Which urolith is becoming quite common in cats?

• A. Oxalate
• B. Silica
• C. Urate
• D. Cystine

Answer: (A)

Calcium oxalate stones have become more common in cats. These stones form when urine contains high levels of calcium or oxalate, and they show up clearly on standard X‑ray images because they are radiopaque. A key implication is how they are treated: unlike some other types, calcium oxalate stones can’t be dissolved with dietary changes or urine pH adjustments. Management typically involves removing the stones with surgery or lithotripsy, followed by long-term strategies to keep urine dilute and limit oxalate and calcium intake to help prevent recurrence. While other urolith types exist—such as silica, urate, or cystine stones—they are far less common in cats, which is why calcium oxalate stones stand out as the more frequent problem lately.
