Candace, it was clear that what ever it was, was terminal, so I chose not to spend the money to have an ultrasound. He would have needed anesthesia and wasn't likely to survive that. It was likely cancer - multiple tumors, on liver, spleen etc, and they were bursting and bleeding. The other possibility was liver disease - the anemia - but with so much going on, the original vet thought multiple tumors more likely.

He lost SO much muscle from Saturday today, and was lethargic, extremely low blood pressure.
