I'll miss you, Barnabus
Edit: Thank you to everyone who has expressed concern. Being the good Catholic I am, I'm absolutely guilt-ridden. Barney hadn't been able to keep anything down, but I wasn't too worried about it. Then I noticed that he'd stopped eating. Then stopped drinking. I took him into the vet on Monday and she suggested keeping him overnight to get some fluids in him, but I balked at the price. So she gave him some subcutaneous fluids and took blood for tests and said she'd call the next day when the bloodwork was back.
So Tuesday morning comes around and Barney's sitting on my bathroom counter. I gave him a little extra love (I'm so thankful for that) and told him we'd get him feeling better soon. Then I went to work, went to vote, and came home and found him. I'm not sure when he died that day, but....
Anyway, thanks everyone. I miss him.
