Mouse Tale

There's a very kind lady at Number 5
Who welcomes small rodents and keeps them alive.
First they dine on peanut butter
Temptingly set below her rear gutter
In transparent traps that are humane
Smart pieds-à-terre protected from rain
Safe, too from predator's lethal claw
(That's Pat The Cat who lives next door).
Come the morn, Utopian mouse
Whose blissful constraint kept him out of the house
Is released by kind lady over the hedge
Who re-sets and replaces trap back on ledge.
She counts twenty-three she's caught, with delight
Not suspecting same mouse is returning each night.
