Understanding Addison’s Disease in Cats
Addison’s disease, also known as hypoadrenocorticism, is a potentially life-threatening disorder that affects cats. It is characterized by an inadequate amount of hormones produced by the adrenal glands, two small glands located just in front of the feline’s kidneys. This deficiency in hormone production can have significant impacts on the cat’s overall health and well-being.
Overview of Addison’s Disease
Addison’s disease in cats is relatively rare but should be considered a medical emergency due to its potential impact on vital systems. The disease occurs when the immune system, which normally protects the body from illness, begins to attack and destroy the tissues of the adrenal glands. This destruction leads to a deficient production of hormones that are essential for the healthy functioning of many body systems.
The clinical signs of Addison’s disease in cats are usually noted within days of damage to the adrenal glands, although symptoms can also appear over a monthly period. The cause of Addison’s disease in cats is still unknown, but it may be linked to an autoimmune condition where the immune system mistakenly attacks the adrenal glands, or it could be triggered by sudden withdrawal of steroid therapy.
Causes of Addison’s Disease
The exact cause of Addison’s disease in cats remains unclear, but there are several potential factors that may contribute to its development. While the disease does not seem to be associated with any specific breed or age, it may be linked to an autoimmune condition where the immune system mistakenly attacks the adrenal glands. Additionally, sudden withdrawal of steroid therapy can also be a trigger for the development of Addison’s disease in cats (PetMD).
Understanding the underlying causes of Addison’s disease is essential for accurate diagnosis and effective treatment. If you suspect your cat may be experiencing symptoms of Addison’s disease, it is crucial to consult with a veterinarian for proper evaluation and diagnosis.

Recognizing Symptoms in Cats
Addison’s disease, also known as hypoadrenocorticism, is a rare but serious condition that can affect cats. Recognizing the symptoms of Addison’s disease is crucial for early diagnosis and treatment. In this section, we will explore the common signs and symptoms of Addison’s disease in cats, as well as the diagnostic process involved.
Common Signs and Symptoms
Symptoms of Addison’s disease in cats can vary but may include:
- Decreased appetite and weight loss
- Malaise and weakness
- Dehydration
- Slow capillary refill time
- Low blood pressure
- Vomiting
- Hypothermia
- Diarrhea (rarely observed in cats) (PetMD)
Cats with hypoadrenocorticism may exhibit waxing and waning periods of lethargy, decreased appetite, weight loss, and vomiting episodes. Physical examination may reveal signs of dehydration, weakness, slow heart rate, and loss of body fat and muscle mass. In severe cases, cats may present in shock with weak pulses, severe dehydration, and extreme weakness. It’s important to note that symptoms can vary among cats, and not all cats will exhibit all of these signs.
Diagnostic Process for Addison’s Disease
Diagnosing Addison’s disease in cats requires a thorough veterinary evaluation. The diagnostic process typically involves a combination of medical history, physical examination, and laboratory tests. Your veterinarian may perform the following diagnostic procedures:
- Blood tests: These tests can help evaluate the levels of electrolytes, such as sodium and potassium, which are often imbalanced in cats with Addison’s disease. Cats with primary hypoadrenocorticism may show electrolyte changes characteristic of mineralocorticoid deficiency, including hyponatremia, hypochloremia, hyperkalemia, mild to severe azotemia, and hyperphosphatemia.
- Diagnostic tools: Additional tests, such as an adrenocorticotropic hormone (ACTH) stimulation test, can help confirm the diagnosis of Addison’s disease in cats. This test measures the response of the adrenal glands to ACTH, a hormone that stimulates the production of cortisol.
It’s crucial to consult with a veterinarian if you suspect your cat may have Addison’s disease. Prompt diagnosis and treatment can help manage the condition effectively.

Diagnosis and Treatment
When it comes to feline Addison’s disease, prompt diagnosis and appropriate treatment are essential for managing this condition effectively. In this section, we will explore the diagnostic procedures and treatment approaches commonly employed for feline Addison’s disease.
Blood Tests and Diagnostic Tools
Diagnosing Addison’s disease in cats involves various blood tests and diagnostic tools. A key test for diagnosing this condition is the ACTH (adrenocorticotropic hormone) stimulation test. This test evaluates adrenal function by measuring cortisol levels before and after administering synthetic ACTH. Cats with Addison’s disease tend to show minimal to no increase in cortisol levels during the test. It’s crucial for a definitive diagnosis.
In addition to the ACTH stimulation test, other blood tests are performed to assess the feline’s overall health and identify any abnormalities that could link their condition to Addison’s disease. These tests may include a complete blood cell count (CBC) to check for anemia, changes in white blood cell patterns, and increased eosinophils. Blood tests also look for elevated blood urea nitrogen (BUN), increased phosphorus levels, and electrolyte imbalances (PetMD). These tests help to paint a comprehensive picture of the feline’s health and aid in making an accurate diagnosis.
Additional diagnostic tools that may be used include urinalysis, blood pressure monitoring, chest X-rays, and electrocardiography (ECG). These tests provide valuable insights into the feline’s overall health and can help determine the impact of Addison’s disease on vital systems (PetMD).
Treatment Approaches and Medications
Once a diagnosis of Addison’s disease is confirmed, treatment typically involves hormone replacement therapy. Cats with Addison’s disease require lifelong administration of glucocorticoids (such as prednisolone) and mineralocorticoids (such as fludrocortisone) to compensate for the hormonal deficiencies caused by this condition (VCA Canada). These medications help to regulate the body’s hormone levels and manage the symptoms associated with the disease.
It’s important to work closely with a veterinarian to determine the appropriate dosage and frequency of administration for these medications. Regular monitoring of the cat’s hormone levels, electrolyte balance, and overall health is crucial to ensure the treatment is effective and adjustments can be made as needed (VCA Canada).
