Kidney disorders are a relatively common problem in cats, particularly for ageing cats. Diet plays an important role in helping to support kidney function, so it’s vital to choose a diet for your cat that is specially formulated to support their condition.

ROYAL CANIN® Renal is a dry kibble diet tailored to help support adult cats with Chronic Renal Insufficiency. When your cat’s kidneys are not working efficiently, it often means that phosphorus cannot effectively be filtered from the blood stream.

ROYAL CANIN® Renal is specially formulated with a low phosphorus content and provides a moderate amount of high-quality proteins to help support kidney function. ROYAL CANIN® Renal contains an adapted energy content to reduce meal volume, which helps to support your cat’s reduced appetite. To further support food aversion and/or a reduced appetite, ROYAL CANIN® Renal is formulated with a specific aromatic profile that helps to stimulate your cat’s appetite. The shape, size, and texture of the kibble is also specifically tailored to appeal to cats.

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 with three different formulations: fish, beef and chicken. The variety of formulations and aroma profiles help to stimulate and support your cats 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 help support kidney function in 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.

Royal Canin Renal Adult Dry Cat Food is suitable for Azotaemic Chronic Kidney Disease (IRIS stage 2* to stage 4), Chronic Kidney Disease with proteinuria (IRIS stage 1 to 4), Management of calcium oxalate urolith recurrence in cats with impaired renal function, Prevention of recurrence of urolithiasis requiring urine alkalinisation: urate and cystine uroliths.

This is the first time I have purchased these biscuits and 3 of my cats who have various stages of kidney disease enjoyed then. However their favourite biscuits are Renal Select so I will not be buying Renal regularly.

Difference between RF23 & RSF 26?

Susie Poulton

  • VioVet customer since 2009
  • From: Oxfordshire, United Kingdom

What is the difference between the 2 Renal Dry foods from Royal Canin (RF23 and RSF 26)? The RSF 26 says it is more palatable so is it just for fussier cats, or is it slightly better quality? Or are they for different types of kidney disease? Would there be a medical reason as to why you should feed one and not the other in particular circumstances?
Thanks for your help.

  • VioVet Staff

The RF 23 is more severely restricted in phosphorus and protein and is more useful for more advanced cases of chronic renal insufficiency. As such it is also less palatable, so the RF 26 is more likely to be accepted by the average cat. They are both used for the same types of problem. If reduced renal function has clearly been demonstrated on blood and urine tests, then the best diet is probably the RF 23. However a lot of these cats are not keen to eat anyway, so giving them a diet which is not particularly palatable is counter productive. It is more important that they eat enough of something rather than not enough of a slightly better food. Having some of both to hand might be best, but aiming to use the RF 23 for preference.
