My ferrets (and dog) love Good Boy chocolate drops. It is a synthetic chocolate that I found in a pet store and Foster and Smith catalog in the dog treats section. Whenever the ferrets hear the box being opened, they come running! Tiger will find the box anywhere and climb anything to get at it, so we have to be careful to put it somewhere he definately can't get to it. I found that these work as great training aids since they love them so much! As with all treats, only in moderation. Tiger found out what it was like to have a sore tummy from overindulging!!!
