What type of urine is typically cloudy in horses and rabbits?

Horses and rabbits are known to have cloudy urine due to the presence of calcium carbonate crystals. This cloudiness is common and considered normal in these species. Calcium carbonate is a type of crystal that can form when urine is alkaline, which is typical in horses, and these crystals can cause a cloudy appearance without indicating any pathological condition.

In rabbits, similar cloudiness can also result from the excretion of calcium carbonate, as their diet often leads to higher concentrations of this compound in urine. The presence of these crystals is a normal finding and does not suggest any underlying disease or health issue.

Other options do not accurately represent the typical characteristics of horse and rabbit urine. Concentrated urine with high specific gravity might suggest dehydration or other conditions but does not specifically correlate with the typical cloudy appearance caused by calcium carbonate. Clear urine with no crystals would not apply to horses and rabbits under normal circumstances, as their urine generally contains these crystals. Brightly colored urine does not reflect the common attribute of cloudiness associated with calcium carbonate either and could indicate other issues if present, but is not typical in these species.
