Good news, Nickodemus, as my husband has named him, is seemingly going to pull through! He has been much more active these past few days. He has been climbing down off his perch to get his own water, and wandering around the room, exploring. He even has his own favorite spots to bask and sleep now. He has even visibly gained weight. He's still quite thin, but I can no longer see the outline of every rib bone. It is amazing to me how much of a change I have seen in just a few short weeks. He still has a ways to go, but he'll be very spoiled every step of the way.
