaranteed, and lifelong management may still be necessary.

Untreated or poorly managed diabetes mellitus can lead to severe complications, including diabetic ketoacidosis (DKA), a life-threatening condition characterized by extremely high blood sugar levels, dehydration, and electrolyte imbalances.

Owners of diabetic cats should work closely with their veterinarians to develop a comprehensive treatment plan tailored to their cat’s specific needs. With proper management, including insulin therapy, diet control, and regular monitoring, diabetic cats can lead happy, comfortable lives.
