A electric horse fence is a better option. Will zing you but isn’t lethal and also has an intermittent current. Specifically designed to be touched by living things without harm. But stay away from cattle fencing, that can kill someone with a heart condition.

I used these all the time as a kid. I haven’t seen one in a few years though.

The fact that you have to explain this is making me feel very god damned old right now.
