Finding some lovely little kitties a home

Hi all,
       I have four very cute kittens about five months old  that have been left by their mother a few mths ago, i have been looking after them for the past few months but been unable to find a loving home for them, they are very tame and would make lovely pets for someone, as i have a dog it is very difficult for me to keep any of them so i have been feeding them, but as it gets colder outside i fear that they really need a loving home.
    I have one all black,and two sweet tortise shell and one very playful ginger if anyone can give them a loving home can you let me know, i know all expats love animals so thought i might try to find them a home in the forum.
                                            Thankyou
