I was concerned about the amount of charge used for the 'correction', the info says it's about the strength of a static charge, so it should be safe for fuzzies. the newer models may indeed be safe, but try it out against your neck just to be sure. several years i tried one before i'd let my dog wear it and the thing HURT!!! and that was on a human-size neck. admittedly, dogs have a lot of fur to dissapate some of the charge, but ferts don't. so check it on the most tender part of your neck. -- rainey [Posted in FML issue 1885]
