It's such a cozy winter home if you're a mouse, and when you're hungry? Just snack on an electrical cord!
This sort of thing is exactly why we have regular maintenance on our machines. It just wouldn't do to electrocute ourselves or start some huge fire in our cozy home, eh? Mousie has an eviction notice, the machine is repaired and soon there will be repellant and/ or poison about. It's always something when you own a home.
Sorry for the poor quality of the photo. Our technician couldn't figure out how to send it to my email so I took a photo of his photo. Good enough.
