I am sorry that your day didn't go as planned. You must remember that you are a good person for trying to do what you could for that injured cat. It was warm in a blanket and being held by loving arms when it died. PLEASE think that you did something VERY special.... it really was. It may have been difficult but you MUST feel good about yourself knowing that you did a GOOD thing. Don't let it get you down.
for doing what you could.
