I am so sorry for the loss of Piccolo. I remember the day I lost my Genevieve at the age of only 12: April 15, 2000. She was diagnosed with intestinal cancer, and with chemo (which cats tolerate better than humans) she was able to live comfortably for four months before her quality of life deteriorated. It was terrible to have to make that awful decision. I sympathize very sincerely with you for the loss of your beautiful boy.
