So I lost my keys, and no-one's at home but Otis fluffy bunny.  I
shout through the letter box - "Otis, you're a very clever cat and if
you can fetch the spare set of keys and jump up and pass them through
the letter box I'll give you a treat".  He comes up to the letter box
- looks up at me with those big green eyes and says:  "Me - How?"
