Hi there.. I assume you mean a Kenyan sand boa. I have two.. they're pretty easy to keep.

You want a similar temp/humidity as for ball pythons, but since sand boas are burrowing snakes, you don't want newspaper, instead use something they can dig in. I use aspen shavings for mine. Just don't use pine or cedar, as they will cause respiratory distress.

If it's a young one, you want to keep it in a pretty small enclosure too.
