19 Ringworm cats and kittens

Hi everyone, I am setting up a fundraiser for 19 foster cats and kittens that have ringworm. We started out with 3 kittens with ringworm and now have 19. This is a very verilent strain and the first 3 now have it again.  Several have been to the vet and meds are expensive. We also feel we need to run a PCR test on several to make sure they are ringworm free once treated. We will be spending at least $200 per cat so $2500 won’t cover all of their treatment but will definitely help. We have two very dedicated volunteers taking care all 19. 
We could really use your help in treating these babies.  Thanks so much for your help.
