2025 Expert Guide: Top 5 Veterinary Prescription Urinary Tract Diets in Canada — Vet-Recommended Options to Reduce Feline UT Recurrence (Which One Fits Your Cat?)

Published on Wednesday, August 20, 2025

Veterinary prescription diets formulated to manage and prevent feline urinary tract conditions by controlling urine pH, mineral content, and urine concentration. These diets are typically used under veterinary guidance to dissolve struvite crystals, reduce recurrence of stones, and support bladder health through targeted nutrient profiles and controlled moisture levels. In the Canadian market, pet owners often prefer prescription urinary diets because they combine clinical evidence with convenience: trusted veterinary endorsement, clear feeding protocols, and availability through clinics and licensed retailers. Other consumer drivers include palatability for picky cats, options for weight management or stress sensitivity, and the ability to choose between dry and wet formats for hydration strategy. Cost, provincial availability, and the need for a veterinary prescription also shape buying behavior, with many Canadians choosing products that balance proven clinical performance and day-to-day ease of feeding.

What the Research Shows About Prescription Urinary Diets

Clinical research and veterinary practice reviews indicate that targeted urinary prescription diets can be effective tools for managing feline lower urinary tract disease. Studies and clinical trials have demonstrated that diets designed to dissolve struvite crystals and reduce urine concentration can lower recurrence rates of some urinary crystal types when used alongside veterinary monitoring. Evidence also highlights the importance of individualized plans: diet works best when combined with regular urinalysis, increased water intake (including wet food or water adapters), and management of contributing factors like obesity and stress. While prescription diets are not a cure-all, the body of peer-reviewed veterinary literature supports their role as a core component of medical management for many cats with urinary conditions.

Struvite dissolution: Formulations that control urine pH and reduce struvite-forming minerals have shown measurable crystal dissolution in clinical cases when fed consistently under veterinary supervision.

Recurrence reduction: Long-term follow-up studies and clinical case series report lower recurrence rates of certain urinary stones in cats maintained on appropriate prescription diets compared with historical controls.

Urine concentration and hydration: Diets that promote lower urine specific gravity through increased moisture or formulation changes help reduce saturation of stone-forming minerals; increased drinking behavior and wet food are complementary strategies.

Stress and behavior factors: Specialized formulas that address stress-related urinary disorders (for example, diets with behavior-modulating ingredients or defined feeding plans) can improve overall outcomes when stress is a contributing factor.

Compliance and palatability: Real-world effectiveness depends on owner and cat adherence; trials frequently note that palatability and ease of feeding are key to sustained success.

In Canada, prescription urinary tract diets remain an important veterinary tool for cats prone to urinary crystals, stones, or recurrent lower urinary tract issues. The five options highlighted here — Royal Canin Veterinary Diet Urinary SO Dry Cat Food, Hill's Prescription Diet c/d Multicare Urinary Care Cat Food, Purina Pro Plan Veterinary Diets UR St/Ox Urinary Cat Food, Royal Canin Veterinary Diet Urinary SO Moderate Calorie Dry Cat Food, and Hill's Prescription Diet c/d Multicare Stress Urinary Care Cat Food — cover a range of clinical goals from struvite dissolution to weight control and stress-related urinary management. For most cats and owners looking for a balance of clinical evidence, availability across Canadian veterinary channels, and consistent results, Hill's Prescription Diet c/d Multicare Urinary Care Cat Food stands out as the best overall choice on this list.
