Catquakes

Where I work, in my sewing room, is under a loft bed. Last Monday I thought we were having a lot of earthquakes. Every hour or so the desk would wobble, and my computer screens would shake a bit too. I kept checking the NZ geo website to see if there were any quakes registered, there were none. It took me till Wednesday to figure out it was the cat, on the top of the loft bed, scratching. Not sure if this can be classed as either a senior moment, a blonde moment, or a stressed out Mummy moment. Think it is probably the latter.
