Hospitalization and Medication for two 2.5 month old cats

i have 2 cats that are having severe diarrhea now. and tested positive for feline coronavirus. and my male cat is in a critical condition. they are only 2.5 months old and I'm burning through my savings now for the hospitalization and medications. my female cat had been vomiting and having diarrhea since Sunday while the male was 2 days after. i took them both to my local public vet to get them dewormed but their health deteriorated quickly later that day. and just yesterday the male can wont eat nor drink water and even just sleep on his own poop. after bringing them to a private clinic they both got admitted and was put on IV. they are found out that they are under weight. the admission and test already cost me my saving and I'm now told that they need to be admitted for at least 3 days to get them monitored. I'm only a delivery rider earning 1000 a day for a 12 hour shift. and I'm burning 2000-3000 a day for them.
