sorry to hear about this, Nem, I feel for you - we had a 'sneak in' theft last year & the feeling of having been violated still hasn't gone away.
Thing is, we do have an alarm, but as we were in the house at the time, it wasn't on - and stupidly we left the back door unlocked .....
So my advice is to make sure all doors are locked, even if you are in the house - the toe-rag was in and out with my wifes handbag/phone/cards/keys in literally seconds.
