Too bad you can no longer get those high-powered solid state lasers from Russia. Now you are forced to build your own CO2 cutting lasers. A little fire on the butt would make an excellent deterrent. Enough "juice" and you can pre-roast your dinner! Just make sure you are wearing protective goggles first.

A nice high-powered Ruby-YAG (excuse me its been a while if I got it wrong) would be fun in likely plucking the critter at the same time as roasting it. That may not be entirely ethical though...
