We have just had a visitor. Brought in by our cat Buffy.
Peter carefully trapped Buffy and the mouse in the washing basket. Buffy stayed in the washing basket. The mouse just strolled out through the gaps!
By that time our youngest heard the hue and cry and joined in. Poor little mouse ran all over the house, under the beds, under the wardrobe, in the walkin cupboard. Followed by Buffy, Peter, my youngest and me.
Eventually it lept in the box held by Peter, probably to escape my youngest who was bouncing around the walls by then. We released it back into the wild, hopefully not tooo traumatised.
