is a great dirt mixture. You need to play with it though (which is fun in itself let me tell ya, haha). I mix playground sand and plain ol' dirt to find a mixture that will enable my savs to dig (as they are naturally inclinded to do and are MUCH happier being able to) but also holds it's shape when they dig tunnels. :) If you have dirt in your yard or area that has a good amount of clay this helps. ;) Like most monitors (as I mentioned above) savannahs (bosc) monitors LOVE to dig.
