Urgent Meds Needed, Please Help

We rescued Nirvana in December of 2024. We found out soon after he has FHV-1 and a weakened immune system. He's a total mom to our other cat, Willow. Nirvana loves to run around the house, chase his jingle ball, and feast on tuna and salmon treats. Nirvana has his own favorite shows, including H2O: Just Add Water, and loves when me or my partner play violin or guitar for him. He's the type that follows us around the house, purring and accompanying us throughout the day. He's always waiting by the door when we get home. Nirvana recently came down with an inexplicably high fever, and was hospitalized for a week in critical condition. After finally getting him to a specialist, we found out he has FIP. In order to keep him alive, and afford the new medicine, we need help. Nirvana can't survive without the medicine he needs, and with FIP, the newly developed medicine has a 90% success rate for survival. If he doesn't receive these meds, it could be fatal in a matter of weeks. Even if it's small, anything helps us and we greatly appreciate it. We want to keep our baby alive, healthy, and safe.
