Katie, I'm so very sorry you are going through this and all because you just can't turn your back on a cat in need. I can't help in any practical way since I have a house full of fosters (3 adults and 14 kittens) as well as my own.

Where did you post on Best Friends? I didn't see anything that looked like it came from you on the animals in need forums. Have you gone to your state's community on the Best Friends site? You can contact the community manager and they can post a story for you. That will be your best bet at this point. Best Friends is rather overwhelmed at present because they've taken on two large sanctuaries that had failed and are having a hard time getting the hundreds of cats in them adopted. There are people on the B.F. network who should be able to help you, people who have contacts and may be able to persuade sanctuaries to shoe-horn in one more cat.
