Will give the cardboard a go. Might create the perfect environment for them :)
I am not a "walk barefoot" kind of person, but I don't mind getting my hands dirty.
There are worse ways to spend your time, like being an evil mother fucker genociding like a demon and raping children, you know?

You don't need to walk barefoot, though I definitely do (though it's getting cold in Vic now!) Getting your hands dirty, well, that's good enough ....
