Cindy, I'm so sorry you are going thru this heartache. And I know it is exactly that. You feel like your heart is being ripped out of your chest. I believe that animals are wiser than people when it comes to many things. Life and death included. I think Taz will know when it's time and I think he'll tell you. Just release that decision to the Universe and it will play out as it should. I'll PM you too.
Love,
Claudia, Calvin & Hobbes
