Hi, can you tell us a bit more please? how many cats etc. I've just replied to your other post and seen you're from Sheffield, it would be a good idea to modify your post and add this to the title.
Have you contacted rescues in your area?
http://www.catchat.org/adoption/yorkss.htmlIts a good idea to go through a rescue so that proper checks are done and the right homes found. If they are full then you could ask to go on their list or for 'Direct Homing' where the cats remain with you until the rescue finds them homes.
Best of luck.
