INTEGRA PROTECT Urinary Struvite Cat Food has been specially developed for cats to prevent the recurrence of struvite stones. Balanced mineral content and a needs-based supply of magnesium and phosphorus ensure a cat urine pH value of < 6.5. At this pH value, struvite stones no longer form. This diet food is made without grains and is therefore suitable for cats with a grain allergy.
