Oh my Donna! This is so sad and my heart is breaking for you. I know that what you did was best but how it does hurt, doesn't it?! I have had to make that decision myself in the past and it does, as you said, feel like your heart has been ripped from your chest. You will be in everyone's prayers for this is a loss that all of us at Pet Talk fully understand. Your post was a beautiful tribute to Casey. {{{{{HUGS}}}}} to you at this most sorrowful time. Rest in peace sweet Casey.
