Save Charlie: Urgent Help Needed for Sick Cat

Hello, my cat Charlie is 14 years old and has become terribly sick.

He was always a happy, talkative cat, but in the past two weeks, he has been lethargic and refusing to eat. Constant diarrhea and vomiting have followed, leading to him being very malnourished. I hospitalized him, but they were unable to figure out the core of the issue. Over time, the symptoms returned.

Personally, I feel it was due to a poor choice in hospital, as his health emergency happened late at night and my options were limited. I recently lost my job and currently struggling to find a replacement fast enough to save him. I'm completely out of money at this point, and I fear for his life. His vet is insisting I hospitalize him again, but I don't have the funds to get him admitted. This cat means the world to me, and I've run out of options to help him.

I ask for any help to possibly give him a few more years of life.

I'm basing my goal off what I was charged on his first visit and currently have 0 idea what the full cost will be. Any excess funds will be used for any further treatment.
