Twas the night before the night before Christmas (southern hemisphere here) and all the through the house not a creature was stirring …until some bloody mouse decided to start making scampering and chewing noises in my bedroom - gah I’m already exhausted, stuffed up my day time vs night time meds and just when I’m getting to sleep some little rodent come to make my life a misery. I was really tempted to bring one of my cats in to deal with it but I know from experience thet they would be worse than the mouse.
You do know that when you’re sleeping, with your mouth hanging all open, the mouse will come up and look for food in it, right? Oh well, sleep tight! 
I thought they crawled under the covers looking for warm places.
That’s after their tummies are full from all the little bits of food in your mouth.
So they’re like the birdies that clean crocodile teeth?
