While at the reptile show today I heard one of the vendors taking to a buyer about a species of python that likes to climb (I think he said carpet python but it was loud) anyway, he said that in some of his larger cages he fixes white plastic pvc pipes to the ceiling of the cage to act as hides. I thought that sounded really cool, esp since they come in so many shapes, but I was wondering if these plastic things were the same kind of PVC as the cages. My dad used to do some construction and these pipes stink when heated, so I was curious to see if any one had used something like these for hides or burrows (for any species)?
