Twas Not Me

When I went into the utility room this morning to feed my cats, I found this on the floor.  The gentleman who delivered my King Soopers order put the sack in the utility room; but, I neglected to stow it in a safe place.  If cats could talk, I'm sure neither would own up to said mischief.  I, however, think I know who sunk his shark-sharp teeth into the kitty kibbles.
