Since I've joined this site, not too long ago, I've seen several posts that are clearly made by people that do not know enough about electricity to do what they want to do safely.
The main difference between high current, low voltage arcs and low current high voltage is this. As you learned in welding class, with high current (the voltage doesn't really matter unless you are trying to pass a lot of current through a high resistance) you get a LOT of heat. Enough to melt metal. I've heard tales about people losing fingers when a metal wedding ring got between a high current low voltage buss and a ground buss. Any body part accidentally getting in contact with the arc will be badly damaged. These arcs also produce short wave ultra-violet light which damages eyes and why arc welders use welding masks.
High voltage, low current does not produce high temperatures, but this does not mean it is safe. High voltage produces enough of an electric field (pressure) to allow current to flow through a "high resistance" human or animal body, or body part. Actually it is the (dry) skin that has a fairly high resistance, the salt present inside animal bodies reduces this resistance dramatically. The current flow affects the nerve cells of that body without damaging them (enough current will cause damage of course). The effect can be a just a tingling sensation, that "bite" you get from a staic discharge, involuntary muscle spasms, to complete incapacitation (with a real nasty bite I hear). But as long as a low enough current is used, it won't permanently damage or kill you. If however, the right amount of current passes through the nerve cells that are responsible for making the heart beat, fibulation can occur, and without a defibulator handy, the person, or animal will probably die.

Sounds fine to me. I just wanted to see how much techno mumbo you were going to throw into my face before you asked me HOW "12V@600A will make a cat jump".
You already had an answer and refused to think about other posibilities. What bothers me about some of the "know it alls" in this forum is they quickly jump to one conclusion about something and flame on that conclusion not realizing there is more than one way to skin a cat!
BTW I am VERY guilty of this myself.
