Royal Canin's Renal Special (RSF 26) is a complete food for cats that suffer with chronic renal insufficiency. It has been formulated to maintain and support healthy renal function and reduce the formulation of oxalate stones.
The Renal Special recipe provides a new texture, taste and aroma to the original dry Renal diet, to help keep your cat from losing interest in their food.
The very low phosphorus content prevents retention which can lead to secondary hyperparathyroidism and renal failure. The food contains a synergistic antioxidant complex which will help boost your cat's natural defences, maintain healthy cells and DNA, and neutralise free radicals.
Omega 3 long chain fatty acids help support a lower glomerular pressure which will help to prevent GFR. Additionally, an increase in uraemia often causes the development of gastric or intestinal mucosal ulcers. This will be prevented with added FOS and zeolite.
RENAL SPECIAL is a complete dietetic feed for cats formulated:

I bought a small pack of the '26' as Molly was eating the '23' with vigour, but she loves them. Small enough pieces for her too. The profile said tasty hence buying them as renal food is known to be bland.

This is the very favourite food of my little Burmese cat. She has only one kidney and that is not working so well but thisRoyal Canin Special food she loves and has even put on weight, which is the aim.I am so pleased with it and relieved to have discovered it after a couple of years trying everything I could .

Below are some recent questions we've received regarding Royal Canin Feline Veterinary Diets Renal Special RSF 26 Cat Food, including answers from our team.
Helen
What is the difference between the RF, RS and RSF brands of cat food?
Hello,
Thank you for getting in touch.
I have had a response from Royal Canin regarding your question.
They said:
We have three Renal dry diets available; Renal (RF23), Renal Special (RSF26) and Renal Select (RSE24). We know that cats with renal disease often go off their food so we have developed a range of foods with different flavours, textures and aromas that all provide the same level of support for your cat.
Renal Special and Renal Select contain pork as the protein source, whereas we use vegetable protein as the main protein source in the Renal diet. Pork has a low mineral content which helps to enhance the palatability and also increase the digestibility. Both the Renal Special and Renal Select have a slightly higher protein content than the Renal diet, but this is still fine for cats with renal disease, as we use a highly digestible protein. The higher protein also helps to enhance the palatability of the food. The Renal Select has a double texture, pillow kibble which is designed to make the kibble more palatable.
All three of the diets are formulated to support renal function in cases of chronic kidney disease and have an adapted content of high quality protein which helps reduce the kidney's workload. They contain EPA and DHA, a complex of antioxidants and a low phosphorus level.
Hope this helps,
VioVet.

Do I need to put phosphate binder on royal canning renal special? Also is it OK to syringe feed the kibbles after soaking.Thank you
Hi Janice, it would be perfectly okay to soak the kibbles and syringe feed if your cat is having difficulty eating. There is also a wet variety available here which, if your cat is able to eat wet foods, might be an easier option for you.
The diets have been developed to be low in phosphorous, but providing additional support with Ipakitine would not not be a bad idea, as it also has the ability to bind uraemic toxins and block their absorption. It would work with the diet to greatly reduce the strain on the kidneys, and help to prevent phosphorous and toxin build-up.
