Product details

Royal Canin Veterinary Diet Feline Renal RF 23 is a complete dietetic feed for adult cats struggling with renal failure, specially formulated to appeal to even the most unenthusiastic eater.

How it works 

Royal Canin Veterinary Diet Feline Renal RF 23 uses varied sources of animal proteins and a wide choice of aromatic profiles designed to be especially appetising to your cat. A number of flavours and textures help make the medicine suitable for cats with a range of conditions. If your cat has problems chewing, for example, they might prefer a recipe with a softer texture. This wide range of nutrients also helps to support a balanced digestive system as the appealing formulae encourage your pet to eat a range of recipes despite their reduced appetite.

Renal failure is often accompanied by phosphorous retention, which can lead to the glandular disease secondary hyperparathyroidism. The low levels of phosphorous in this recipe help to support normal renal function.

You may also find that renal failure limits the ability of your cat's kidney to filter blood. The food is also supplemented with omega-3 long chain fatty acids which can combat this decline and restore some of the kidney's function.

It's also fortified with Royal Canin's patented complex of anti-oxidants, which can aid in neutralising free radicals, helping support the overall health of the immune system and maintain DNA cells.

Key benefits

  • increased palatability to keep your cat eating
  • maintains your cat’s nutrition through varied protein profile
  • reduces phosphorous intake 
  • helps restore kidney's ability to filter blood.

When to use it

Kidney failure often causes cats to lose their appetite and can be accompanied by severe symptoms including vomiting, lethargy, and diarrhoea. In some cases, your cat could become severely anorexic. Royal Canin Veterinary Diet Feline Renal RF 23 is a complete diet and can often be used immediately after diagnosis to improve your cat’s appetite and restore their nutrition.

Because veterinary diets are formulated for the nutritional support of pets with specific clinical conditions, we recommend that you only use them under professional advice. For more information on feeding Royal Canin Veterinary Diet Feline Renal RF 23 to your cat, please consult your veterinary surgeon.

  • Great alternative
    My cat has a kidney disorder and was prescribed Hills prescription kidney food . He has had this for a number of years and slowly stopped eating it. I tried the Canin alternative and he loves it and it’s cheaper so win win!

  • Excellent food
    Purchased this food as I found out my cat has kidney failure she has been using it for three months and her blood test results have shown all her readings are in the normal range now would highly recommend to anyone else who has a cat with this problem I did catch it early so she wasn’t at the severe stage but it does prove it works, My cat is nearly 12 years and hopefully she can live a longer happy life.
