Medical Help for Skittles

Skittles was a stray cat that I adopted because she was starving to death and pregnant when she came to me. When I first found this cat, she was freezing in the winter and came to me out of desperation just to sit by the fire (Skittles is named Skittles because of how incredibly skittish she is). She was far too emaciated to carry her kittens anymore, so she ended up running away to miscarry. After a week of searching, calling, listening, and staying up until 3 am to find her, I finally heard her meowing in the crawlspace, which I had already checked several times. She was on the brink of death, barely able to stand, and must've been screaming to get me to hear her. I had to feed her carefully and by hand because she couldn't even lift her head to eat or drink. She is the most grateful, respectful, sweetest cat I have ever met in my life. You can see in her eyes how grateful and content she is. So you might imagine how much it breaks my heart right now that I can't afford treatment for her. Recently, she started with a drooling problem. It happened relatively quickly, and evolved into her bleeding from one of her teeth. She was bleeding so badly that she became weak and lethargic and started to develop a fever. It was so bad that every time I wiped it away, it was just pouring out of her mouth. So, in the morning, I took her straight to the vet. When i woke up, there were blood stains all over my sheets (she sleeps on my bed). He told me one of her small front teeth had been fractured, likely from jumping down from something high. He gave her an antibiotic shot and something to bring the fever down, and recommended that I return to have some of her front teeth removed. If I didn't, he said, the infection would just keep returning. I was barely able to afford the 98$ visit that day, despite how cheap that really is. Even 10$ is a lot to me right now, it pains me to say. The vet told me for her final treatment plan, I would only need about 270-300$. This would include dental surgery, another antibiotic shot, special food for her while she recovers, and some important testing that needs to be done to make sure there is not an underlying cause for her teeth breaking so easily, such as feline leukemia.  Please help me save my cat! I love her to death and her and I have battled so hard to keep her alive, happy and healthy!
