I personally dont like children very much, and if they were jumping in my garden over my fence i wouldnt enjoy it, but theres no way i would start putting up electricfied fences to control the "pests".
These animals belong to someone, just as your children belong to you. How would you like it if someone as malicious as yourself was purposefully inflicting harm on them?
polite request to the sane people of this forum:
please could you stop giving this nutter ideas
. thanks.
Cats despise water more than anything else, if you rig up somesort of spray to defend your barriers, then that would be an infinately better way.
Maybe you go rig up a sprinkler that is somehow controlled by an infrared detector, such as the ones used on security lights. That would definately make them think twice about deficating in your garden.
