The patient was presented for vomiting 3-4 days prior. Was recently gagging, not urinating often despite normal drinking. The patient had a decreased appetite or was not eating at all and having innappropriate defecation in the house. Blood chemistry showed liver enzyme elevation and low BUN.

Recheck blood chemistry still showed persistently elevated liver enzyme activities, hypocholesterolemia, low urea and creatinine concentrations. The neutrophilia and monocytosis were still present on the CBC, however thrombocytopenia was also present. Serum bile acids were severely elevated, both pre and post-prandial.
