I just found a new SCN on craigslist, I offered $75, and they said yes! They got it for their guinea pigs, but it was too small. I'll be picking it up in the next few days, as soon as I can get my boyfriend and his truck, lol. The baby boys will be so happy!Quick question: can I place the new cage on top of the other SCN? Like if I take off the stand and some how tie them together? I obviously want the boys and girls separate, but want the double critter nation look. I figured the cage should be heavy enough that I can stack it and not have to worry about it falling off. Any ideas or opinions?
