My vagans (skillet) is always remodelling her hidey making new tunnels and entrances closing off old ones etc. One morn I walked in and she was nowhere to be seen. Looked in her hidey wasn't there...hmmmm no sign of any new burrows and so forth. Poof it was like she was gone! I knew she couldn't get out but it crossed my mind. I lightly brushed the substrate which is completly matted over. Sure enough there was a skittering! HAHA reminded me of tremors! I guess it freaked her out more, cause when I lightly lifted one side up she bolted out and landed squarrely in her waterdish! Needless to say she has no more interest in venturing under her mat anymore.
