My WTF has recently started trying to burrow. We had to move the water bowl back away from the wall because he had shoved himself head first in between it and the wall. He has never done this before. The temp in his cage stays at around 75-80 degrees. (Depending on where in the tank he is) and the humidity gage stays at a constant 60%, maybe a little more. He is still eating well, and climbs around his cage. Any suggestions? Has anyone ever seen this behavior before? I also just noticed him rubbing his nose in the corners of the cage.
