Help Fix My Feline Friend

Bones and I just left the Animal Vision Center, and I received the devastating news that she has a tumor behind her left eye. She has already lost vision and they are concerned that it may have spread to other parts of her body. The suggestion is to have her eye removed, which breaks my fucking heart, but once she recovered from the surgery she would most likely have several more years left in her, and be pain-free. The catch is that she also needs a chest x-ray and blood work to make sure that it hasn't spread to her chest/lungs before they could put her under anesthesia. The running total of all of the testing/surgery/appointments is roughly around $3,500.

I picked Bones out from her litter when she was just 3 weeks old, and immediately went back to get her and bring her to her new home as soon as she was 7 weeks old. She has been with me close to half of my life, and she still has spark left in her. She deserves the world. I usually always figure it out, but this time I feel like I'm in over my head, and we could use some help. I really appreciate you taking the time to even read this, and even a share or two would be amazing. Thanks in advance.
