Thank you for your input. I have been in cat rescue for over six years now. I have saved many, but some have been euthanized. It is a hard choice to make and one I have not done lightly. However, I will not let a cat or any other animal suffer. If and when the time comes for Sapphie, I will make the humane choice. In the meantime, I will do all I can for her. We are still waiting for the humaworm to come. I know it isn't a cure all, but I am hoping and praying it will help.
