She now comes in through the catflap late at night and miaows in a particular way for attention. The sound is unmistakable as she has a mouth full of mouse. She then deposits the mouse in the hall in front of my bedroom door (directly in line with my pillows, so I can't miss it), bats it about a bit, looks in my direction as if to say "Deal with it!" and promptly stalks off.
When I attempt to retrieve the unfortunate mouse, she suddenly comes back to watch. Sometimes she tries to swat it from my hand. I get the distinct impression I'm being Ofsteded by my own cat...
She appears to have discovered a regular supply - yesterday she brought me three. I have visions of seagulls lurking in dark alleys: "Pssst... you wanna score some mouse?"
