If your cat suffers from lower urinary tract disease you can help by feeding it a diet dry food which provides optimal nutritional support for its urinary system. Urinary tract disease can lead to urinary stones (including struvite and calcium oxalate).
support your cat's health with Royal Canin urinary s/o
Royal Canin Urinary S/O products were developed as an adjunctive treatment for cystitis and urinary stones.
a science-based urinary s/o formula for your cat
Indications:
  • Dissolution of struvite uroliths
  • Prophylactic treatment/prevention of calcium oxalate stones
  • Prophylactic treatment/ prevention of struvite stones
Contraindications:
  • Pregnancy, lactation, kittens
  • Chronic renal failure, metabolic acidosis
  • Heart failure
  • Hypertension
  • Parallel use of urine acidifying medication
Key benefits:
  • Struvite dissolution: URINARY S/O helps to dissolve all types of struvite stones.
  • Urine dilution: Diluting the urine makes it less liable to form struvite and calcium oxalate stones.
  • Low RSS: Helps to lower the concentration of ions contributing to crystal formation.
  • Protecting bladder mucosa: Glycosaminoglycan (GAG) is a natural part of the bladder mucosa and protects against bacteria and toxins.

Changing your pet's diet and length of treatment:
Your pet will need to stay on this diet for 5 to 12 weeks, or until the stones are dissolved. It is advisable to feed this diet for a further 6 months to prevent a recurrence.

Further information:

Therapeutic veterinary diets are carefully formulated and recommended to be used in conjunction with veterinary advice and support. Royal Canin strongly recommend you seek advice from your Vet prior to and during feeding of any of these products to your pet.

Good but getting pricey
I have both of my male cats on this RC dry food, which they love. It helps or even prevents urine infections that male cats are prone to. The only problem is that the price increases every few months. Not very long ago this bag was £11.99

Prevention !
My elderly boy, has been on Urinary S/O biscuits for some while. They have definitely helped in the prevention of crystals forming again in his urethra, which for him was life threatening.

Product change?
My cat has been on this for over eight years with no issues at all but since getting a new bag won’t eat it. When he does try a few he gags on them ! Will be switching him to a different brand

Has Not Stopped UTI Flare Ups
My female cat has suffers episodes of what im told is a UTI, where the urine turns dark yellow / brown with some blood present. A blood test was taken to rule out kidney disease. They gave her an anti inflammatory injection & an antibiotic. They also recommended a special urinary diet which helps make the PH of urine less alkaline & eliminates crystals. This all helped but after feeding this expensive urinary S/O dry feed for almost a year a flare up has now occured with haematuria present.

Highly Recommend for Urinary Issues
My cat suffered from blocked bladder problems and a build up of crystals. He spent over 5 days in the vets and overnight in pet hospital when he suffered from his blocked bladder. He had several catheters to help unblock him and flush out the crystal build up. Ever since putting him on this special diet he has has no further problems and has improved so much. This food also encourages him to drink so much more, which helps with his urinary problems.

Worked for my cat
After an emergency blocked bladder situation that involved a hospital stay, a lot of stress and $$$ I switched to this food. 3 years later, he's not had any bladder issues and don't even think about it anymore. I make sure he gets wet food as well.

Great for struvite crystal problems
My two maine coons have been on this diet for 4 years after my female developed struvite crystal problems and had to have surgery. The vet advised to go onto this diet. Although very pricey we havent we stuck to it and never had issues again since. Cats are now over 10 years old.

Fantastic product
After several episodes of cystitis that were cleared with medication then an expensive operation to remove a stone my cat has never had another bout of cystitis since I put him on this four years ago. I add a little water into his bowl with his food every morning and night then he has to drink that before he can get to the food. He seems happy enough with it and the re-ordering, service and delivery is so easy

this food keeps my Henry alive and healthy
Henry could not pee. 2 days as an inpatient at vets. they said he needed a low protein diet.. This is perfect for him.Even my other cat Tonks quite likes it although she is really a wet food cat.

Simply the best food for the condition- end of discussion!
I have had 2 boys now with struvite crystal problems. My old lad (now deceased) had no problems at all once he was put on this food by the vet, and happily ate it till the day he passed. When my new lad started having the same problem, it was back to this food straight away- then my vet changed her brand... One seriously unhappy boy who starved himself for 10 days rather than eat the new brand. Straight back to Royal Canin for us, and now all I have left in his dish are tiny crumbs... sorted!

Used this for 10 years +
Bessie was very poorly, vet suggested Royal Canin and her trouble cleared up, I have kept her on this dry food she has a dish of it down all the time and grazes throughout the day and night. I don’t give her any cat food at all as it’s makes her ill again so she has fresh chicken, cod roes, pilchards, frozen cod portions etc and is 100% clear on this diet.
