Please help save our kitten!!

We are Britany and Ian . We are trying to raise money for our 10 month old kitten Rasengan. He was diagnosed on june 15th with feline infectious peritonitis or fip for short. It mostly affects cats 2 and under. The vet that diagnosed him gave us no options and no hope. I went onto Facebook and found an amazing group of people that have helped us get some not approved meds.  There is treatment but its expensive. He requires a shot everyday for 84 days or 12 weeks. We have gotten the first week covered and working on the second week. Its $240 for weekly vials. $5 for needles and $27 to overnight it. Which comes to about $3000 for the whole treatment. We are buying this weekly since his dose will need to be upped as he gains weight. Anything will help. We love our baby and we are trying to do anything we can to save him. Please help me save my baby!! He deserves to live a full life. Hes a fighter but he needs our help. Thank you.
