Just wanted some input on ferret rooms or total house proofing for those who let their babies run free in the house 
Im thinking of letting my future babies be free roam when we're home but have a good size cage for when we're out.  We would be living in a 1-2 bedroom apartment with a dog and two small pets

Does this work for anyone? How did you set up? Would ferrets be able to safely use those ramps/boards some people have on their walls for cats to walk on? or are they too rambunctious? Any other ideas for safe multi levelling of your ferrets space?

Would love pictures!
