FLUTD (Feline Lower Urinary Tract Disease) is a complex disease of the lower urinary paths which is often related to crystal creation in the urinary tract, a painful condition for many cats. The two most common types of crystals that form in the urinary tract of cats are struvite and calcium phosphate. Hill’s Prescription Diet Feline c/d Multicare Urinary Care with Chicken can help to reduce the formation of both types of urinary stone. Struvite crystals and stones usually develop from a combination of urine saturated in magnesium, ammonium and phosphorus and alkaline urine pH. Hill’s Prescription Diet Feline c/d Multicare Urinary Care with Chicken promotes a healthy urinary tract and reduces the risk of recurrence of urinary stones.
