My two males come running to the sound of a squeaky toy. They do not react negatively at all. In fact, I use it when I need them to come out of where they are hiding. They get a treat for responding sometimes. The females respond sometimes too, but seem less affected. In fact, when I got my first ferret many years ago, it was suggested that I train him to respond to this so I would not "lose" him. CEM and the clan [Posted in FML issue 4378]
