i had planned to use twenty gallon long tanks that were built with half glass and half screen tops, and front sliding doors. i was going to use plywood to encase the bottom, back and sides - but - i've chosen to use http://www.showcasecages.com/ products instead, even for breeding. they are really the best! hands down!!!http://www.showcasecages.com/

and cagesbydesign.com also makes great enclosures if you want something more natural, i think they have python kits...just ask them...http://www.cagesbydesign.com
