Also another thing ferrets love to play in is drier ducts, the shiny silver tubes that you can get at hardware stores in all different lenths. I would resort to getting something the ferret can play with more than something it will eat. They usually love balls or hard rubber dog toys, even some baby toys are safe, like the key rings with the big plastic keys. Ferrets love things they can hide. I use to have a ferret and the drier tube though was her absolute favorite thing to play in. Oh and pillow cases, they love to hide.
