1day, there are such worse things for people and animals to endure. I want you to feel good aboput the love for the kitty and the food. Death is merely a transition. I am so sorry you are feeling down. You know the old cliche, better to have loved and lost then never to be loved? The cat was loved. You are loved. There is so much suffering in the world and you fed a hungry kitty. Please feel proud of that, feel blessed to share this life with kitty. It is a gift. I wish I had a magic wand.
