Ok, so I found a sweet piece of old root system in my woodpile last week, which I brought inside to dry. Yesterday I decided it was dry enough to wire brush, sand and buff out. It's been dead for what appears to be a number of years. Since I want to use it as a centerpiece for my new uros enclosure I wanted to make sure it would be safe doing so, as I know many species of tree emit harmful toxins, especially coniferous trees. I have good reason to believe the root came from what's locally known as swamp cedar, more broadly as white cedar. I know that cedar chips/saw dust should not be used for any animal but I believe that's due to oils and dust being easily inhaled. In this case the wood is in a solid form and resembles drift wood. Anyone have any thoughts or, better yet, actual knowledge in reference to my query? Thanks!
