Cat and Toy Mouse.

Nancy has always enjoyed pushing small things off tables, and it's taken me a while to realise that that would probably mean she would enjoy pushing things down the stairs.

So now I leave one of the foil mice halfway up the staircase, and it will just sit there until Nancy feels like playing with it.

Of course, being Nancy, she will not do this when I've got my camera ready to capture the magic.  So you'll have to believe me when I say it is adorable, instead here is a photo of her staring at the mouse, and another of her giving the thing a thorough nomming.
