Is there "fencing" material I should stay away from when building a tortoise enclosure? Like certain types of stone or wood?I decided to keep my sulcata foster so need to make plans for her permanent home. So I am going to be perusing everyones pictures to get ideas. Also, I have a 4 car insulated garage where I planned on keeping her in for the cold indiana winters. Can anyone point me in the right direction for some pointers, or ideas for an indoor pen? Or maybe pitfalls to avoid.....I have a basic idea, but any and all feedback is appreciated greatly!
