I think it's important to remember that an outside 'room' isn't a room that's 10'x10'. If I were to GUESS on the size I would say they were probably 500m x 500m (uh.. 0.31 miles or 1,640 feet) or so at the minimum.
You have to consider that entire castles are built on them, towns, mountains, are some pretty extensive areas.
Of course it doesn't scale properly but I think that's the same reason that a rune doesn't trigger outside. The 'room' is simply too big to trap the entire thing.
Also the same reason (at least in my head) that you can't 'peer' on the world map.
It's totally possible that the wolf and rabbit are far apart. Or that the wolf is simply not hungry.
That said, I think it would be interesting if they DID occasionally fight.
