Help pay for Misty’s life saving medicine

Hello, me (Stephen Reese) and my girlfriend Rachel Tunney have a loving cat whose about 10 months old who was just diagnosed with FIP (Feline Infectious Peritonitis). This disease is 100% fatal without a certain medicine that isn’t FDA approved. After taking her to the vet we were told that even with antibiotics and steroids she only has a few more weeks. The only way to have a chance is with this medicine, but we cannot get it through any vet and must obtain it through third parties in which is very expensive ranging from $2,000-$5,000 depending on the type and severity. We have already paid a lot in vet bills just for the tests and diagnostics and cannot afford this. Our baby girl is a fighter and we want to do everything we can to give her the best odds at survival. Please help
