This can get out of hand. As a kid I was given a little mouse and Dad built it a cage to live in. A big sucker with all kinds of room to run about when I was at school. Charlie the mouse was very tame would crawl down into my bra and peak out the top of my shirts and sit on my shoulder and squeak at me.
One day I came home from school to find Charlie had given birth to 8 baby's . You can guess the rest, I came home one day to be told Dad had gotten religious streak and sent them home to the Lord. Baptism was his way of going.
By then we had a couple dozen mice in a cage and that one mouse of mine had built as their Empire. Floods happen, mark one down to climate change.
