My cat is dying

Ponçik caught the wet fip virus in the first week of January. He's an 11 month old male cat. He caught this disease while struggling to survive on the street. This virus is a virulent virus. When we started his first treatment, antibiotics, appetizing syrups and serum were given. One day he was fine, but he was returning to his illness again. He could not toilet, did not eat, and slept all the time. Vets were saying your cat could die. I found out on the Internet that a cure for this disease is an injector drug called GS. But the drug was very expensive and was only a 5ml small bottle. He was supposed to use 84 doses. Since I am a student, I cannot afford the treatment costs. Don't let my cat die, I love him so much. Please support Ponçik in this process?
