Help Piper fight with FIP

Hello everyone. My 5 month cat Piper ( Pepper ) has been diagnosed with FIP ( Feline infectious peritonitis) wich is a very bad disease and with low rate of survival. The treatment costs 900 to 1000 dollars wich is a bit much for us and we would like to ask for your help to save our little boy. We started the treatment today. We got the first bottle wich will be enough for 5 days and one bottle is 60$
