hi, i am no expert but my two babies bella and mickey are 13wks and what we do is put them in two seperate metal cages (30x42)side by side. they both have their beds at one side and paper at the other and clip on water bowls. they are able to lick each other through the bars and say night night. they like their own little houses. during the day if we are in we leave the doors open so they can come and go as they please. think it would be good if your babies could have their own little places.they might cry at first but stick with it, it does get easier
