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

    My cat Nancy loves these to go with her Royal Canin dietary wet food

  • Royal Canin VHN Feline Urinary S/O
    Our vet recommended this product as our female cat had cystitis and had issues weeing. Her behaviour was irratic and she was obviously distressed. The first bowl of the Royal Canin was literally demolished in minutes and from then on, she has loved it and clears her bowl every night. Her problems have disappeared in just 4-6 weeks and she doesn’t even need to use her litter tray anymore as she is happy to go outside & she was using the litter tray every few minutes previously, poor thing! & Great product, happy cat! Although not the cheapest food you could ever but your cat, we think her happiness and wellbeing is worth every penny.

  • Excellent service, excellent product.
    This product really suits my cat, she loves it. Her vet says if he didn't know better, she would pass for an eight-year-old when in fact she is almost sixteen. Ordering is very easy and there is always quick delivery.

    Great product that we feed our cat with to ensure our cat has healthy kidneys

  • 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
