They like pooing outside their tank...
When i have had my corn out and am putting him back in, i just open the top hatch and place him on the top, so he can go in of his own accord. Yesterday I put him on top and just before going back in, he stuck his ass over the outside edge and crapped in my printer! (The tank is on a shefl next to my PC). Now every sheet i print has a big smearing of snake poo down it :eek1:
