For cats with kidney problems, Purina Pro Plan Veterinary Diets NF Kidney Function Feline Formula offers balanced nutrition to help support the kidneys. NF is formulated with low sodium, phosphorus and protein to help reduce the workload on the kidneys and help cats with kidney problems feel better. It offers dietary benefits that provide optimal nutrition while meeting your adult cat's special needs.

Key Benefits

  • Kidney disease can occur in cats of all ages, but it normally appears in that of older pets. It can't be cured, but with proper treatment and dietary management you can help make your cat much more comfortable.
  • Purina Pro Plan Veterinary Diets NF has been specifically formulated to minimize the sign of kidney failure and help slow the progression of the disease.
  • Restricted amounts of high-quality protein, low phosphorus levels, and a reduction in sodium all help reduce the workload on the kidneys. Added B-complex vitamins help to protect the body and break down nutrients.
  • Designed for cats with chronic renal failure, hepatic disease associated with encephalopathy, or any condition that benefits from restricted sodium levels.
  • Made in the USA!

  • Great shipping

    I can't really rate this too high since I'm not eating the food. She seems to like it ok, but she'll eat anything as long as it's a dry food. It was great that they contacted my vet to get approval, shipping was fast and I like the idea of the auto re-order. If she continues to eat, I'll definitely consider the auto ship. And it was convenient since no one in town carries this formula.

  • Great product and service

    Our vet recommended this food for our cat due to early stage kidney disease. He loves it and has started to regain weight. I must say that I am amazed with the excellent customer service we experienced using chewy for the first time. I highly recommend them!

  • Kitty likes those kibbles

    By on

    My very finicky 17 1/2 year old female kitty didn't sniff around too much but then just gobbled the goodies. (Never ate one single from Hill's or Royal Canine was awarded more than 2 sniffs.) Now hope that this food helps her with the renal decline. I gave it 4 * only because I'd prefer smaller bags.

  • Just what we needed!

    By on

    Our 13 year old cat was recently diagnosed with kidney disease. She used to eat anything, but turned her nose up at Royal Canin and Hills when we tried those. We tried a sample of this from the vet and she loved it! I ordered from Chewy later in the afternoon one day, and even though my vet needed to be contact to verify the prescription, it was still at my door the next day with normal delivery! I was impressed!

  • Great food!

    My cat had kidney disease this past July (he is 15) and my vet recommended this food to prevent further issues. He is eating better and has more energy after only a couple months on the NF diet! I would definitely recommend!

  • Way to go Purina

    By on

    We are so thankful for your new Kidney diet food for cats . Our 8 year old cat was diagnosed with kidney failure one year ago and he had to be put on a special diet. We were prescribed Hills Science diet food for kidney failure and he loved it. Sadly, Hills decided recently to change their formula for the kidney food and he hated it. We tried Royal Canine brand for kidney failure and he hated it. You were our last hope, because we honestly did not know what we were going to do if he didn't like your brand of dry food for kidney failure. HE LOVES IT!!! Thanks for allowing us to keep our kitty cat around a little bit longer.

    Wish I would have known about this product sooner. It has really helped our older cat that was having problems. Now our other two will be more prepared. Excellent product for urinary issues.

  • Prescription Diet for Older Kitty with renal decline.

    By on

    I have a 15 year old cat with renal decline. I do not like Science Diet products and conferred with my vet which Prescript renal diet would be best. We both agreed from what was available that Pro Plan NF Kidney Function looked the best. My cat actually likes it and has been eating it very well, unlike alot of Prescript. foods. My vet submitted the okay for it and Chewy had it here very quickly. Will continue ordering it from them.
