Wire cages with levels are what ferrets prefer. Caging protects the ferret as well as your house. Ferrets are inquisitive, fearless, and capable of getting into places that you never imagined. If their head can fit into something, then the body can follow. To ferret proof your home, we suggest that you start with getting potted plants out of their reach.
Ferrets love to dig in dirt.
Ferrets can not climb in the sense that cats can. If they can jump and get a grip on something, they will either pull themselves up or pull objects over and down. Items such as trash cans, tablecloths, laundry baskets, drink glasses, etc., are fair game. Ferrets are not destructive, but they do like to toss pillows off sofas and steal dirty socks and hide them under beds. Sometimes they think the sock on your foot is fair game so watch your toes.
