Can You Potty Train a Cow

A small herd of cows in Germany has learned an impressive trick. The cattle use a small, fenced-in area with artificial turf flooring as a bathroom stall.

The cows’ toilet training talent isn’t just for show. This setup could allow farms to easily capture and treat cow urine — which often pollutes air, soil and water. Nitrogen and other components of that urine could be used to make fertilizer.
