Whenever anything around the house is going to be destroyed or thrown out I always think "can I use that for the lizards somehow?" While moving some old railroad ties around my house I thought they would make great hides for the tegus. I used old fencing panels for the top, left over plywood, and the ties for the base. The hide itself is about 5'x3', with lots of mulch and hay and the red tegus took to it immediately. Once the weather cools down more and the tegus no longer come out of the hide during the day I will cover the hides with plastic and wait for spring to see them again.
