Is this healthy?

Star is a true survivor…..how long can she live on what she is eating? Lately, she has been living on vanilla wafers and ice cream. Today she did eat some soy crumbles that I had made into “sloppy joes” but she has eaten very little else. She is getting thinner…..is she ready to die? I know I’m not ready to make that decision. Her joy of lapping up ice cream keeps me going and smiling…but I know that her body is failing and time is probably near. sigh.
