Did the earth move for you?
It did for us in Coventry two nights ago with an earthquake striking a couple of minutes before 1am. The bed shook, there was a bang and a loud rumbling, the cats jumped off the bed and there was the sound of a small herd of tiny elephants running downstairs at speed (Charlie and Missy are not light footed).
Dave woke with an exclamation of "Whuh?!!!!", to which I replied by calmly saying, "It's the cats."
What can I say, other than the normal cause of disturbances in the middle of the night are the cats. I woke as they fled the scene and naturally, my sleep befuddled brain put the noise, the movement and the rapidly departing cats together and came to the most natural conclusion.
I have apologised to the cats.
