Why Urinary Health
What are urinary crystals and stones?
Feline urinary crystals are tiny mineral particles that can stick together and form stones. The most common types are struvite (magnesiumammoniumphosphate) and calcium oxalate. They form when the urine becomes too alkaline or when theres excess magnesium and phosphate. A healthy diet keeps the urine slightly acidic and low in those minerals, which is why best urinary cat food matters.
When should you worry?
Typical red flags include frequent trips to the litter box, straining, bloodtinged urine, or accidents outside the box. If you notice any of these signs, its time to look at the food bowl first.
