Well, my sweet Shadow got his 3 week post-radiation checkup today, and they say he's doing great! Such good news.
Nasty long drive in the heat for him and my poor, long-suffering DH (3 hours each way!), but at least we got good news. He's picked up a bit of the weight he lost during the course of treatment, but I still want to get a bit more weight on him. He was about 104 going in to this and he's only at 99 right now; and he really should be around 108.
He's being camera shy right now, little snot.
