I have trained my ferrets to come running to the sound of a clicker, though I guess that's not really that impressive compared to that ferret who was on Animal Planet :-) I started out by making clicking noises with my tongue while giving treats, then making the clicking noises before giving the treat, then switching to the clicker during treat, then clicker before treat. I started out with the tongue-clicking first because it is a little quieter--I didn't want to scare the ferrets with the loud clicker until they were used to the concept. And it worked in a very short time. Seti and our departed Pan come/used to come running out of a sound sleep to the sound of the clicker. New ferret Ronan is already picking up on the concept. I haven't tried training them to do any other things with the clicker; after having had a deaf ferret for years, I was thrilled enough with the simple ability to call them :-) Regina Regina Harrison [log in to unmask] http://users.rcn.com/badriya/ blog: http://badriya-z.blogspot.com/ "Is that my business?
