Morty, five minutes after being put back in a clean cage with a brand new cave to replace the one she kept tearing up: "I am in a strange, new place. There may be danger. Those worms are probably poison."
psst, @fernfren, I know you don't want to miss the Morty pics :).
@fernfren This gives the pill bugs a place to dry out (no moisture below the roof), enter the substrate through crevices. The retaining wall keeps her from getting to them if they are in the soil on that side. She can't get them if they wander above or on the other side, small stones discourage her from digging there. She can hop up the bridge to dig, but she is a lazy thing and will need to be quite hungry to do so. 2/?
