It is easy to get the cat to set off an arc. The cat would probably walk on the same parts of the car and you know this because it leaves the paw tracks. You can setup a boobie trap pretty easy. Cat trips a switch, voltage turns on and a arc sparks next to the switch it tripped. Ever sparked wires together near something not expecting it? JUMP! It would be all the better at night as the sparks would be brighter.
You can also set a fire cracker with its fuse in between the spark and light the fire cracker and set it off. That will scare off just about anything and may make it not return. Might worry the neighbors though.
Only reason I know this is because I have done it. Passed the spare time in welding class back in high school.

Ok jaydee, one last post just to clear a few things up. I'm not trying to piss anybody off. I'm just trying to make sure that people in this forum that are thinking about using electricity, do so in a manor that will not get anybody or anything accidentally hurt or killed. 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 resitance" 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.
