ROYAL CANIN Renal Special is a dry kibble diet that is formulated to nutritionally support adult cats with Chronic Renal Insufficiency. The kibble in ROYAL CANIN® Renal Special has its own distinct shape, size, and texture, as well as a unique aroma to help stimulate your cat’s appetite in cases of food aversion. ROYAL CANIN® Renal Special contains an adapted energy content to help reduce the volume of your cat’s meal. 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 cats’ varying appetite. If you feed your cat a mixed diet of wet and dry food, make sure you follow the on-pack feeding guides to ensure a healthy daily food intake for your cat.


  • Formulated with low phosphorus and moderate protein of high quality to support renal function.
  • Adapted energy content to reduce meal volume and help support a reduced appetite.
  • A specific aromatic profile with a dedicated kibble shape to help stimulate the cat’s appetite, particularly in cases of food aversion.

Good for CKD diet cats

Dry Renal cat food Anon on 13 January 2018

We gave this cat food to our poorly cat and we think it gave her at least 6 more months of life when she wasn’t eating anything else. A very good product for cats with Renal failure.

A great saving H on 29 June 2010

Royal Canin renal food was recommended by the vet for our 16 year old cat. Having checked on Pet Planet, this food was considerably cheaper than buying it directly from the vet. Our cat loves both the dried food and the pouches.
