A mouse in the house

My cat Cleo managed to sneak a mouse into the house last night.  She brings in lizards, too.  All so her little sister PB has something to play with.  PB isn't allowed outside since she only has the use of three of her legs.  At any rate, there was this poor little field mouse dashing hither, thither and yon with PB chasing it.  It finally ended up in the pantry, which the cats can't get into.  Although I opened the doors I couldn't see it for all the stuff stuffed on the floor.
If the mouse moved around during the night I didn't hear it. 'Course my hearing aids were out so....  But this morning I awoke to PB making a racket in my bathroom.  She was desperately trying to get behind the door which I keep open via a water filled jug and old iron.  I knew there was something behind there so got my handy-dandy flashlight (just in case I had to smash something).  And there it was....a tiny field mouse....trembling and almost paralyzed with fear.  So much so that I was able to reach down and take it in my hand.  I think PB thought I was going to give it to her.  No such luck, cat.  Instead I went downstairs, opened the front door, went out on the porch and let the mouse do a high dive into the grass below.  Not to worry.  When Cleo wanted out I went out to check and there was no sign of mouse.
This is not the first time Cleo has managed to sneak a mouse into the house.  I try to check every time I let her in but sometimes, well..........
Needless to say I had a talk with Cleo.  She pretty much just sat there and stared at me.  Her expression was such that I knew she was thinking I'm an idiot to believe she won't get another one past me.
Such is life in the country.  Wouldn't change it for the world.  Y'all have an interesting day.
