This is George's home. He is an 80# Sulcata.
It is very simple. I chose an area with soft dirt for him to be able to dig, stacked several large logs on each side, laid poles across to support the roof, and then laid pieces of plywood for the roof. I then covered the whole thing with dirt and straw. It's a work in progress, and I'm not done yet.
There is alos a hook inside for a heat lamp if I ever need it. He loves it and had dug quite a burrow inside.
