Emergency Medical Bills for Charlie

My 5 month old Siamese kitty Charlie had some unexpected complications following her spaying. She became very lethargic a couple days after the operation, had a fever of over 106 (102 is normal cat temp), and was not eating or drinking anything for a couple days. I brought her to the animal emergency room and is currently being held overnight, possibly 2 nights, to monitor that she is getting her fluids, antibiotics, and to ensure the fever keeps going down. This has landed me a very unexpected $5000 medical bill I am struggling to figure out how to pay. I would normally never do this, but I am out of options. Any help big or small would mean so much to me and Charlie. Much love, and happy holidays❤️
