Hill's Prescription Diet c/d Urinary Stress is a veterinary wet food for adult cats managing feline lower urinary tract disease with a stress-related component. Available as single 85g portions or 12-packs of pouches, it is a complete dietetic food that requires a veterinary prescription. Chicken is the primary protein source.

The formula is clinically tested to dissolve struvite crystals and reduce their recurrence by correcting the mineral imbalances — excess calcium, phosphorus, and magnesium — that drive crystal formation. It also addresses the stress-triggered dimension of FLUTD, a recognised precipitating factor in many cats. The wet format contributes to urine dilution through dietary moisture, which is an important management factor in urinary disease.

c/d Urinary Stress is typically used as an ongoing dietary prescription following a FLUTD diagnosis, often alongside regular veterinary monitoring. The wet pouch format is particularly useful for cats that drink little water independently, since concentrated urine promotes crystal development.
