I have a 3X4 with a 2X3X1 loft for my one Guinea Pig. It has been a while since he has had a friend to play with so I'm looking to adopt another pig. If i used the loft as a quarantine cage, would it be large enough? Also, would they be two close together if I I kept the loft attached or should I separate it and move it to another room? Thanks in advance.
