Hi Dave, A couple years ago i had a surrender ferret that came in to the shelter, i had a couple tong toys and he just loved them a couple weeks later when i found Pippin he was in his cage and he was throwing up his own bowls and when he did poop it was like a shoe string comming out of him, i took him to the vets and there from x rays he had a big blockage they did emer surgey on him, i almost lost him but he pulled thru the surgey, i got home then evening and found the tong toys in his hidy hole in the qurateen room he had ate the top of the rubber off plus been chewong in it, i threw them all out and im scared of it happeneing it again to one of my kids so to me they are dangres Susan- Director Arkansas Ferret Rescue for Hospice and Sp Needs Ferrets [Posted in FML 6650]
