If you see activity like this then be aware you may have a squirrel trying to make entry to your loft space. A good sign is squirrels travelling up and down your fence line which could be them going to gather food supplies to store. Once they are in they can do all sorts of damage including gnawing cables. If you are hearing noises in the loft then it is certainly worth taking a look or get a professional company such as Pegasus Pest Solutions in to check it out.
