DrBlack, are you calling me (gasp) "old"?!? The thing you need to remember about cages, is that they all have doors and doors are meant to open AND close as we want. Figure out why you closed the door and what thing(s) on the other side of the door mean enough to you to get you to open it again, and you will have the key. And yes, although it is a shame about your sweet ride, and I can commiserate as I felt the same when I trashed my favorite t-Rex, the important part, YOU, survived. So sayth the little old lady lol.
