Hi all,
Zoe's bile acid tests came back completely normal. That combined with her blood tests, x-ray, and ultrasound and he feels totally confident no shunt(s). The vet said he suspects IBD (or, less likely, an intestinal lymphoma). So she will be going in for a scope and biopsies next week.

She did drink a little water yesterday for the first time in 12 days. She hadn't had her Cerenia or morning meds, so I'm wondering if that is affecting her drinking.
I'm feeling hopeful, but worried we're on a merry-go-round of lack of conclusions. Hopefully not, and we'll know something next week.
