The other evening, Nanki-Poo was playing vigorously, batting a toy around
and having a great time.  When I went toward him to see what he was playing
with, he picked the toy up, looked at me defiantly, and walked away from me.
I could see then that it was a rather plump mouse.  There was no way I was
going to get it away from him, so I left him to it.

I went to bed, leaving him with his "toy", and knowing I'd have a little
corpse to dispose of in the morning.  I hoped he'd just leave it whole, as
he does when he kills a rat.

When I got up, I found some entrails in the hallway.  On my beige carpet.

I never found anything more.  It's been two days now, and I still haven't
found any more bits of mouse anywhere.  Apparently he ate it, but surely he
didn't eat the tail!  So what did he do with it?
