Iams® Veterinary Formula™ Renal Plus

Recommended For: Print


Renal Plus is designed to address the nutritional needs of your cat once kidney problems have been identified by your veterinarian. It provides optimum protein levels to help maintain body condition, muscular mass, and immune and organ function. There are special ingredients to minimize wastes building up in the bloodstream. It has reduced phosphorus levels to help slow progression of renal disease. Your veterinarian can explain how the formulas may help and which one is right for your cat.

How can the Renal Management System help?
Nutrition plays a critical role in managing the signs and progression of kidney problems. Iams® Veterinary Formula™ Renal Plus nutritionally manages progression with:

  • Patented Nitrogen Trap Fiber System, which diverts the waste products of protein metabolism from the bloodstream into the colon, thereby reducing the workload on the failing kidneys. This allows for optimal protein intake to maintain muscle mass, immune system and glomerular filtration (filtering of fluids through the kidneys).
  • Targeted omega-6:omega-3 fatty acid ratio helps increase glomerular filtration rate
  • Added potassium citrate to help control metabolic acidosis (a condition in which the pH of the blood is too acidic), which occurs when the kidneys lose ability to filter waste products from the bloodstream.
