Help Raja Fight FIP: Support His Treatment

My sweet baby boy, raja, got infected with FIP (Feline infectious peritonitis), it is a very rare, painful and fatal viral infection with a 96% mortality rate when left untreated. He suffers everyday he does not get treatment. Cats typically only live within 3 weeks to a couple months if left untreated. There is no cure, but with treatment there is an 80% chance of recovery. He's a very sweet boy and we love him very much. We're doing everything we can for him but this treatment is very expensive and we have to treat him anywhere from 12 weeks to longer based on how he reacts to the medication and its hundreds of dollars monthly. please help our baby, anything helps. :(
