For my (very near) future GBB, I know they are okay for a while without food (any tips on what to feed before leaving them? A bigger meal I guess? Something like a mealworm left in case they get hungry?)- so going away for a week should be no problem when we do- but as for the water... what if the water evaporates or they web over it while away. Can anyone who has to leave their T's for periods of time share any tips with me? Thanks in advance.
