Feline Kidney Disease Supplements

Kidneys rid the body of waste produced during metabolism. Removal of waste takes place within the kidneys through a system of nephrons. Contained in each nephron is a glomerulus, a sieve-like filtering structure. As a cat ages, the kidney's lose the ability to filter the blood due to the destruction of the glomeruli. When 80 percent of these filters are clogged or destroyed, waste levels start to increase in the bloodstream. Adding supplements or adjusting the diet may improve quality of life or slow further damage.

  1. Fluids

    • Cats can't drink enough water to properly flush the kidneys.

      Cats with severe kidney disease or renal failure are unable to drink enough water. Subcutaneous (under the skin) fluids should be administered. Administering subcutaneous fluids help the kidney flush toxins out of the bloodstream. Fluids may help cats with high potassium levels as well. A veterinarian can give these fluids or provide at home instructions.

    Protein

    • High quality protein helps maintain normal body maintenance. It also contains more essential amino acids which the body is unable to produce. Raw poultry or beef are excellent sources of high quality protein and can be fed whole or sliced. For many cats, it is better than a low protein diet. A diet deficient in protein can lead to malnutrition. If a low protein diet is required based on the needs of the cat, canned formulas are a better option over dry food. Feed a high quality protein diet until the BUN (Blood Urea Nitrogen) level is double the normal level. A veterinarian can determine BUN level through testing.

    Phosphorus Binders

    • Many cats with kidney disease have high levels of phosphorus, referred to as hyperparathyroidism. Phosphorus levels rise because kidneys are no longer able to effectively excrete it. Phosphorus binders can be added to keep phosphorus levels low. Phosphorus binders unite with the phosphorus in food in the intestine and prevent it from being absorbed.

    Omega 3 Fatty Acids

    • Omega 3 fatty acids derived from cold water marine fish can retard the advancement of kidney disease. Omega 3 fatty acids reduce inflammation in the kidneys. Vitamin E can be added because they act synergistically. Omega 3 fatty acids can be fed up to twice the recommended dose. However reduce dosage if stools become loose.

    Vitamins

    • Supplement lost vitamins and minerals.

      Feed B-complex and vitamin C to restore lost vitamins. Cats suffering from kidney disease are unable to properly recycle and retain these nutrients. B vitamins or other vitamin-mineral complexes stimulate the appetite and appear to boost the cat's feeling of well being.
