I already have a cage large enough for a full grown at my mom's house, I need a cage for my dad's since the lizard is coming back and forth with me. I already spent A LOT of money on the first cage and am looking for some more cost effective ideas for the second one. I'm not much of a builder, I want to get the 8x4x4 needed for the adult. I'm doing extra work to make money, but I also need to pay for double the lights etc.
