What a very sad day it is, but for Sassy, she'll be released from the pain she's in and it will be nice for her to be free from her failing body. I'm so sorry that you are having to say goodbye to your friend today. I know how hard it is, the pain is still so fresh from when I had my beloved Graham PTS, but dispite all the mountains of tears, there was such relief knowing my beloved friend was free from pain. You are a very brave young lady and know that all us animal lovers are with you in spirit today and always.
