Vicky, thinking of you while you and your family are going through all
this

I can understand the panic with your FIL. I only have experience
with the hemoglobin with dogs, I had two that had Auto Immune Hemolytic
Anemia. I am glad he responded so well to treatment. Please keep us posted.
I am sure the service is going to be hard to witness.... keeping your family-
their family in my thoughts and prayers
