The other day my husband brought home a Midwest gp cage for me. Love the cage and all, but my 2 piggies won't leave the kitchen. They know how to use the ramp bec I put them on the ramp and they walk over to the other side. I will leave the room and walk back in and they are back in the kitchen area. Any ideas on how to get them to go both places? Or should I just remove the divider and then they can roam the whole cage? I don't want to close them off from the kitchen area, so I am at a loss right now on what to do
