I would like to say that An electric fence works by sending a signal to a specially designed collar, which will then issue a small static electrical discharge, similar to the kind you can get from walking along the carpet and touching a doorknob, but a little more painful. Without the collar, the "fence" does nothing.....
If you're referring to a metal fence that has an electrical wire along the top, or has electricity coursing through some part of it, it's possible that it could harm your cat, but the specifics are very dependent on how the fence is set up......
