Well

If morning urine of a human is healthy.
If breast feeding of humans is healthy.
If camel milk is healthy (for the knees, so they say)
If goat milk is healthy
if cows milk is healthy
Their Urine must have something equally beneficial as a human, as also these animals give birth and feed their young....

Their piss must have some sort of use, I guess...

In the Netherlands we call this PISS Heineken!!!!
