Rhys vet bills

This is my boy Rhys. I adopted him from a rescue on Sunday. He has been nonstop puking since Monday night. He has yet to eat or defecate. After taking him to the vet and getting blood work, X-rays, and some shots, it appears there may be a foreign body in him. I was told he might've gotten into some fiber fill at the foster home, which I was not aware of. Now, on the way to the emergency vet to get an ultrasound. He was hospitalized for the night as well. The ultrasound came back that he has issues with his intestines and pancreatitis. He also has a kidney infection and possible kidney disease. The rescue won't help pay, and I want to help this sweet boy feel better. I didn't adopt a cat expecting to have these expenses; I just wanted a friend, but he deserves a home. I understand the holidays are coming up, but anything at all will help. I'm a night shift working student, so these were very unexpected expenses at 19. I appreciate anything, and so does Rhys. Thank you so much.
