Hee hee - CatsinDenver - they should be there just long enough to store up all sorts of complaints when you come to fetch them for the journey to their new home. And you, of course, will know not to believe one word, one "but meeoowwwwmmmmmiee!" of it!

What a lovely gift, knowing your 6 have a safe haven for a time - even if they don't quite believe it's safe to come out yet!
