Bladder stones are collections of mineral crystals that combine together in the urinary tract. They can cause discomfort and lead to more serious problems that require the care of a veterinarian. Hill's nutritionists & veterinarians developed Prescription Diet s/d clinical nutrition to support your cat's urinary health. In fact, s/d is clinically proven to dissolve struvite stones in as little as 6 days (average 13 days). This wet food has a irresistible taste that your cat will love.

How it works:

  • Promotes desirable urine pH levels
  • Low magnesium & phosphrous levels

How it helps:

  • Increases solubility of struvite crystals, aiding in dissolution
  • Minimises urinary concentration of struvite building blocks

Additional info:

Hill's Prescription Diet s/d Cat Food is intended for intermittent feeding only and is not recommended for long-term feeding (over 6 months). Please consult your veterinarian for further information on how our Prescription Diet foods can help your cat continue to enjoy a happy and active life.
