No, I would not use either in a chams cage. Philodendrons are toxic if eaten (although so are golden pothos to a certain extent, so that's something to consider if your cham is a plant chewer), and pitcher plants are just too delicate and full of gross junk in the trunk, so to speak.
Sorry, not trolling. I had just been to the plant store. See I am getting ideas about what the limits of my system are. I have kept houseplants for over a decade and living in Colorado a lot of the tropical stuff is hard for me to grow. Now with the Cham cage I have a great micro environment for other stuff I have wanted to keep. Just have to check if its safe or not.
