Struvite & Urine Acidification
Struvite crystals form in alkaline urine. A diet that acidifies urine and lowers mineral saturation belongs only under veterinary guidance.
What is it?
Struvite is a mineral that can crystallise in cat urine when urine is too alkaline and enough magnesium, ammonium and phosphate are present. Struvite grit and stones can irritate the urinary tract and cause pain when urinating.
Why does it matter?
If your cat visits the litter box often, passes only small amounts or goes outside the box, that can point to urinary issues. Struvite is a common cause. But not the only one. Only a vet can determine what is going on with testing.
How does it work?
Struvite diet food works mainly through urine acidification, so existing struvite can dissolve, and through lower mineral saturation of the urine, so new crystallisation has less chance. Research indicates that urine pH weighs more heavily than magnesium intake alone. Balloxx Anti-Struvite is a complete diet food formulated within that framework, not everyday kibble to feed "preventively".
Benefits
- Urine acidification supports dissolving struvite grit
- Lower mineral saturation helps limit recurrence
- Complete diet food, no separate supplement needed
Misconceptions
Anti-Struvite is not standard cat food for healthy cats. Use it only when your vet has confirmed struvite or prescribed a urine-acidifying diet. Without a diagnosis, the wrong food can do more harm than good.
