Acute Kidney Injury (Acute Kidney Failure) in Cats The Importance of Early Detection and Treatment of Acute Kidney Failure in Cats

Acute Kidney Injury (Acute Kidney Failure) in Cats

If left untreated, acute renal injury, a hazardous illness that can affect cats, can result in death or irreversible kidney damage. We discuss this condition more in this article.

What is Renal Failure In Cats?

Acute Kidney Injury (AKI), also known as Acute Kidney Failure, is a serious condition that can occur in cats and can lead to permanent damage to the kidneys or even death if left untreated. The kidneys, which are in charge of filtering waste from the blood and preserving fluid and electrolyte balance in the body, are characterized by this disorder by an abrupt reduction in function.

The causes, signs, diagnosis, and available treatments for acute kidney injury in cats will all be covered in this article.


Acute Renal Failure in Cats Has Several Common Causes, Including:

  • Dehydration: Lack of fluid intake can lead to decreased blood flow to the kidneys and cause AKI.

  • Toxicity: Exposure to toxic substances, such as certain medications, antifreeze, and chemicals, can damage the kidneys and lead to AKI.

  • Infection: Bacterial, viral, or fungal infections can damage the kidneys and cause AKI.

  • Blockage of the urinary tract: Obstruction of the urinary tract, such as stones or tumors, can prevent waste products from being removed from the body, leading to AKI.

  • Shock or injury: AKI can result from severe injury or shock that reduces blood supply to the kidneys.

  • Chronic Kidney Disease: AKI may result from Chronic Kidney Disease in its advanced stages.


The symptoms of Acute renal failure in cats can vary and may include:

  • Increased thirst and urination

  • Reduced appetite

  • Vomiting

  • Lethargy

  • Bad breath

  • Weakness

  • Changes in urine output

Kidney Failure in Cats Prognosis

  • It often takes a combination of physical examination, laboratory testing, and imaging to diagnose renal kidney failure in cats. Among the diagnostic procedures that might be used are:

  • Blood tests: Blood tests can assess the amounts of waste products in the blood, including creatinine and urea nitrogen, which can reveal renal function.

  • Urine Tests: Urine tests can evaluate the concentration of waste products in the urine and can help determine if the kidneys are functioning properly.

  • Ultrasound: Ultrasound can help visualize the structure and size of the kidneys and detect any abnormalities.

  • Biopsy: The root cause of AKI can be determined with a kidney tissue biopsy.

Your veterinarian may also take a detailed medical history and ask questions about your cat's behavior and symptoms to help determine the cause of AKI. Once a diagnosis is made, your veterinarian will work with you to develop an appropriate treatment plan to support your cat's recovery.

How to Reverse Kidney Failure in Cats

Reversing kidney failure in cats can be challenging and may not be possible in all cases. The extent of reversibility will depend on the root cause and the seriousness of the problem. The main objectives of therapy are to maintain renal function and stop additional harm. A few possible treatments are as follows:

  • Fluid Therapy: The administration of fluids, either under the skin or intravenously, can help rehydrate your cat and flush out waste products from the blood.

  • Medications: Antibiotics such as CLAVAMOX or DOXYCYCLINE may be prescribed to treat infections. Also, medications to control vomiting or nausea may be necessary.

  • Dietary Changes: A special renal diet may be recommended to help support your cat's kidneys and reduce the workload on the kidneys.

  • Dialysis: To eliminate waste from the blood in extreme situations, dialysis may be required.

  • Surgery: Surgery may be required in situations of urinary tract obstruction to eliminate the obstruction.

Depending on the extent, longevity, and underlying cause of the ailment, a cat with AKI may or may not recover. With prompt and appropriate treatment, many cats can recover from AKI and return to a normal, healthy life.

Preventive Measures

To help prevent Acute kidney failure in cats, it is important to:

  • Ensure Adequate Hydration: Provide fresh water and encourage your cat to drink. Offer wet food to help increase fluid intake.

  • Monitor Medications: Avoid giving your cat medications without first consulting your veterinarian to avoid sudden kidney failure Some medications can be toxic to the kidneys.

  • Avoid Toxins: Keep your cat away from toxic substances, such as antifreeze, household chemicals, and prescription medications not intended for use in cats.

  • Maintain a Healthy Diet: Feed a balanced, nutrient-rich diet to help maintain health and support kidney function.

  • Regular Check-ups: Regular check-ups with your veterinarian can help detect any underlying health issues and monitor kidney function.

  • Manage Chronic Kidney Disease: If your cat has Chronic Kidney Disease, following your veterinarian's recommendations and closely monitoring kidney function can help prevent AKI.

By taking these precautions, you can lower your cat's risk of developing an acute kidney injury and ensure its long-term health and well-being.
