Hi, so I am building my tortoise a new enclosure out of a dresser! It has three shelves inside, with sliding glass doors to close it. I want to make all three levels usable for my sulcata tortoise, so that means building something like stairs that she can climb! I just don’t know how to build it with out them being to steep or what to build it out of! I am hoping some type of expert can help me!!! If y’all want pictures I will post them!
