Chronic Kidney Disease In Cats

Kidney failure in cats is also termed “Chronic Kidney Disease” in cats. This disease does not suddenly affect the kidneys; instead, it is a continuous process that reaches its peak over a significant period.

Chronic kidney disease is mainly found in elder cats that gradually increases, and the disease worsens over time. In this article, we will discuss chronic kidney disease in cats.

If the kidneys work in good condition, they usually help the body balance the fluids. Kidneys also produce some hormones and also regulate electrolytes in the body. The waste products are excreted via urine.

However, for cats suffering from chronic kidney diseases, the normal functions of kidneys are challenged and interfered with by several factors. This interference can result in the decline of kidneys by showing various signs of damage in the cat’s body.

Unfortunately, chronic kidney disease is not a curable or reversible health disorder in cats. Only we can prevent this disease by following specific measures and providing quality support and treatment to our cats.


Causes of Chronic Kidney Disease

Mostly, the causes are unknown, while some of the notable reasons for kidney disease in cats include:

Polycystic Kidney Disease

The inherited polycystic kidney disease (PKD), most common in Persian and related cats, causes multiple fluid-filled cysts to gradually replace healthy kidney tissue.


The kidneys can be affected by tumors, such as lymphoma, a solid white blood cell tumor.

Infections: Pyelonephritis, a bacterial infection of the kidneys, may cause enough harm to result in chronic kidney disease (CKD).


Various toxins and drugs can harm the kidneys.


Glomerulonephritis, an inflammation of the glomeruli (individual units in the kidneys that filter blood), can cause chronic kidney disease (CKD) if it persists for an extended period.

Other reasons for cats’ chronic kidney diseases such as birth defects. In addition, the condition’s progression might be slowed if an underlying cause can be found, which in some cases might be treatable. However, most of the time, treatment focuses on controlling the disease and its side effects.

Symptoms of Chronic Kidney Disease

There are many signs of this fatal disease. Some are clear, while some are pretty vague. Some result from piling toxins in the body, while sometimes signs show up due to the body resisting the disease.

  • Loss of weight
  • Lack of appetite
  • Fatigue
  • Heightened thirst
  • More frequent urination
  • Poor coat
  • Hypertension (high blood pressure)
  • Vomiting
  • Bad-smelling breath (halitosis)
  • Weakness
  • Anemia

Management of Chronic Kidney Disease

Although we cannot provide adequate treatment for the disease, we can manage and control it by adopting specific measures.

  • Increasing the Water Intake
  • Minimize the Protein Content
  • Decrease in Phosphate in Cat’s diet
  • Control Blood Pressure and Anemia in Cats
  • Kidney Transplants


Older cats are most often affected by chronic renal failure (CRF) or chronic kidney disease (CKD). Cats younger than three years old account for only 10% of the cases.

Typical aging changes frequently excuse early disease symptoms like weight loss and poor coat quality. The kidneys deal with their inability to effectively remove waste products in the early stages of kidney failure by excreting them at a lower concentration over a larger volume.

Indeed, we cannot provide sufficient treatment for the disease, but we can adopt specific measures to manage the disease properly so that cat can live happy years of her life.
