Disclosures: No disclosures to report. Urolithiasis is a common cause of Feline Lower Urinary Tract Disease (FLUTD). The most common feline uroliths are calcium oxalate and struvite. Dietary dissolution is safe and effective for eradication of sterile struvite uroliths in cats. Richness in moisture and/or sodium and/or protein in order to increase water intake and thus to increase diuresis, urinary flow and the frequency of micturition may vary between commercially diets. This prospective, multicenter, randomized, double blinded clinical trial evaluated the efficacy and safety of two new high protein-low carbohydrate dry diets in sterile, struvite urolithiasis in cats with signs of non-obstructive FLUTD. Cats enrolled in the study were randomly assigned either to diet A, 1 formulated to achieve dissolution and prevention of struvite uroliths, or to diet B, 2 formulated to dissolve struvite uroliths. Cats were followed up to 14 days after the uroliths had been dissolved, latest to D56 AE 2. Physical examination, urinalysis, and abdominal ultrasound were performed weekly. Analyses were performed using the software SASÃ’ version 9.4. The significance threshold was set to a=0.05 two-sided.
