I thought someone was posting from one of those 'cat hoarding, breeding out of control' houses until I also saw there's also 10 daughters and 10 sons threads.
So hopefully not real kittens as its not always a happy back story (ex fosterer, the most we had to name in one go was 6, all girls who were given 'old lady' names after grandparents, great aunts etc, Florence, Nellie, Mavis etc).
