The cat was in another room, so I don't know. It just came from nowhere, the glass started rattling then the house was shaking, then my chair which is on wheels started rolling across the floor. By that time it was pretty loud and scary. I've felt the odd tremor before, but nothing like this.
I guess they're pretty rare in the UK, Anji. I think on this occassion the epicentre was half way between Lulu and I!
