There is magic armor, magic weapons, and magic items that all operate differently than their real life counterparts would. I feel that assuming there is some kind of magic involved with presumably experienced hunters capturing a high level monster makes sense, and that they would have the resources to own a more expensive, potentially lightweight yet sturdy cage than novice hunters would makes sense as well.
So, in other words, it might be some kind of partially levitating cage? So that when the MitD is in it, it only weighs about 10 pounds from the viewpoint of someone lifting it?
