I already asked this on another forum, but I figured might as well ask here also since it has to do with building....the other day I picked up some big (30-48"x15-20" flat slabs of either pine or redwood bark (i think redwood) from a local national park. I want to know if it would be all right for me to use these as backgrounds in a viv I'm making for my female Cal. king. I know it's not a good idea to use redwood bark shavings as bedding, but I'm just goin to silicone this stuff to the back wall to simulate a tree trunk or something. Does anybody know if this could work without hurting my snake? Thanks
