Product review (1 stars): Danger Contains Carcinogens! Not safe for human or ferret handling.
I bought this for my ferret, but neither I nor she will be handling it. Ferrets are already so prone to cancer and this duct contains carcinogens.  It was not stated in the description, but was stated on the box that this tunnel is made of carcinogenic materials.

Sent to return as soon as I read the packaging.
