Is wood finish toxic for a cham? I’m building a cage and was wanting to put a finish on the wood and wasn’t sure if it was safe or not
You don't want to play it too safe with wood sealant imo. If it's not strongly waterproofed the wood will rot and warp. This happened to me and I had to toss my wood enclosure out. Polyurethane should be fine (multiple coats!) and people here also seem to strongly recommend FlexSeal.
