WHAT I DID WHEN MY LEOS WERE OUT... my cat got into the room and opened the tank and got 2 leos out....on different days.... i used plastic soda bottles... cut the top off and stuffed the bottle with moistened moss after a few hours i found them in the "humid hides" also a lil plastic bottle with holes and mealies and crix inside... havent tried that, but my leos get excited when they see the mealies and crickets moving around. hope something has helped you
