I am looking create a large outdoor habitat for my semi-arid tortoises (they are in a smaller one right now), and would love to build those natural looking caves/dens you see in zoos and wildlife parks. I have a lot of river rock of all sizes available, and am hoping that if they have nice cool dens they won't need to burrow too much. I have not been successful in finding anything on the net. Does anyone have any ideas on where I can find this info?
Thanks much!
