Thanks everyone. I am trying not to appear too stressed so that they'll settle down, but it's not easy.
sabau,
They are high and dry at a friend's house right now in Derry or Auburn, can't remember which one although they are pretty much the same if I remember correctly.
They have left a contact number with someone who will let them know when they can go back. My sister-in-law heard about the evacuation and tried to get home in time to get the cat but the roads were closed.
