Surgery and treatment bills for Tom and vaccination package for 46 cats

Tom is my senior cat of 9++ years old. Last year he was diagnosed with a cancer called "fibrosarcoma", in which a huge lump will reappear on the same spot and need to be surgically removed. Until now, he had undergone 4 times surgery. The vet suggested to proceed with a few sessions of chemotherapy and a set of herbal medication for him for at least 3 months. Please help him to fight this battle, because I can't bear the expensive fee alone. Even though the vet said the cancer is benign, however I don't want him to undergo 3-4 times surgery in a year.

Meanwhile, I am also a cat rescuer and currently I have 46 cats under my care. Most of them are fully vaccinated and neutered. Since 8 of them are currently struggling with chronic flu and I'd spent a lot for them and a few others for other medical requirements these couple of months, therefore I'm very tight in budget to bring the others for their yearly vaccination package (vaccine + deworming + deflea).

I hope I will receive the support in order to make sure the cats are in healthy condition before I can open for adoption for some of them and are able to rescue other cats who are in need. Please help me to help them!
