Thanks all...I do trust her. I'm just paranoid about it...I called a friend of the family, a Vet up in Vermont and relayed the symptoms, blood results, etc. and he said he would suggest following the same course of action, so I feel more assured now.
He mentioned to request a bile acid test....so I think I'll do that, and he said while a shunt is possible, it's very rare, but also easily fixable if that is the problem, it just has to be fixed asap.
I'll just keep saying prayers and hoping it is nothing....he's such a little angel....and so so sensitive....
