Creepy thing

Of all the times for it to crawl out, it had to do so late at night, when the whole house was asleep. Only our demure cat lay in her cage; the more agressive one haven't returned. I was hoping to let the cats get it, like they always do.

But there was only me...and that creepy thing. So it was my decision - Leave it be? Or make the kill?

PS. Thank goodness it's a large one (yes, I mean it), and not tiny enough to hide in obscure places.
