I know how you feel about your delima, I was kinda in the same boat with Dusty. The day I had scheduled her for possibly being PTS was the day she stopped really eating, then I knew I'd made the right decision but constantly questioned myself, and debated on cancelling the appointment several times. I even sat and had a conversation with Dusty the week before asking her to let me know when she was ready to go.

We've all been there and know what you're feeling and how heartbreaking this is for you. I know you'll do what's best for Boo. You do pay attention and go above and beyond for your pets. Thoughts are with you.
