Hills Prescription SD Diet Feline Dry is for the nutritional management of pets with urinary tract disease,

Urinary tract disease is often caused by the formation of mineral-based crystals and stones in the urinary tract that can cause discomfort, bloody urine and even life-threatening obstruction.

For cats, struvite crystals are often the cause of urinary tract disease.

Hills S/D diet has been formulated to help dissolve struvite crystals and stones alleviating the discomfort. Struvite forms as a result of urine that’s saturated with protein, calcium, phosphorus and magnesium combined with an improper urine pH.
