Get two 2 story ferret nations, but don't put the right bottom side panel in on the left cage, and don't put the left bottom side panel in on the right cage. Push together...you're done! Actually, put down a piece of plastic or signboard under where the two cages meet (under their trays) to keep litter or food from falling down. This is our setup and it does that number just fine. Also, if you have fighting or sick fuzzies, you can isolate them by hooking up the ramps of the top levels, a feature of the Ferret Nation. So you could technically have one big cage that can in seconds be separated into one large part and two equally smaller sections. That's why I leave the top side panels in.
