Help with medicine to save his life

Hello my name is Viola. I live in Missouri. I found out my fur baby was diagnosed with FIP on March 19th I had enough to buy him 5 bottles of his medicine. He has to have 1 shot a day for 82 days and he will be cured. The medicine is very expensive it’s 85.00 a bottle. Bob is 1 years old he is a f5 Savannah. I’ve spent 1400 on vet pill and his first few shots to get him started. Im worried about not having the money to continue his treatment and do not want to see him pass away. Please help. Or even share to ur friends. Thank you!!!
