Thanks for the encouragement. It's Sunday afternoon: we just got back from the vet, she seems perky and her comb is nice and flush. She went back up to 4.1 pounds but regurgitated her afternoon feeding. We got the blood test results and she did have high levels of lead. She is at 65 and she should be at 10. Pellets haven't moved. They are going to give it a few more days.
