Felix had a day staycation in CityU VMC on 28-29/6/21. After vomiting on Thursday, initially he appeared a bit sick, but slowly return to normal in the evening. On Friday (28/6), during a revisit, found his ALT to shot up to 333 - though the normal upper bound was 150, this was really nothing when compared with his previous records of 5,000-8,000. But for precautionary reasons, the vet suggested to have him under observation for a day. We agreed to it, because if we took him home and found him unwell, the situation could be pretty messy, for his vet's last day of service was that Saturday. This would also give the vet more time to do whatever checking she thinks necessary.
Ultrasound found the stent nicely in place. The biliary duct going up to the stent is a bit swollen at 0.6cm. Possibility that there could be some sludge. Hope antibiotics and Ursosan would work.
