I am using sand and I hate it! I was told it didn't stink and it was easier to clean. Maybe I messed up when I got play sand instead of the all purpose sand, but the dust is HORRID! My porch is coated with a layer of dust in less than an hour of my cleaning it all off and sweeping the floor. Sadly, I can not change it now - I have 300lbs of it in my 6x4' brooder. Also, it still stinks and I had to go buy a $10 reptile poop scoop to clean it. I am sure some screen over my horse poop scoop would have been cheaper and much easier to use... Still. I would love to go back to the shavings after this!
