I have two faunariums from exo terra where I keep a hatchling in:
The great thing about it is that a third can be seperated with some plastic divider so you can leave the mouse in the same enclosure which then will smell quite good (especially males) and then you can remove the divider once you want to supervise the feed.
I am talking about the PT2310 here btw. - the large one with two openings
