Oh poor squirrel. It is so sad to know they are in disadvantage part when it comes to electric fences, as they don't have that enough intellect to know they can get themselves in danger with these particular things. You must be a squirrel in your past life because it was easy for you to spot the "wrong" feeling that day. Kidding aside, it's is nice to know you are good at spotting pain in these animals. I hope they receive the medication they need but I really don't know your town's practices when it comes to squirrel getting hurt. It might be an argument but I say electric fences are not good, knowing we have far crossed the boundaries of where to build houses and ruin the habitat of them. Just my opinion.
