Product details

Royal Canin Veterinary Diet Feline Urinary S/O LP 34 is a complete dietetic feed for cats. Its urine acidifying properties and its low level of magnesium make it suitable for dissolving struvite stones and reducing their recurrence. It is also formulated for the nutritional management of cats with lower urinary tract disease.

Key Benefits:

  • Struvite dissolution - Helps dissolve all types of struvite stones.
  • Low RSS - Helps lower the concentration of ions contributing to crystal formation.
  • Urine dilution - Urine dilution makes the urine less liable to form struvite and calcium oxalate stones.
  • Low magnesium - Reduced level of magnesium, a natural component of struvite crystals.

Not recommended in cases of:
Pregnancy, lactation, growth
Chronic renal failure, metabolic acidosis
Heart failure
Use of urine-acidifying drugs

  • Royal canin urinary for cats
    I buy this product on a regular basis. My cat has had crystals in his urine a number of years ago and this product was recommended.

  • Something is different
    My cat has used the original packaging product for years and never had a problem, but since I started feeding him the new packaging food, he has been having diareah and threw up his food. I’m not sure if it’s purely down to the food or my cat has been sick. I’ve taken him to the vet and since changing his diet for a few days, his condition got better. Not sure if anyone else is having similar experiences? I am considering to change to another brand of urinary diet for my cat.
