so how did you solve the freight??? any tips for the rest of us?
as to the gap between the doors issue - it certainly is an issue, and I probably worry about it too much. For all my smaller adults I actually put a double folded strip of cardboard between the doors to eliminate this isse. It is double folded so it fits in there so tight they can't push it out. I attach a small tab to it sticking out so I can easily pull it out to open the doors or or it can be difficult to get hold of. The corns know that is a way out of the cage, they can feel the air coming in through the gap. During breeding season you can see the males running thier noses up and down the gap.
A final point - when you get the cages - run your hand around the rim that is above the door at the front. There is a rivet centrally on this small ledge. Despite the limited width of this ledge, the snakes do seem to like to go up the sides and along the top, and some of them make it down the other side and some of them fall off. I have one large male who always falls off with a lot of noise, and I even pile up extra aspen at the front to cushion his fall. However, my point is that the rivet can be rough - feel it by hand to check, and on some of the cages, I have put tape over it to save the snakes ripping their scales/damaging themselves as they push their way along the ledge.
One funny point - when I first started using visions I didn't know they could get onto that ledge, and I was looking for one of my girls and she wasn't in either hide, and I was lying there panicing - head in the cage rummaging through all the aspen and suddenly she fell off the ledge onto the back of my neck! I don't know who moved faster.
