Royal Canin Veterinary Diet® Feline Renal Support S dry cat food

Cats and dogs with CKD can often have waxing and waning appetites. Since pets rely on more than just taste when determining what they will eat, ROYAL CANIN® RENAL SUPPORT diets include several aromatic profiles along with kibble texture, shape and size that can help stimulate decreased appetites. Available in multiple aromatic profiles, in both wet and dry food, the diets can be easily mixed or rotated to provide multiple feeding options.

  • 3 dry and 3 wet options for both cats and dogs providing 9 different feeding combinations
  • All RENAL products have similar nutritional profiles, easing the transition when introducing product rotations without concern for digestive upset
  • Click here to view feeding combinations based on the dry options A, S, F and wet options E,T,D

Renal Support S dry is a high energy and highly digestible diet for cats that has been formulated with low protein and low phosphorus levels and is intended for intermittent or supplemental feeding only.

Product Reviews
Royal Canin Veterinary Diet ® Feline Renal Support S dry cat food is rated 4.2 out of 5 by 45.
Rated 2 out of 5 by from The Jury Is Out On This New Food To my dismay, they discontinued their Renal LP Modified-P dry food I have been feeding my 17 year old cat for a couple of years. They now have three new renal diets out and I was told that "S" would be the closest to what I was feeding. The Mod-P had pork meal as the main ingredient, but now, as I compare the ingredients, I see corn as the main ingredient (then chicken fat, with pork meal third). My cat prefers pork over chicken, so I am not happy with these ingredients-I am feeding a cat, not a cow! They also went from a 7 lb. bag to a 6.6 lb. bag. I feel this was all done for profit and I am not feeding as good a product as I was. The jury is out on this new food.

Rated 5 out of 5 by from 20 year old cat reverses kidney disease I put my 17 year old cat on Royal Canin three years ago after being diagnosed with kidney disease. My vet said "buy the little bag because she might not eat it. " Three years later, I took her to vet to get her kidney function test run again. At 20 years old, her kidney function tests came back in the normal range. She never missed a meal when I switched her food. She is definitely senior and sleeps a lot but still has energy in the morning. She will run around chasing me and jump quite high.

Rated 1 out of 5 by from Where's our Pork?! My cats have been eating the pork for years and it is their favorite. It's hard enough to get a mixed cat household (in terms of health issues) to eat similar food when certain cats need to eat that specific kind of diet. Now they won't touch the new stuff. You took away my peace of mind over the fact that I didn't have to worry about whether or not my sick cats would eat. They'd always eat the pork. Now what are we supposed to do? Do you have any back stock you'd like to sell? My cat is sick. He needs to eat. We struck gold with your product but now they won't touch it and we had to fall back on Hills Science Diet KD-not their first choice. Please help me. Any suggestions as to what is most similar to pork? I've tried the A. Not sure what the S and F are? Thanks so much.

Rated 1 out of 5 by from Please bring back Renal LP Modified-P! I was very happy to find Royal Canin Renal LP Modified P - pork flavor dry cat food for my cat. He loved it over any other Rx dry food and been eating it for over a year and maintaining his health. Royal Canin discountinued that food about 6 months ago to our disappointment. Our supplier substituted it with Renal Support S dry food. Our cat rarely touches the new food. I'm back to finding something else that he might eat. Please bring back the old pork flavored Renal LP Modifed P..

Rated 1 out of 5 by from Please bring back the Reduced Protein LP My 15 year old cat had been on the Reduced Protein for 7 years, does not like any of the new Royal Canin Renal formulas. This is so disappointing as it is not easy to get a kidney cat to switch foods ( and he does not like any of the other RC renal varieties). Our vet is also frustrated as apparently RC is famous for changing formulas a lot. I wish there would be more consideration toward the cats that thrived on this formula.

Rated 1 out of 5 by from Where is the renal lp modified -p My cat has been eating this regularly for 8 years, and is definitely not happy with the new product. It also not to be as good for the cat as the old LP. I will talk to my Vet, but I'm not happy the cat sure ain't happy, so it looks like I will be switching brands! I'm hoping you meant well, but I sure looks like this was a decision made based only on profits!!

Rated 3 out of 5 by from Less pork-More corn-Smaller bag-More expensive My 20 year old cat was on Royal Canin LP for many years and did great. The new S formula has more corn and less pork and he does not like it as well as the LP. On my third bag and when I opened it, there were triangle pieces of food mixed in with the square pieces--the S formula should be all square pieces per phone call to Royal Canin. Returned the bag to the vet and got a replacement. Expiration date on bag: Jun 2016 Check your food!! He is also on the canned E and likes that.

Rated 5 out of 5 by from My cats love Royal Canin The Royal Canin Veterinary Diet for Renal Support is all I feed my two beautiful cats. My Redman is prone to urinary tract infections and after using the Royal Canin Veterinary Diet his renal functions are normal and my Bailey Boy has no problems. I feed them both the same dry food and they continue to be healthy and happy cats. I know from my research and speaking with my veterinarian that they will continue to follow the same procedures to ensure a long and healthy life.
