Kittens with FIP in need of medicine for the cure

Hello. My name is Carrah Sandage. I have been rescuing cats and kittens and also dogs for over 15 years. I rescued a litter of the sweetest kittens who got sick with a severe disease called Feline Infectious Peritonitis (FIP). There is a cure now and the kittens are going through it but it is very expensive, about $1200 per kitten for the medicine. There are 3 kittens, Raven, Dove and Jay that have it but I could only post one photo. They have a chance of a long life after the treatment. So far they are doing well. Please help me help them.
