This week I moved my tort back inside for the winter since it was low 40s overnight. Before bringing her back in, I upgraded her indoor enclosure by adding a digging area with 2ft of substrate. When I brought her inside, she ate some greens, found her way to the new area, and burrowed in. Its now been more than 24 hours without her coming back out (as far as I know, but I was at work for 8 hours yesterday so its possible she surfaced, but she didn't eat anything if she did). Is this cause for concern? Should I dig her up? The ambient temp in my house is around 74 F.
