please help kittens with medical

These 7 week old babies desperately need help.  I rescued them when they were 4 weeks old.  I thought it would be easy to heal their eyes, but despite being seen by a vet,  prescription eye ointments and drops, antibiotics, etc., three of the four babies are not getting better.  The girl, (the calico) named Cherry has an abscess in her leg and unfortunately, her leg must be amputated.  One of the orange boys needs an eye removed.  Sodapop, one of the orange boys is the only one who is healthy.  The other three are still at the vet being treated for fevers and infections.  Tests are being run so the vet can understand better how to treat them.  This is all so expensive.  I hate asking for help, but I have to.  Please donate any amount you can.  Any little bit helps.  Thank you from the bottom of my heart for helping Sodapop, Dally, Ponyboy and Cherry (The Outsiders kittens)  A HUMONGOUS thank you goes to Wendy Painter Padilla who took over caring for these babies when I was too overwhelmed.  She has given them constant love and care and I could not be more grateful for all Wendy has done for these kittens.
