IAMS Veterinary Formula™ Renal Plus

IAMS Veterinary Formula Renal Plus is designed to address the nutritional needs of your cat once kidney problems have been identified by your veterinarian.

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—Multi-Stage Renal™/Feline can 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.

Rated 5 out of 5 by from Not sure why IAMS renal is not better known The can is full of a thick rich mixture that my cat immediately and aggressively ate. It is wonderful to see her enjoying this product after many failures of renal cat foods - she turned away immediately at many - and right now, she is happily cleaning up after a much enjoyed meal. I watered the mixture down a bit and she now just finished her third happy meal of chomping and licking. I am surprised that Iams doesn't market the prescription line more aggressively - I am first with the palatability and am sure it is better than not feeding her a diet for early stage CRF. I am glad that I found this!

Rated 3 out of 5 by from Cat Likes It; "Intermittent Only" Worries Me My cat with CKD likes this food, but I am troubled by the review above stating this food is "for intermittent feeding only," which means it's not a complete and balanced diet. I am alternating this with other foods for my cat, but I would need to know what this one's missing before I would recommend it to others. I might raise my rating if I got some reassurance on this issue. How often is it safe to serve it?

Rated 2 out of 5 by from my cat has gone downhill ever since he started Once my 15-yr-old male cat was diagnosed with borderline kidney disease, my vet prescribed renal support canned food only (as opposed to dry), and when I asked, ok'd this specific brand/formulation. I followed the dr's instructions to a "t", but looking back after 4 months it seems to me that his overall wellness has declined since this food was started. You won't find it on this website (WHY?), but the can says, "For intermittent feeding only". I only read the can (trusting my vet instead) because I was confused by his apparent worsening affect. I have 20/20 vision and don't require reading glasses, but I couldn't read the tiny print even with a 3x Sherlock Holmes-style magnifying glass--I had to use an 8x magnifier which is designed to examine 35mm negatives! My question: Have I inadvertently malnourished my senior cat for 4 months by exclusively feeding him this food? He's going back to the vet today because he's faring so poorly This after spending $3000 last weekend at the emergency hospital and a whole sheet of diagnostic tests showing nothing wrong (he was constipated and throwing up so I had to take him in). Does malnutrition show up in blood work? One of the things I'll ask the vet today. IMO Iams should put the warning of "Intermittent Feeding Only" in LARGE print, on the front of the label, and also provide this warning in the specs on its website, and all sellers who offer this product should display this caveat prominantly as well. I am thoroughly disgusted and heartbroken at my cat's current condition and don't know if we'll be able to bring him back from what looks like the brink of death.

Rated 5 out of 5 by from My cats prefer this food over other renal foods I have two cats on renal diets: one with chronic kidney disease and another with hepatic encephalopathy. Both cats would barely eat the other renal foods that I tried, and the weight of one cat had dropped to the point of concern. My vet provided me with a can of this food and both cats devoured it! My vet is now ordering this food for me by the case. I am actually saving money by buying this food, as I am not tossing half of it in the trash because the cats will not eat it.
