The Butcher's Cat

There once were three blind mice, who were not very nice.
They played mean jokes on the butcher's cat, who was never allowed to get them back.
For these three mice belonged to the butcher's wife, who could not stand the sight of strife.
So these three mice had lots of fun, and the butcher's cat was blamed for all the troubles they'd done.
But there came a day late in May, when the butcher's cat figured out how to make things go her way.
She gathered up thistles, and porcupine bristles.
The butcher's cat set up a trap, and waited patiently for it to snap.
Those three blind mice strolled past it twice.
Then thrice.
The trap sprang, the neighbor's dog howled in pain.
The neighbor's dog was in such a state, that no one noticed what it ate.
And the butcher's wife was the one who paid the price.
For no matter how hard she searched, she was unable to find her three blind mice.
