Hi everyone. So I am working on make a enclosure for my boa. I have left over sheets of plywood from when we made the barn for my horse. It is the "flakeboard" kind of plywood. Dimensions I want to make are 5' x 2' x 2'. It's going to be in my bed room so I can't make it overly huge. And as of now she is only 3 feet and slim. My question, what would I use to seal the wood? What about the edges, would I use caulk? I plan on drilling holes (small ones of course) in it for airflow as well. Any input is welcome.
