Help Mochi get the medication he needs to beat FIP

Hello, I am Jennifer! As you may or may not know mochi is a new baby to our family. My daughter Aaliyah and I adopted him when he was 12weeks. Just before Halloween. He has brought so much love and joy to our family. This past week mochi stopped having zoomies or attacking our Shepard and been sleeping a lot. I took him to the Vets today I just knew something was off. Unfortunately I was correct. He's been diagnosed with Wet FIP which is feline infectious peritonitis, wet meaning he has fluid build up. I obviously was devastated and had to tell my children, because the vet said there was no cure. When we went to pick up Mochi from the vet she told me about a medication that hasn't been approved by the FDA as of yet but has helped 2 of her previous patients. I did some research joined a couple groups and the success rate is impressive. Financially we are unable to outright by this medication and need enough for 12 weeks of injections. Any little help you can do would make a huge difference. Thank you so much for your time.
