A mountain of a mouse

I am a mountain of a mouse casting shadows ‘round the house seizing with stealth’s ease the baited traps delicious cheese for the shadow of my fangs gives the house cat nervous pangs and the thought of my long tail the house-frau’s heart to fail for the mastery of the light casting shadows in the night has them all seeing creatures with the most horrific features creeping ‘round the un-lit rooms darting past the swinging brooms stopping for a curtain call as shadow’s slowly fall the moon bids night adieu my shadow life is through no mountains in the house just the musings of a mouse
