Product details

Royal Canin Veterinary Feline Renal Special RSF26 is a complete food that has been specially formulated to support cats suffering from kidney disease.

How it works

If your cat has been diagnosed with kidney disease, they will have very specific needs with regard to their diet. This complete food provides all the nutrients they need to stay healthy, as well as providing extra support for their kidneys. 

Keeping phosphorus levels low is key when dealing with kidney disease, so this food contains only a minimal amount to lessen the strain on your cat's kidneys. Top quality protein reduces the kidneys' workload, and the right combination of nutrients in the food helps your cat's kidneys to filter waste effectively. Also, low levels of calcium and Vitamin D reduce the chances of your cat developing painful kidney stones.

You might have found that your cat has lost his or her appetite since developing kidney disease. Royal Canin Veterinary Feline Renal Special RSF26 been developed to smell and taste delicious, appealing to pets with small appetites and fussy eating habits.

Key benefits

  • a complete food that gives your pet all the nutrients they need, while supporting their kidneys
  • low phosphorus levels and top quality protein reduce the kidneys' workload
  • combination of nutrients to improve kidney function
  • low levels of calcium and vitamin D reduce the formation of kidney stones
  • appealing smell and taste to tempt cats who have lost their appetite.

When to use it

The function of healthy kidneys is to filter your cat's blood and remove waste, keeping the right level of vitamins and minerals in your pet's body. If the kidneys become damaged, waste and toxins might not be safely removed, and can make your pet seriously ill. It's therefore vitally important to take your cat to the vet if you notice any potential signs of kidney damage.

Symptoms to be aware of include drinking or urinating more than usual, weight loss, a decreased appetite, and vomiting and diarrhoea. Although kidney disease is more common in older cats, it can also occur in younger pets, particularly if they've swallowed a poison such as antifreeze. If your vet does diagnose kidney disease, there are a range of treatment options they might offer for your cat, such as medication, intravenous fluids, or a specialist diet. 

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 Feline Renal Special to your cat, please consult your veterinary surgeon.

  • This food has saved our precious cat’s life
    Royal Canin RSF26 has literally saved Preeti’s life after being given a very short time to live. Nearly 2 years on she is fitter and more content than ever. She loves her food and never tires of it. Thank goodness for this wonderful product. Louise

  • Cat loves it!
    Our cat has had these biscuits for 2 years now as her kidneys are starting to slowly deteriorate. She had never got bored of them. The bonus from ordering them from this site is they are a lot cheaper than the vet!!
