Goose's FIP treatment

Hi, my name is Kitty and I'm raising money for my sweet cat, Goose. I just lost my precious 5-month old kitten to FIP last week and now Goose has FIP too. Most cats catch coronavirus at some point in their life and show few symptoms. A small percentage of cases mutate inside the individual's body into feline infectious peritonitis (FIP) and the rate of mutation has been increasing causing more cats to be infected. As of right now, Goose will not eat and spends most of his time hiding. He has already lost 3 lbs. FIP has been fatal for decades but in the past few years, a successful treatment has been developed. Unfortunately, this treatment is extremely expensive. The vials of the drug alone cost will cost $1200 at the very least. The price is expected to increase as he gains weight back. I will also have to take him in for bloodwork on days 30, 60, & 80 of treatment and there are several prescriptions he will need as well. I will need to purchase all of the supplies myself such as needles, syringes, supplements, etc. There are very few foods that he will eat given his near-nonexistent appetite caused by the FIP and these foods are costly. I usually only buy these as treats due to the price. It all adds up quickly and is definitely out of my price range, but I won't give up. I appreciate any donations immensely.
