Kidneys are important because they remove waste substances from the blood, and maintain the normal balance of fluid and minerals within the body. Once kidney damage occurs, the consequences are usually irreversible.

Hill's nutritionists and veterinarians developed Prescription Diet® k/d®, clinical nutrition especially formulated to support your cat's kidney health. In fact, k/d is clinically tested nutrition to improve & lengthen quality of life.

Lifelong Care I have been a Veterinary Technician for over ten years, and a pet owner all my life. My two cats that I have had since birth have been fed Hill's Science Diet Kitten, Maintenance, Light, and Hairball throughout their lives. They are 14 1/2 and 16 1/2 years old now. Three years ago they both entered into early renal disease. Having fed Hill's all their lives I immediately started the k/d diet. My vet (and boss) gave me a sample of another prescription kidney diet and they didn't like it. Smart kitties. They ate the dry k/d for over two years and to help them out I started adding the canned k/d twice a day as well. They are thriving with shiny coats and healthy appetites. Thanks to Hill's diets they are living long, happy lives with a very happy owner! January 6, 2014
My Cat Responded So Positively.... For years my cat was on CD's because of a urinary tract infection that almost killed him. He never had that problem again but at 15 yrs old recently began to drink water excessively, his fur became dull and shaggy looking and he didn't have a playful spirit like he used to. At his annual exam his vet determined he now has kidney concerns so changed the diet from CD's to KD's and in 2 weeks time my cat is like a brand new kitty! He's playful again and his coat is more shiny. He still drinks lots of water, but that's good for him since he'll soon be 16 years old on his birthday! Thank you so much for having a prescription food that truly has prolonged my cat's life on more than one occasion!!!!! Sherri, Dallas/Ft Worth TX August 1, 2014
The only choice My10 year old kitty was diagnosed with kidney decline 4 years ago. My vet recommended the feline K/d to help it not get worse. Well…it actually got better. We were both very excited. Her levels have stayed at the improved numbers since and have only now begun to decline again very, very slightly. She's no spring chicken, but knowing that her food can have such and amazing affect on her health blew my mind and I could not be more thrilled. It's pretty expensive but how can it not be worth it?

KD prescciption is great I thought my Solomon 15 yrs old was going to die. His kidneys where almost completely shut down. Vet gave him fluids, antibiotics and told me to feed him KD prescription. He loves the dry and he his like 10 yrs old now. Very happy and I think he will be around for a long time. The coupons really help also. May 1, 2014
K/D is extending MomaCat's life. When you have an 18 year old cat who is a part of the family and has early kidney failure, it is great there is a product like k/d to help keep her going. We use the dry formula in their bowl and the can product twice a day to help give her medicine that we mix in with it. After a full year, her numbers remain the same and she isn't getting any worse. Our previous cat made it to 22 and Moma Cat wants to break that record ! October 19, 2013
Helped my cat live a long time! I have been feeding my cats K/d for numerous years ever since my boy cat was starting kidney problems. It helped greatly and my boy cat lived to be 20 years 6 months old and he went to the Rainbow Bridge November 12th. My female cat went to the Rainbow Bridge in January of this year at 22 years old. I feel that feeding them k/d really helped and my vet said that my 16 year old should keep on it. It is great that you have food geared to a certain problems for both cats and dogs. I highly recommend it if your vet tells you to buy it. Yes, it's expensive and wish more coupons were available in the coupon sections for the prescription food, but it is definitely worth the price to keep your fur babies with you for as long as they can live.

This product seems to keep my cat's condition from getting worse. I have been using this product for over a year. It was recommended by our vet. Initially I tried the canned wet food. Since my cat (Bob) was use to only eating dry food after two cans of wet food (same product) switched to only the dry food. Since my cat (Bob) does not like stale food I buy the 8 lb bag and divide into 3 plastic bags. This works out real well and Bob eats a normal serving every day. Only when I open a fresh bag of quality non-prescription dry cat food for my second cat (Betty) I need to keep an eye on Bob so he does not eat Betty's food. After Betty's bag of cat food has been open for two weeks, Bob no longer tries to eat her food. Instead, he acts like he is trying to cover it like his messes in the litter box. Since Bob's been eating this for over a year he still acts like before he was diagnosed and needed a special diet. October 10, 2014
My 17 yo cat enjoys k/d dry! When I was told that my 17 year old furry little Angel needed to be on a special diet because he was in early renal failure, I was devastated. He's a very sweet boy and we live him so much. Also,I had already gone through, it seemed liked, every brand and flavor of soft food because of his bad teeth and was able to find one flavor of one brand that he tolerated. So,I was very concerned that finding a prescription kidney food would be just as hard. My very said most cats prefer the soft Science Diet k/d, do I left with 3 cans and my fingers crossed. He ate it ok for about a week, then decided it wasn't for him. So I picked up a bag of the dry k/d, immediately, he dug right in. I was cautiously optimistic, after the experience with soft food. But one year later, he still loves it! I have little bowls of food in most of the house so he can eat without much effort, poor little guy. Thank you! February 25, 2014
