Which is the most common type of urinary stone in cats and dogs?

• A. Struvite
• B. Calcium oxalate
• C. Urate
• D. Cystine

Answer: (A)

The main idea is recognizing which mineral composition shows up most often as a urinary stone in small animals. Struvite stones form readily in urine that is alkaline and contains magnesium, ammonium, and phosphate. In dogs, these stones commonly arise when a urinary tract infection with urease-producing bacteria raises urine pH and promotes struvite crystallization. In cats, especially younger ones, struvite stones are also commonly seen and can often be managed medically with urine-acidifying diets and addressing any infection. Because this type is encountered more frequently across both species than the others listed, it is the most common. Calcium oxalate stones are a frequent alternative, but they are not as prevalent as struvite and often form in different urinary conditions. Urate stones are tied to specific issues like liver disease or certain breeds and are less common. Cystine stones are rare and usually genetic.
