i have a 100,000 volt stun gun (tasers are only 50,000). zapped myself and it did not do crap. i felt it, for sure, it even left red burn spots, but it did not bring me down or cause loss of use of the arm or leg zapped. so i changed the battery just in case. i am very disappointed. maybe weight has something to do with it (i am 250). i am thinking of trying it on the cat?
