I am getting a electric fence energizer that can give a good shock, enough to make a raccoon not come back for a loong time. What would be a good voltage? We have a HUGE raccoon around, about the size of a small beagle. But at the same time we have cats, curious ones, as well as 2 small dogs and one larger one. I do not know much about electric fences, and would like to be as safe as possible! Anyone have suggestions?
