BENEFITS: STRUVITE DISSOLUTION -Provides nutrition that aids in the management of pure struvite uroliths MODERATE CALORIE -Moderate calorie content, 14% less than Feline Urinary SO morsels in gravy, to help maintain ideal weight. URINE DILUTION -Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals LOW RSS -Relative Supersaturation (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. S/O Index -This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.
