I chased a mouse beneath the stair,
It went to ground, I knew not where;
For, so swiftly it ran, my sight
Could not follow it in its flight.
I coughed a hairball in the air,
It fell to earth, I knew not where;
For though my sight is sharp and true,
I saw not where that fur-bullet flew.
Some time afterward, quite by chance,
I spied them both in a single glance;
For the mouse in a corner lay dead,
A hairball lodged in his tiny head.
