The humans have a machine in the kitchen which they use to cook their food. It's called an oven. Why they feel the need to cook their food I do not know? Anyway, it hasn't been working very well lately so a man came in to fix it yesterday. When he pulled it out from the wall he found a little mouse nest and assumed their had been a mouse living there. Fortunately it was long gone.
The humans blame me of course because they think I brought it in from outside and let it escape. That may be the case but I am sure I didn't let it hang around for long enough to exploit the situation.
p.s. The heron is still there and doesn't even look like he's moved. He's just like a garden ornament, standing exceptionally still for long periods of time in the shallow bit of the pond. Not my idea of a good time - not moving with my feet in cold water - but each to their own I guess.
