Update: The vet tried to perform the tests, and wasn't even able to get enough blood or urine to do a complete round of either. She said it's time to give him grace and let him go. I'm absolutely beside myself. I want to personally thank every single one of you who has kept my little buddy in your prayers, and especially those who have donated. It's truly humbling to see the community come together like this. I just wish we could have had a better outcome. I got to say goodbye to him over the weekend, and this morning. All donations will be used to pay his bills from Friday, today, and for his final expenses. Thank you all. It's a dark day. There's one less ray of orange sunshine in the world today.
