I just bought one of those clear plastic Sheppard & Greene tubes for my kids. I was very surprised at what they came up with for "anti-skid" on either end... it amounts to 2 strips of metal which you're supposed to bend around the ends of the tube and crimp down, hard. Well, they don't crimp down neatly and I cut myself 3 times in the process of doing it!!! I wondered what they would do to ferrets' delicate feet. So I've taken them off again for the meantime. Why does Sheppard & Greene include something so dangerous in such a popular ferret toy?!?! Megan [Posted in FML issue 2509]
