We have 13 fuzzies right now in three 5 X 3 X 2 wire cages that I have connected using 4" rubber tubbing and home outside dryer vent housing. The wire cages are getting old, bent, and just not sturdy anymore from all the movement when it comes to cleaning. I am looking at the Ferret Nation Cages, specifically the 142 dual level. What the maximum fuzzy count per cage? 2? 4? Thanks! [Posted in FML 6361]
