Urgent help for Chonk’s medical bills

Hello, today (2/26) I took Chonk to the vet for decreased appetite and energy and had some blood testing done for him. What came back felt like a train hit me. The vet let me know that he potentially has cancer, lymphoma, and I want to put up a fight with my orange boy against this. To even get the testing to confirm or deny this being lymphoma, it is estimated to cost $721.78. The reason my goal is at 5K is for further treatments and other investigative procedures. I will attach a photo of the vet’s estimate as well as proof, with him in the background. 

Chonk is a very kind, funny, ornery, and cuddly boy. He has such a strong personality that everybody loves. He loves to go outside on his harness and explore new places. Chonk is kind to everyone he comes across and he quickly becomes one of their favorite cats. Chonk is a pure, happy, orange tabby boy who is a bit of a menace. I had to put baby locks on my cabinets and hide his treats from him. He solves every puzzle I give him and loves to play with little plastic balls.
Chonk is a huge part of me, and I would do anything and everything for him. He has been with me through the toughest times in my life and I need to be there for him during his.

PLEASE share. Please get the word spread. I feel so powerless and just want him to be happy and healthy.

Edit: The photo of the vet estimate is not showing up in the text of this post. I did make a TikTok regarding the situation that does include the image.
