You should be afraid of them tree rats. They can mess up wiring real fast. It's like candy for them.
My brother has a 2006 chevy 2500. At its one-year-old mark one of those tree rats got under the hood and ate the main wiring bundle off the under-hood fuse box. Every wire coming in and out. Try finding an engine bay harness for a 1-year-old truck. Chevy was back ordered no idea on when it could be had. Took him 5 months to find a used harness. Needless to say, his infestation of tree rats has hit its all-time low for quite a few years now.
BTW they chewed out about 6" of wire out of that bundle. No way to pull enough slack to resolder them back together.
