Three senior cats left alone in apartment

We raised $1725 for these three boys and the estate donated $1000. Total bill came to $5116 so we still need another $2400. When we took in these three cats in we had no idea all three cats would need emergency dentals. Grayson was so bad he had sores in his mouth. All three had almost all of their teeth removed. Blackie had an abscess under his chin so has needed antibiotics. Good news is with time these kitties should be able to forget the last 3 years where they were basically abandoned in an apartment alone being fed sparingly.
