Oscar became sick on Tuesday, being very lethargic. By Wednesday, he threw up 6 times throughout the night while also developing a swollen nose. I took him to the vet, and they treated him for an allergic reaction and gave me meds to help him feel a bit better.

Today (Friday), he began to struggle to walk, breathe, and was shaking uncontrollably. The vets have no idea what's wrong with him and want to run several tests costing $1.9k, and then treatment on top of that. Anyone who knows me knows how much I love this boy and that he's my baby before anything. Any help will be so appreciated. I know this is awful timing for this with it being the holidays, but I couldn't imagine anything worse than not spending them with him.
