Wonderful stuff. I put it in a plastic container int he enclosure to keep it somewhat contained. Of course my snake would daily flip the thing like a table but it was still easy to take out and spot mist. Of course now that I have the humidity generating monster that is a PVC enclsoure, not sure if that is needed anymore. On a side note... DO NOT put any wet/damp/not completely dry substrate in a pvc enclosure!
Good to know, i was actually looking at pvc cages as Germaine Is just about to grow out of the one I currently have her in
