Please help save my kitty!

Last night I had to bring my sweet buddy to the emergency animal hospital. They're still running tests and trying to figure out exactly what is wrong, but his intestines are inflamed and he can't regulate his glucose on his own. He isn't stable enough to be home and has to stay with constant medical attention. The expenses for the tests alone are outrageous on top of him having to be inpatient. I don't have the money to pay the full bill, and i would feel so awful if I end up having to make the decision of giving him up because of expenses, he deserves the chance to stay alive. I hate to ask and I wouldn't have made this if it wasn't the last resort, but I have no choice. Any amount is super helpful and so appreciated, even if it's you just sharing the link to any of your social media accounts.
Thank you so much for all of your support and concern.
