FLUTD (feline lower urinary tract disease) affects ~10% of AU cats at some point. Struvite crystals, bladder stones, idiopathic cystitis — different causes, but diet is the common intervention. Here's what actually works, split by over-the-counter vs prescription.
Over-the-counter urinary support is fine for prevention; for a diagnosed crystal or stone, you need a prescription diet (Hills c/d or Royal Canin Urinary SO). Wet food inclusion matters more than brand.
Hill's Prescription Diet c/d Multicare
Prescription-only in AU — your vet will authorise. Dissolves existing struvite in ~2 weeks, prevents recurrence. The gold standard.
Best for: Cats with confirmed struvite crystals, recurrent UTIs, or idiopathic cystitis.
Royal Canin Urinary SO
Also prescription-only. Slightly higher sodium content drives water intake. Some cats prefer the taste over c/d.
Best for: Cats who don't tolerate Hills c/d; dissolution of struvite + prevention.
Royal Canin Urinary Care (over-the-counter)
Lower mineral content, higher moisture encouragement. Not a treatment — a prevention formula. Available at Pet Circle, Petbarn without script.
Best for: Cats with no current issue but breed or history risk (male cats, Persians, Maine Coons, Ragdolls).
Hill's Science Diet Adult Urinary & Hairball Control
Balanced mineral content, lower magnesium. Not prescription-strength but safe for daily use across all cats.
Best for: Multi-cat households where only one cat has mild urinary issues and the others don't need prescription.
Advance Urinary Care
Formulated with input from the Waltham Centre. Under-recognised Aussie alternative to Hill's Science Diet.
Best for: Cost-conscious owners wanting preventative support in an Australian-made formula.
Frequently asked questions
How do I know if my cat has a urinary issue?
Watch for: urinating outside the tray, straining without producing urine, blood in urine, excessive grooming of genitals, vocalising while urinating. Any of these symptoms = vet visit within 24 hours. Blocked urinary tract in male cats is life-threatening within 48 hours.
Can I just feed wet food instead of a urinary formula?
For prevention in a healthy cat, yes — wet food + adequate water access addresses ~80% of urinary risk. For a cat with diagnosed crystals or stones, diet alone isn't enough. Prescription food + wet inclusion is the combined approach.
Do water fountains actually help?
Yes, measurably. A 2023 University of Queensland study found cats drink 40–70% more water from a circulating fountain than a still bowl. Cheap intervention (~$50–80) for meaningful urinary health benefit.
