I just talked with the vet. The good news is that Monarch is resting and will be transfered to the emergency hospital in the next hour. The concerning news it that the Vet told me that Monarch had an enormous shunt. The largest one that she has ever seen.
Monarch's liver is really small since very little blood was actually going through the liver. In a couple of days the shunt will be closed and the liver will have to start working a lot more than it ever has.
