ROYAL CANIN® Renal Special is a dry kibble diet that is formulated to nutritionally support adult cats with Chronic Renal Insufficiency. Kidney disorders can be common in cats, particularly older cats. Your cat’s diet can play an important role in supporting this condition and providing nutrition that helps to maintain their overall health and wellbeing. The kibble in ROYAL CANIN® Renal Special has its own distinct shape, size, and texture, as well as a unique aroma.

Thanks to its specific aromatic profile and dedicated kibble shape, ROYAL CANIN® Renal Special helps to stimulate your cat’s appetite in cases of food aversion. ROYAL CANIN® Renal Special is specially formulated with a moderate, high-quality protein content and a low phosphorus content to help support renal function. To help support your cat in cases of a reduced appetite, ROYAL CANIN® Renal Special contains an adapted energy content to reduce the volume of their meals.

Attracting your cat to their food bowl can be difficult in cases of food aversion. To cater to each cat’s individual preferences, ROYAL CANIN® Renal is also available as wet food in three different formulations: fish, beef, and chicken. With a variety of formulations, aromas and textures, it’s easier for you to help stimulate and support your cat’s varying appetite. If your cat enjoys a mixed diet of wet and dry food, be sure to reference the on-pack feeding guides to ensure a healthy daily food intake for your cat.

ROYAL CANIN® Renal Veterinary diets for cats are formulated to support cats with Chronic Renal Insufficiency. Each formula in the ROYAL CANIN® Renal Support range contains specific nutrients to provide your cat with a complete and balanced diet.

Verified Purchase

i am sure Royal Canin Renal biscuits have kept both Chunky and Shadow alive, they are the only biscuit they have - Chunky has kidney problems and Shadow is old, both in late to mid-teens.

55 Finally a CKD food my cat will eat!
Verified Purchase

By on 11 July 2020

My cat has had CKD for several years now and flatly refuses to eat any of the special diet wet food (how we have the technology to have astronauts living in space yet cannot create a palatable food for cats with CKD is beyond me). However she seems to have taken to this with great enthusiasm, which is about as much of a recommendation as I can possibly give!

Different names?


What is the difference between the RF, RS and RSF brands of cat food?

  • VioVet Staff


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,

Royal canning and ipikatine

Janice Lancaster

  • VioVet customer since 2015
  • From: West Yorkshire, United Kingdom

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

  • VioVet Staff

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.
