Oh what a scary night...already the storm made me frightened, but I would have been really shocked when my cats would have sneaked out like Luna and Lily...that must have been terrible, Kirsten!

Maybe your Lily girl has learned to open the door, my sister's cat has learned it too and you know, once a cat is familiar with a trick, they'll never forget...I would not only close the door, but always shut it with the key, just to be sure Lily won't be successful again...
