A while ago my tarantula, Aranea, tried to dig herself a burrow (twice), but ran into the wall both times. She buried her old water dish with the first one, but those were the only problems. She really liked to sit in them (and "sun" bathe in one). But recently, she's been trying to climb to wall over there, and she's made it all the way off the substrate. She doesn't seem to be doing it in a stressed way. I'm worried that she might fall and hurt herself, because she's not a climbing tarantula. So, any suggestions?
