Hey guys, I have a run that has a sand floor in it that smells to HIGH HEAVEN. I clean it out regularly, etc so I realize that sand isn't the answer for me. I thought when I put it in that it would stay dry since my run is covered, but no. It gets soaked. Regularly. And then it smells terrible. So does anyone know of something I can put down instead of sand? I thought maybe pea gravel, but that would be hard to clean. And mulch gets very hot in the south. What are your opinions?
