One night about a week ago I disconnected a length of the electric fence so that I could open the gate out of the pasture.  I left the wire on the ground while I hooked up the horse trailer.  It was still “hot” but it just put out a snap of a shock at one-second intervals.

Some cats decided to investigate the cyclic discharge on the ground, and I just happened to be looking in the right direction when one cat leaped five feet into the air and then cartwheeled across the fence like Puss In Boots from Shrek!
