Saving Kit Kat

Kit Kat was a foster kitten that I adopted 4 years ago.  She started sneezing and had runny eyes a few weeks ago, so the vet put her on antibiotics for an upper respiratory infection.  The meds didn't seems to be working and her eye was starting to look odd so I had them run some blood work on her. Based on the results of her blood work, she was  diagnosed with FIP which use to be a fatal, incurable disease for cats. I've lost 3 of my cats to FIP over the past several years because there was no treatment for it.  They now have a new medication that cures FIP but it's very expensive. Its called Mutian. I hate asking for help but there are so many people treating their cats with this new medicine and the cats are showing improvement immediately & are completely cured by the end of their treatment.  I can't let her die knowing there is a cure now. I just need some help to get her started on the meds while I find another job to pay for her full treatment. She is a maine coon mix and has the sweetest,  funniest, sassiest personality. We love her to pieces and want her to beat this & live for many more years. Please help or share this. Anything is appreciated. Thank you so much.
