Marty,
As promised, here are some updated pics of Grace. She weighs in at 504.5 grams today, and is doing great. I mentioned that she had missed some meals, and I thought she may be slowing down, but she proved me wrong and ate this week.
In the pic of her scar, I put my lens cover from the camera for size comparison, and it is 2" in diameter. The scar is the browenish line in the center of her belly. It appears to be about 4" long.
