Helga, you brought up a great point. We *responsible* ferret owners will know not to leave these pretty collars on our ferret all the time. But, someone unaware of the ferrets suicidal nature might not take the warning seriously. Not long ago we had 4 ferrets in a playpen setting at PetCo for education. A new volunteer brought a wad of crinkly plastic for the ferrets to play with. It was such good fun, until we realized we were sending the message that ferrets should have something to play with, stash, chew, and possibly swallow that could be deadly. The wonderful toy was tossed, even though we knew to be careful and supervise. Ardith [Posted in FML 5579]
