I would steer clear of anything that says Weathershield since it obviously has been chemically treated in some form. Better to play it safe and not risk your animals getting sick. We are lacking in good scientific research to show what chemicals are safe, and for what species. I've used plain pine and not had that many issues with rotting. It just requires building smartly. And yes there will be some moments when a piece of wood will need replacing. For me it has been worth it in the long run. My tortoise/turtle enclosure has been standing for 16 years.Does anyone have any experience with this wood from Home Depot. I want to make sure it is safe before we start rebuilding our enclosure. Thanks. View attachment 268691
