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 a cat's urinary health. In fact, s/d is clinically tested to dissolve struvite stones in as little as 6 days (average 13 days). This dry food has a chicken flavor and an irresistible taste that cats love.

How it works:

  • Controlled minerals and optimal urine pH
  • Optimal target urine pH of 5.9 to 6.1
  • Controlled magnesium and phosphorus

How it helps:

  • Dissolves struvite stones in as little as 6 days (average 13 days)
  • Increases solubility of struvite crystals, aiding in dissolution
  • Minimizes urinary concentration of struvite building blocks

Additional info:

Hill's Prescription Diet s/d Dry 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 a cat to continue to enjoy a happy and active life.
