The second vet was much kinder, much more willing to work with us, and far more skilled. They've done an initial non-invasive procedure for him and are waiting to see if they need to get more aggressive, but for now, Kaiden is stable and will be there for the next couple of days. They let us see him before sending us on home...he looked like he was enjoying The Good Drugs but seemed happy for pets and the reassurance that we were still around. I'm feeling optimistic. Everyone who helped, you just have no idea the difference you've made today, but you are so appreciated beyond what I can express in words.
