• Prioritize urate prevention over struvite because sterile struvite dissolves rapidly in cats and protocols for urate dissolution are not available.
• Make adjustments in therapy to minimize struvite without opposing therapy to minimize urate (e.g. feed canned therapeutic foods or add water to decrease urine specific gravity (≤1.030), and medications (antibiotics to control infection-induced struvite, when present)).
• With recurrent stones, first consider therapeutic foods to dissolve struvite (e.g. c/d multicare, others) which are effective when recurrent stones are primarily composed of struvite.
