Okay, the shock is wearing off. Bobcat and I talked and we're making an appointment to get a second opinion. I love my sister's vet. He is very good and very caring. Waiting to hear back from his office to see when we can get Halo in for x-rays and bloodwork. I did some research on the internet late last night and found a few websites. One said that 50% of liver tumors are not malignant. They also recommended a biopsy. I'll keep you all posted.

Thank you for continued support and concern.
