Oh, what wonderful news!!!!!!! I am so, so relieved for you. My heartdog, the Lab of my life, passed from liver cancer, and I was so hoping that Peterson's biopsy would come back negative. Liver disease, however, is tough on a kitty!! So try not to despair over his appearance right now. The important thing is that you know now what it is, and he can be treated. The weight will come back slowly. Just take it a day at a time. Bless you precious Peterson. Hearing the good news has made my Easter extra special. Love and hugs to you dear boy, from Sandra, Mr. B and Oliver
