Edit 7: This should hopefully be my final update here, as Bilbo got to come home from the vet today.
He is doing much better and is now only fighting a uti that we have antibiotics for.
We were also very pleasantly surprised to see that the bill was just under $600!
It's always nice when the total is less than you were quoted. ;v;
Edit 6: He has a GoFundMe now, if anyone is willing to donate or share his link I'd be immensely grateful.
Edit 5: Bilbo is staying at the vet for the next 72 hours and has gotten a catheter.
We'll have more updates and hopefully a total for cost in the morning.
Edit 4: Bilbo has gotten far worse, the treatment we paid $350 on Monday didn't help him the way it was supposed to and we were quoted $800 up front for emergency services today.
He's completely blocked up, he's lethargic, and vomiting and we're taking him in now.
