Calcium carbonate crystals are often seen in which species?

Explanation:
Calcium carbonate crystals in urine form when urine is saturated with calcium and carbonate and the pH favors precipitation. Horses routinely have alkaline, calcium-rich urine due to their forage-based diets, so these crystals are frequently observed in healthy equine urine sediment. In dogs and cats, other crystals (like calcium oxalate or struvite) are more typical, and calcium carbonate crystals are not as commonly seen; cattle rarely show them. That combination makes the horse the most likely species to exhibit calcium carbonate crystals in standard findings.
