What a beautiful girl! I'm so sorry for your loss. I just had to put my magnificent Little Bear (http://catoftheday.com/archive/2010/February/06.html) to sleep on March 9; he also had cancer (squamous cell carcinoma), original site was in his cheek, radiation and other non-chemo meds seemed to stabilize the tumor, but it spread to his sinus/nasal cavity). My heart goes out to you, as I know all too well what you are going through.
