Royal Canin Urinary SO Moderate Calorie for cats is a complete and balanced diet used for cats with or at risk of developing feline lower urinary tract disease and predisposed to weight gain, to help dissolve pure struvite uroliths, and help prevent struvite urolithiasis, calcium oxalate urolithiasis, and calcium phosphate (brushite) urolithiasis. This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals. • Moderate acid load encourages production of urine with a pH between 6.0-6.3 • Increased sodium chloride content to increase thirst and promote formation of a dilute urine • Moderately restricted magnesium and phosphorus levels • Controlled levels of calcium and oxalate • Increased levels of potassium • Enriched with a special blend if antioxidants to help maintain a healthy immune system • Enriched with long chain omega-3 fatty acids eicosapentaenoic and docosahexaenoic acid (EPA and DHA) to help modulate inflammatory reactions.
