Diagnosing Kidney Disease in Cats
When it comes to diagnosing kidney disease in cats, veterinarians employ a variety of diagnostic tests to assess kidney function and determine the stage of the disease.
Diagnostic Tests
Routine blood work and urinalysis are crucial for diagnosing kidney disease in cats. These tests focus on specific kidney markers such as blood urea nitrogen (BUN), creatinine, phosphorus, electrolytes, calcium, red and white blood cell counts, symmetric dimethylarginine (SDMA), urine specific gravity, and urine sediment. By evaluating these parameters, veterinarians can gain insight into the overall health of the kidneys and the extent of renal damage.
A newer blood test that has proven to be helpful in the early diagnosis of chronic renal failure in cats is the measurement of symmetric dimethylarginine (SDMA) levels. SDMA concentrations increase before serum creatinine levels rise, enabling veterinarians to intervene at an earlier stage of the disease.
To further evaluate kidney function and identify any underlying causes, additional tests may be conducted. These tests may include measurements of proteins, potassium, phosphorus, calcium, and blood cell counts. Imaging techniques, such as ultrasound, can also be employed to assess the structure and size of the kidneys (VCA Hospitals).
Stages of Kidney Disease
Kidney disease in cats is classified into four stages based on the severity of clinical signs and laboratory values. These stages help veterinarians determine the appropriate treatment plan and prognosis for the cat (PetMD).
The four stages of kidney disease in cats are as follows:
- Stage I: In this stage, cats may not present any apparent clinical signs.
- Stage II: Cats may exhibit some clinical signs at this stage.
- Stage III: Many clinical signs are present, and cats may appear sick.
- Stage IV: The majority of clinical signs are observed, and cats may be in a critical state.
The staging process takes into consideration not only the clinical signs but also laboratory values and overall assessment of the cat’s health. Each stage denotes a different level of severity, and treatment plans are tailored accordingly (PetMD).
By utilizing diagnostic tests and staging criteria, veterinarians can accurately diagnose kidney disease in cats, assess the extent of renal damage, and develop an appropriate treatment plan to manage the condition. Early diagnosis is key in promoting a better quality of life for cats with kidney disease, as it allows for timely intervention and treatment (VCA Hospitals).
Treatment Options for Kidney Disease
When it comes to treating kidney disease in cats, a comprehensive approach is necessary to address the underlying cause and manage the condition effectively. The treatment options for kidney disease in cats typically include medications, specialized diet, and hydration management.
Medications
Medications play a crucial role in managing kidney disease in cats. The specific medications prescribed depend on the underlying cause and stage of the disease.

In some cases, cats with kidney disease may experience dehydration due to increased water loss or decreased water intake. It’s important to ensure that your cat has access to fresh water at all times and encourage regular drinking.
In certain situations, additional hydration management may be necessary. Your veterinarian may recommend subcutaneous fluids, which involve administering fluids under the skin to help hydrate the cat and support kidney function. This procedure is typically done at the veterinary clinic, but with proper training, it can also be done at home.
By utilizing a combination of medications, specialized diet, and hydration management, the treatment plan for kidney disease in cats aims to slow the progression of the disease and improve the cat’s quality of life. Regular monitoring and follow-up visits with your veterinarian are essential to assess the effectiveness of the treatment and make any necessary adjustments to ensure the best possible outcome for your feline companion.
Chronic Kidney Disease in Cats
Chronic kidney disease (CKD) is a progressive condition that affects the kidneys of cats. Early diagnosis of CKD can be challenging, as routine blood and urine tests have limitations in detecting early stages of the disease (PubMed).
Early Diagnosis Challenges
Diagnosing early or non-azotaemic CKD (CKD without abnormal levels of nitrogenous waste products in the blood) is more difficult compared to advanced stages of CKD. Feline CKD is diagnosed based on clinical signs and renal azotaemia, which requires urinalysis, particularly urine specific gravity, to confirm the diagnosis. Simple, inexpensive, and accurate methods for early CKD diagnosis are still under investigation (PubMed).
Techniques currently being studied for early CKD diagnosis in cats include:
- Limited sampling strategies to estimate glomerular filtration rate (GFR)
- Clearance marker cut-off concentrations to identify cats with low GFR
- New indirect GFR markers
- Urinary biomarkers (PubMed)
Early detection of CKD is crucial as it allows for more prolonged survival times and enables timely intervention to slow the progression of the disease.
Associated Complications
As CKD progresses, cats may experience various complications. These complications can include anemia, electrolyte imbalances, high blood pressure, and changes in urinary habits. Monitoring and managing these complications are essential to ensure the well-being of cats with CKD.
To assess the extent of kidney failure and determine appropriate treatment, veterinarians may perform additional tests, such as measuring blood levels of proteins, potassium, phosphorus, calcium, and blood cell counts. These tests help in staging the severity of CKD, providing guidance for management and prognosis.
A newer blood test that assesses levels of symmetric dimethylarginine (SDMA) has shown promise in early CKD diagnosis. SDMA concentrations increase before serum creatinine levels rise, allowing for earlier intervention and treatment (VCA Hospitals).
By being aware of the challenges in early CKD diagnosis and understanding the potential complications associated with the disease, cat owners can work closely with their veterinarians to provide the best possible care for their feline companions. Regular check-ups and monitoring are crucial for managing CKD and improving the quality of life for cats with this condition.
