Royal Canin Veterinary Diet Urinary SO Moderate Calorie Dry Cat Food

Lower urinary tract disease (LUTD) refers to a group of disorders that commonly leads to irritation of the urinary tract and corresponding undesirable clinical signs. What causes Lower Urinary Tract Disease? In cats, bacterial infections are far less common. Urinary crystals and stones are often linked to this disease. The most common cause of Lower Urinary Tract Disease in cats is idiopathic cystitis. This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

Key Benefits

  • Recommended for cats at risk of developing lower urinary tract disease and who are predisposed to weight gain
  • Moderate calorie content, helps maintain ideal weight
  • Dissolution of pure struvite uroliths
  • Help prevent struvite, calcium oxalate and phosphate uroliths
  • Provides nutrition that aids in the management of pure struvite uroliths
  • Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine; RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals
  • Reduced level of magnesium, a natural component of struvite stones

Go Mr. Chewy I have got to say that I wish I knew about Mr. Chewy a long time ago. Service is excellent with great prices. I love the fact that I don't have to keep running to Petsmart to find them out of stock of what I need. I have recommended Mr. Chewy to others and will continue to do so. June 28, 2012
Great product for my cats. I bought Royal Canin Veterinary Diet Urinary SO for my cat who developed an UTI. He loves the food. I decided to also try it on my other cats. They all love it also. I continue to receive it for my cats. I do ensure to give only the recommended amount to help my cats with their weight. It is a great product. September 3, 2012
Great for cats with urinary tract issues Good dry RX food, especially for my neutered 10-year-old , who has a history of urinary tract infection. July 5, 2012
Good for weight reduction My cat had gained weight over the last year and has a history of urinary blockage, I was feeding him Royal cannon SO, my daughter who is a vet tech suggested I switch him to the moderate calorie SO. I discussed it with his veterinarian and he agreed. I was afraid he would not like it as well but surprisingly he never noticed the difference. He is on his way to his former svelte self and much more active. I am very pleased with this product. January 8, 2014
