Maybe a couple of questions need to be asked of you snakeboy, 1st one is ...Is space a concern where you are going to house it? and do you have any concerns about power usage for heating?
Womas will climb but are rather clumsy when doing so , so provide some space for this as well as something to climb on. They love to roam and explore at night so the more space the better with rocks ,hides,water bowls ,sand pits, raised sections etc.
This is my experience with my Uluru woma and he loves the sand pit and rolls and digs in it every day. Plenty of people said i shouldnt put a sand pit in it but he loves it and spends heaps of time on it. Here's some pics of him rolling, the sizes 1600x650x500.
P.s. the sand pit is 800mm long then there is a raised platform with marine carpet which is 800mm long in which i feed him on.
