I'm not convinced you actually have cats. I have seen no evidence of cats in your house (except for the occasional pair of glowing eyes underneath the furniture). I think you're renting used cat litter and cat toys from a neighbor to make people *think* you have cats.

(But if you did have cats, I'm sure they would be adorable ones.)

The quake in SF was mostly noticeable as a slight rolling and mild vibration in the windows. Still the strongest quake I've felt up north.
