The neighbors were counting their cats! I could not imagine anything climbing that high on the pole to get to safety. But, another neighbor said a raccoon got up on the pole by his house years ago, went to grab the wire with his little hands, got zapped which tightened his grip, and he was hanging from the wire until the electric company came to get his dead body down. Learned something else from that neighbor, who worked with electricity his whole life. If you ever have to check an electric fence wire with your hand, do it with the back of your hand. That way, if it zaps you, you won't grab onto it, which is what will happen with an electric shock, your hand clenches. So, pass it on! Not that anyone will check and electric fence wire with their hand ... at least I sure won't, not on purpose anyhow. LOL
