Update: I talked to my mother finally. She said that my Step-dad, Steve, took Chloe to a different vet and was told that unless they could pay around $600+ for 3 different tests, to figure out what is wrong, then she only had about 3 months, at the most, to live. And that's not counting all the painful pokes and pricks she would have to endure...She was in pain and was not getting better from the medicine after all. They decided to help her to the bridge this morning and Steve was taking her to the place where my Jewels (RIP 9/16/01) and my mother's other kitty, Tigger (RIP 2006), was cremated to have her cremated as well. I am trying to get around to everyone to leave thank you's for your kind words. However, the beans keep unplugging the laptop and hindering the process. I am making my mother a scrapbook of the boys and her cats for Christmas and am thinking of including a page with all of your comments in it. It would definately take her by surprise and make her smile.

My mother sent me a text message saying that Chloe had crossed the bridge. I do not have any details, as I am waiting on her to call me around lunchtime, which is any moment now.
She was doing much, much better last time I talked to her. But, we didn't make it to church yesterday for me to ask my mother about her. I know Sandy and Snowy (Chloe's twin) are probably sad and looking for her.
I will have the full story as soon as my mother calls.
