Who Stole The Cookie From The Cookie Jar?

One afternoon I reached into the cookie jar to retrieve a delicious homemade chocolate chip cookie.
To my surprise there were no cookies in the jar.
Instead the jar was filled with kibble.
Who took the cookies and replaced them with dog food?
It just didn’t make any sense. Over the next few weeks the mystery deepened.
I would wake up in the morning put my foot into my shoe and find it filled with — you guessed it — dog food.
We would open the cutlery drawer and find dog food covering the knives and forks.

The first clue to what was going on occured when my wife said
“We haven’t had any mice recently.”
A few days later, I had gotten up a bit earlier than usual and just as the dawn was breaking a blur of white streaked across the room. I screamed in fright.
There was a large crepuscular* animal in the house.
I had no idea what it was and had to look it up on wikipedia.
It was a stoat.
*Since this occured in the winter and it was pure white it could properly be called an ermine. In doing research I also learned the term crepuscular.
crepuscular is an adjective.
In zoology it means appearing or active in twilight.
Which explains why we never saw the beast (living in the north in the winter we went to bed before dusk and I was rarely up before dawn.)
