Just drop them in their cage when you get one, and they'll understand to poop in it - the only caveat is that you have to do something like locking them back into it every night so they understand it's their home, otherwise if you leave them out 24/7 they'll shit under furniture and stuff and not just in their cage
Otherwise, you can let them run around all day. They'll enjoy it.
