Cat Diseases - Kidney Disease/Renal Failure

Cat kidney
  • Kidney failure is the inability of the kidneys to remove waste products from the blood.
  • The buildup of toxic wastes produces the signs and symptoms of uremic poisoning.
  • Kidney failure can come on acutely or occur gradually over weeks or months (Chronic renal failure).
  • Chronic renal failure is a leading cause of death in pet cats. It takes place so slowly, that by the time the symptoms have become obvious, it may be too late to treat the condition effectively.
  • The following are some causes of both chronic and acute kidney problems:
    • High blood pressure
    • Infection
    • Immunological disease
    • Congenital or hereditary disease
    • Cancer
    • Decreased blood flow to kidneys
    • Kidney trauma
    • Urinary obstructions such as kidney stones
    • Exposure to toxins, especially antifreeze

  • Do not give your cat any over-the-counter medications without instruction by your veterinarian.
  • Make sure she has access to fresh water at all times.
  • It may be difficult to determine a specific cause of kidney disease. Emergency treatment and hospitalized care may be needed depending on the stage of kidney failure a cat is in.
  • Although there is no cure for chronic renal failure, there are numerous steps that can be taken to minimize the symptoms and slow the progression of the disease.
  • The following are possible treatments:
    • Treatment of underlying cause of kidney failure (e.g. antifreeze toxicity, infection)
    • Drugs to enhance urine production
    • Therapeutic diet
    • Management of electrolyte abnormalities
