Iams® Veterinary Formula™ Renal Plus

Recommended For: Print


Multi-Stage Renal 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. 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 Formulas Renal – Multi-Stage Renal™/Feline nutritionally manage 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).
  • omega-6:omega-3 fatty acid ratio targeting 5:1, which helps reduce intrarenal blood pressure (canine), helps minimize inflammation (canine) and helps slow progression.
  • potassium citrate to counter the effects of 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.
  • reduced phosphorous content compared with that in many maintenance diets. Dietary phosphorous is essential for cell structure/function and bone development in dogs and cats. However, in animals with renal failure, phosphorous levels are often abnormally high. Phosphorus is believed to play a role in the progression of kidney problems in dogs and cats.

These guideline amounts are a starting point and your cat may need more food depending upon age, activity and temperament. In order to reach optimal body condition, you may need to adjust food intake. This chart represents the total recommended volume of food per day. You should divide the total recommended feeding amount by the number of times you feed your cat per day to get the actual portion size per feeding.
