Also,

Any plants that you decide to put into the cage, make sure they aren't poisonous to turtles. I think that turtles can eat almost anything. I'm not sure about that though. I've read that they are immune to all mushrooms. I've seen Igor eat mushrooms on a walk through the woods. He was fine afterwards. Turtles can choke on things though. Luckily that has never happened to Igor or Izzy.
