My new AP cage just arrived today and I have a few questions before I start setting it up. I have read all of the guides on here and they were extremely helpful, there are just a few questions I have left.

1. when I use foil tape to affix the UTH to the outside, do I just cover the edges, or the whole thing?
2. Do I remove the plastic sheet that protects the sticky side of the UTH first?
3. What is the best thing to use to lift the cage enough for the UTH to breath? I was thinking furniture coasters, but they are only about 1/4 an inch thick.
4. Will the fumes from the sealant affect my snake while it cures (I live in a tiny three room apt with no doors so the fumes are strong there is no way to close off the snake from the smell).
