We're having construction on our house, and there is a whole pile of sand outside my door..just calling me to take some. I think it's silica sand...isnt that what they use for construction? I've heard it's good, and I've heard it's bad. I dotn even know if it's silica sand! But my cages are not all sand, it's half carpet and half sand...can I use it? Thanks in advance!
