we are wanting to switch ebony's box from an uncovered to a covered. We tried to two weeks ago with no luck because we wanted to change both the type of box and the location of the box and she got confused. We did switch back to her old box and over the last two weeks changed the location with no problems. Last night we tried to put the top on and she started acting wierd. Any suggestion on how to transition her to using a covered box? Or should we give up on trying to get her to use a box that is covered?
