If a 18x18x18 is almost the same size thats great I actually found a local pet shop and found a 24x18x18 or a 24x18x24(WxDxH) but for now I have a ruber maid container that is 6inch deep with bedding, 20" long and 14" wide so I think that that should be good enough. Yes I did drill out a butt load of breathing holes. The top is half holes, then I cut a 1/4th of the middle of the top oof and put in a removable screen that IS excape proof( less he can loosen bolts
) and drilled 3 sides of the bottom half. All I need to do now is hook up a light and get the cornny. If there is and problems with this I would like to know because other than that I'm going to go get him today or tommorrow morning and yes I have made the hole cage up for him. It has bedding(can't remember name ontop of my head) a hide rock, Half log, swimming bowl, drinking bowl, and an asort ment of minut plants oh and some pebble rock that have been in VERY HOT water soaks for there 3rd time. Like I said if this is not right plz tell me other than that Im off to work thank
