Finally! I bought 4 bricks to seal up the hole in the wall. Momokuai is wondering how she can move those bricks away. That area of the house has suddenly lost its charm to them and when I put them outside they will paste their noses on the glass door hoping against hope that I will let them inside. I know, they would love to come inside and crawl into the bellies of my couch or fridge. Or get more plaster off my wall.
