The good news? Diet plays a massive role in prevention. The right urinary food can dissolve existing struvite crystals, prevent recurrence, and keep your cat’s urinary tract healthy long-term. This guide explains what to look for, which brands vets actually recommend, and the difference between prescription and over-the-counter options.
Understanding FLUTD: Why Diet Matters
FLUTD is an umbrella term covering several conditions affecting the cat’s bladder and urethra:
- Struvite crystals/stones: Mineral deposits (magnesium ammonium phosphate) that form when urine pH is too alkaline. Diet can dissolve and prevent these.
- Calcium oxalate stones: Form in acidic urine. Cannot be dissolved by diet β surgery may be needed. Diet can prevent recurrence.
- Feline idiopathic cystitis (FIC): Inflammation without a known cause. Stress is a major trigger. Diet helps but isn’t the only solution.
- Urethral obstruction: A medical emergency primarily affecting male cats. Crystals or mucus plugs block the urethra. Can be fatal within 24-48 hours if untreated.
Signs your cat may have a urinary issue include straining in the litter tray, crying while urinating, blood in urine, urinating outside the box, and excessive genital licking. If your cat cannot urinate at all, this is an emergency β see your vet immediately.
How Urinary Care Diets Work
All urinary care cat foods share these key formulation principles:
| Mechanism | How It Works |
|---|---|
| Controlled mineral levels | Reduced magnesium, phosphorus, and calcium to minimise crystal formation |
| Urine pH management | Targets urine pH of 6.2-6.4 β too acidic for struvite, not acidic enough for calcium oxalate |
| Increased water intake | Higher moisture content (wet food) and added salt to encourage drinking and dilute urine |
| Anti-inflammatory support | Omega-3 fatty acids and antioxidants to reduce bladder inflammation |
| Stress management | Some prescription diets include tryptophan and alpha-casozepine for calming effects |

Prescription vs Over-the-Counter: Which Do You Need?
| Situation | Recommendation |
|---|---|
| Cat has been diagnosed with struvite crystals/stones | Prescription (Royal Canin S/O or Hill’s c/d) β needed to dissolve crystals |
| Cat has had a urinary blockage | Prescription β lifelong prescription diet under vet supervision |
| Cat has recurring FIC/cystitis | Prescription (Hill’s c/d Stress) β with environmental enrichment changes |
| Cat is at risk (male, overweight, indoor, previous episode) | OTC urinary care food as prevention + water fountain |
| Healthy cat, no history | Standard cat food is fine β no urinary diet needed |
5 Tips to Prevent Urinary Issues
- Maximise water intake: Use a water fountain (cats drink 36% more from fountains), offer wet food daily, and add water to dry food.
- Maintain clean litter trays: Follow the n+1 rule β one tray per cat plus one extra. Scoop daily.
- Reduce stress: Provide hiding spots, vertical space (cat trees), and routine. Stress is the #1 trigger for FIC.
- Keep weight healthy: Overweight cats are significantly more prone to urinary issues.
- Annual vet checks: Routine urinalysis can catch crystal formation early before symptoms develop.
Frequently Asked Questions
Can urinary care cat food dissolve crystals?
Prescription urinary diets (Royal Canin S/O, Hill’s c/d) can dissolve struvite crystals in 5-12 weeks. Over-the-counter urinary foods help prevent crystals but cannot dissolve existing ones. Calcium oxalate stones cannot be dissolved by any diet and require surgical removal.
Should I feed wet or dry urinary care food?
Wet food is strongly preferred for urinary health because it dramatically increases water intake, producing more dilute urine. If your cat only eats dry food, add water to the kibble and ensure access to a water fountain. Many vets recommend feeding at least 50% wet food for cats with urinary issues.
Can I feed urinary care food to my healthy cat?
OTC urinary care foods (like Royal Canin Urinary Care) are safe for healthy adult cats. Prescription urinary diets should only be used under veterinary supervision as they significantly alter mineral intake, which could be inappropriate for cats without urinary issues.
