voltage enough to jump through paint will prolly manage to ruin all electircal systems ground to the car, including your ecu = car wont work anymore.

Ecu & airbags...
Intuitively yes, it does look dodgy Technically though, there's still only 12v across the batt terminals, even if one side is at 10000v. I guess the risk is if the spark jumps from the "wrong place" eg one of the ECU wires. (would need to have the hood open?) no? just theorising anyhow, not gonna go any further with this one obviously |

A way around the ground return problem (and the spark damaging the paint) would be to run a few parallel strips of aluminum foil over the roof/hood and electrify that, not the car. 230V would be perfectly adequate, considering it would have a nice chance of following a "front paw - body - rear paw" path.
If I get 'round to installing the motion sensitive sprinkler, I may as well just electrify that instead |

Poor cat...I did think about strips, but did not want to give you any ideas. If you do this, connect it through some large resistors so you don't kill anyone/thing. At least 100kΩ. |

How about a
Catwatch or Catguard? The catwatch couples an IR "presence detector" with high frequency sounds cats find annoying - looks like the catguard just stays on. No idea if these work, but it sounds like the right kind of deterrent - no damage done to the cat; they don't want to be near your car. Bob |

Perhaps a dog would work.
No, not geeky enough, how about a robot dog. or some of these babys: 12 GA. “Pepper Blast” A shot that will bring tears to your eyes. This 12 gauge shell will spread a blast of cayenne pepper directly from the barrel of your gun, disabling your target and allowing you to get away or take control of the situation. A blinding blast of Cayenne pepper can make that unwanted pest think twice. 2 3/4” round 3 Units Per Package $18.99 $9.99 On Sale! 25 Units Per Package $69.99 hope you're a decent shot.
