Thank you all, I got so many responses! (All saying it's a sign
of insulinoma). We had the first girl's blood checked and it was
considered normal, but we'll do a recheck and I'll get the second
girl's taken too. The problem probably was that we didn't have it
checked when she was first pawing, but a few days later when they
could actually get her in.
