sorry to hear that! with winter here...they might not try to get outside....keep on looking!!! I sealed my critter room so there are no cracks, nooks, or crannies (after my only albino red sider escaped and the neighbor kids killed it....) my kids are the only ones allowed in my critter room, no friends unless I am here and go in with them....I tell them it's my critter room, not a zoo.
