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

  • Excellent product
    I cannot express my thanks enough. My little cat was so stressed because I had taken in my granddaughters Akita. My tiny house became a war-zone. Once I started to feed her the urinary diet, she took control and everything was great. Her infection cleared up very quickly, and her fur shined once again. Thank you

  • Works for our cats!
    One of our cats almost died from crystallisation problems when under a year old. This dried food was recommended - he’s been eating this for ten years now and is still going strong!

  • Healthy cat
    This product was recommended by our vet when some years ago our cat was suffering from frequent urinary problems.Along with the Royal Canin urinary wet food pouches this has been the solution and she is now a spritely 17 years old. Easy to order with MedicAnimal, prompt delivery, good discounts.
