Understanding Addison’s Disease in Cats
Addison’s disease, also known as hypoadrenocorticism, is a rare condition that affects the adrenal glands in cats. These glands are responsible for producing vital hormones, such as cortisol, which play a crucial role in the body’s various systems. When the adrenal glands don’t function properly, it can have a significant impact on a cat’s health.
Overview of Addison’s Disease
Addison’s disease in cats is characterized by a deficiency of adrenal gland hormones, including glucocorticoids, mineralocorticoids, and sexual function hormones. The condition is relatively rare but should be considered a medical emergency due to its potential to disrupt vital systems in the body. Symptoms of Addison’s disease in cats can include decreased appetite, weight loss, malaise, weakness, dehydration, slow capillary refill time, low blood pressure, vomiting, hypothermia, and diarrhea.
Impact on Adrenal Glands
The adrenal glands, located near the kidneys, produce hormones that are essential for the healthy functioning of the body. These hormones assist in regulating electrolyte balance, managing stress responses, and supporting various metabolic processes. In cats with Addison’s disease, the adrenal glands don’t produce enough of these hormones (PetMD).
The underlying causes of Addison’s disease in cats can vary. It is believed to be associated with an autoimmune disorder, where the cat’s immune system mistakenly attacks its own tissue, including the adrenal glands. Other potential causes can include factors like cancer or injury to the glands (Catster).
Understanding the intricacies of Addison’s disease in cats is crucial for prompt diagnosis and appropriate treatment. In the following sections, we will explore the symptoms, diagnostic methods, causes, and management strategies for feline Addison’s disease.

Diagnosing Addison’s Disease
To accurately diagnose Addison’s disease in cats, veterinarians rely on specific tests to assess adrenal function and determine the presence of this condition. Two commonly used diagnostic tests for Addison’s disease are blood tests and the ACTH stimulation test.
Blood Tests for Diagnosis
Blood tests play a crucial role in diagnosing Addison’s disease in cats. These tests help evaluate various parameters that can indicate the presence of the condition. A complete blood cell count (CBC) may be performed to check for anemia, changes in white blood cell patterns, and an increase in eosinophils. Additionally, blood urea nitrogen (BUN), phosphorus, and electrolyte levels are assessed to identify any imbalances.
ACTH Stimulation Test
The ACTH (adrenocorticotropic hormone) stimulation test is a key diagnostic tool used to confirm the presence of Addison’s disease in cats. This test evaluates adrenal function by measuring cortisol levels before and after the administration of synthetic ACTH. Synthetic ACTH stimulates the adrenal glands, causing them to produce cortisol. In cats with Addison’s disease, there is minimal to no increase in cortisol levels after the administration of synthetic ACTH, indicating adrenal insufficiency (PetMD).
During the ACTH stimulation test, two blood samples are taken from the cat: one before the injection of synthetic ACTH and another after a specific time period. The cortisol levels in these blood samples are measured and compared to assess the response. A lack of response to synthetic ACTH administration confirms the diagnosis of Addison’s disease in cats.
It’s worth noting that the ACTH stimulation test is a specialized diagnostic tool and should be conducted by a veterinarian experienced in diagnosing and managing Addison’s disease in cats. This test provides valuable information about adrenal function and helps guide appropriate treatment decisions.
By utilizing blood tests and the ACTH stimulation test, veterinarians can accurately diagnose Addison’s disease in cats. Prompt diagnosis is crucial for timely treatment and management of this condition. Once diagnosed, veterinarians can develop a tailored treatment plan to help cats with Addison’s disease lead healthy and fulfilling lives.

Causes and Risk Factors
Addison’s disease in cats, also known as hypoadrenocorticism, is a rare condition that occurs due to a deficiency in adrenal gland hormones. While the exact cause of this disease in cats is unknown, there are several underlying factors and a potential autoimmune connection to consider.
Underlying Factors
The cause of Addison’s disease in cats remains unclear, but it has been associated with certain underlying factors. One possible cause is an autoimmune condition, where the cat’s immune system mistakenly attacks and destroys the adrenal glands. This immune-mediated destruction can lead to a deficiency in adrenal gland hormones (PetMD). Additionally, other factors like cancer or injury to the adrenal glands may also contribute to the development of the disease.
In some cases, Addison’s disease in cats can be linked to lymphoma or the sudden withdrawal of steroid therapy. However, further research is needed to fully understand the underlying factors that contribute to the development of this condition.
Autoimmune Connection
An autoimmune connection has been suggested in the development of Addison’s disease in cats. It is believed that the cat’s own immune system may mistakenly recognize the adrenal glands as foreign and attack them, leading to their malfunction and hormone deficiency. This autoimmune response can result in the destruction of the adrenal tissue and the subsequent deficiency in cortisol and aldosterone hormones.
The exact mechanisms behind this autoimmune response in cats with Addison’s disease are not yet fully understood. However, ongoing research is focused on unraveling the complexities of the immune system and its role in the development of this condition.
Understanding the potential underlying factors and the autoimmune connection in Addison’s disease is crucial for accurate diagnosis and appropriate management of affected cats. If you suspect your cat may be experiencing symptoms of Addison’s disease, it’s important to consult with a veterinarian for a proper evaluation and diagnosis.

Treatment and Management
When it comes to managing Addison’s disease in cats, a comprehensive treatment plan is essential. Treatment focuses on stabilizing the cat during a crisis and providing long-term medication to maintain hormonal balance. Let’s explore the two main aspects of treatment and management: stabilizing a cat in crisis and establishing a long-term medication regimen.
Stabilizing a Cat in Crisis
When a cat with Addison’s disease experiences an adrenal crisis, immediate medical attention is crucial. Treatment for cats in crisis involves aggressive fluid therapy, electrolyte administration, and steroid replacement therapy. The cat may require hospitalization for close monitoring and intensive care.
Intravenous fluid therapy is administered to correct dehydration and restore electrolyte balance. Electrolyte abnormalities, such as low sodium and high potassium levels, are common in cats with Addison’s disease. By replenishing these electrolytes, the cat’s body can function properly.
Steroid replacement therapy is another vital component of crisis management. Medications like prednisolone, depo-medrol, desoxycorticosterone pivalate (DOCP), or fludrocortisone acetate are used to replace the deficient hormones and stabilize the cat. The specific medication and dosage will be determined by the veterinarian based on the individual cat’s needs.
Long-Term Medication Regimen
After stabilizing the cat during a crisis, long-term management becomes crucial. Cats with primary hypoadrenocorticism require lifetime supplementation of both mineralocorticoids and glucocorticoids.
Fludrocortisone acetate, administered orally at a dose of 0.1 mg per day, or desoxycorticosterone pivalate (DOCP), given as intramuscular injections at a dosage of 10 to 12.5 mg per month, have proven effective in maintaining cats with Addison’s disease (PetMD).
To provide adequate long-term glucocorticoid supplementation, prednisone can be given orally at a dosage of 1.25 mg once a day, or methylprednisolone acetate can be administered as an intramuscular injection at a dosage of 10 mg once a month. These medications help to replace the deficient hormones and maintain hormonal balance in the cat.
Regular follow-up visits with the veterinarian are essential to monitor the cat’s progress and make any necessary adjustments to the medication regimen. With appropriate management and medication, cats with Addison’s disease can have a normal life expectancy.
By stabilizing a cat during a crisis and establishing a long-term medication regimen, owners can provide their feline companions with the necessary support to live a happy and healthy life despite having Addison’s disease. Regular veterinary care and adherence to the prescribed treatment plan are crucial for ensuring the cat’s well-being and long-term health (VCA Hospitals).
Prognosis and Follow-Up
After a diagnosis of Addison’s disease in cats, it is essential to understand the prognosis and the necessary follow-up care for your feline companion.
Veterinary Care Requirements
Cats diagnosed with hypoadrenocorticism, or Addison’s disease, require regular veterinary care and monitoring throughout their lives. Close collaboration with your veterinarian is crucial to ensuring the well-being of your cat.
Follow-up blood tests are typically needed at least once per month initially, with a decrease in frequency over time if the cat responds well to treatment. These tests help evaluate the effectiveness of the prescribed medications and monitor the cat’s hormone levels to ensure they remain within the appropriate range.
In addition to blood tests, regular check-ups with your veterinarian are necessary to assess your cat’s overall health, adjust medications if needed, and address any concerns or changes in your cat’s condition. Your veterinarian will work with you to develop a long-term care plan tailored to your cat’s specific needs.
Monitoring for Lifelong Health
The prognosis for cats with hypoadrenocorticism is generally good if they can be successfully treated during the initial crisis and started on appropriate long-term therapy (VCA Hospitals). When appropriately managed with glucocorticoid and mineralocorticoid supplementation, cats with adrenocortical insufficiency should have a normal life expectancy.
Long-term management of cats with primary hypoadrenocorticism requires lifetime mineralocorticoid and glucocorticoid supplementation. The choice of medication depends on the severity of the condition and the individual cat’s response to treatment. Oral administration of fludrocortisone acetate or intramuscular injections of desoxycorticosterone pivalate have been successful in maintaining cats with Addison’s disease (dvm360).
It is important to adhere to the prescribed medication regimen and follow your veterinarian’s instructions regarding dosage and administration. Regular monitoring, as recommended by your veterinarian, helps ensure that the medications are effectively managing your cat’s condition.
By providing the necessary veterinary care and monitoring, you can help your cat live a happy and healthy life despite the challenges of Addison’s disease. Regular communication with your veterinarian and proactive management are key to maintaining your cat’s well-being.
