Each piece is dried, mounted in a clear trophy case and marked with the type of rhino that produced it.
The auction ends Sunday and as of Thursday afternoon bidding had been light, with the top bid for Sumatran rhino poop standing at $500. Black rhino poop was standing at $255, Indian was at $250 and white was at $122.50.
