Thanks for the feedback it is kind of what I expected. I had been cutting wood all day at -6 and the cold had probably got to my head.
We live in a rural place with a large wooded, orchard & dry stone walled garden so I imagine mice have lived there for ever. They can see this as a xmas present to stop as many dying in this weather, hopefully won't lead to a population explosion!
In six years we have had one mouse in the kitchen and one in the loft, both caught in a humane trap (see always been soft).
I once had a friend who put a snap trap in the void under his floor, he heard it snap and then a few seconds later he could hear it dragging along under the floor for about 5 minutes. That was a funny story.
