I'm building a 4'x8' indoor enclosure for my redfoot torts. I've water sealed the wood with Thompsons (will cure for at least a week) but need a solution for a removeable liner. When it's time to change the mulch, I'd like to be able to take out the hides, etc, and just lift out (with help) a liner or tray(s), carry outside and add to my garden. Any easy solutions anyone?
