I just lost my two year old buddy to FIP four days ago, and I understand your loss and pain. It's very unexpected and I've been blaming myself too and wondering if I made the right choice. My buddy had already hit the worst from it; he had stopped eating entirely for two weeks and went from an energetic young, loving boy to suddenly a silent, sickly kitty who struggled with gathering energy to jump. He looked terrible and his liver started failing, and it was beyond awful to watch him become that. At the time I hadn't been aware it was FIP, so it was a trial-and-error period with my vet to see if different antibiotics brought his fever down, but in the end nothing helped and his liver began failing. I didn't really have a choice then because he wasn't living his life anymore, he was just there and really sick and even the look he gave me just told me that he was sick and not himself. I think it would be worse to have watched that happen in a kitten, because the entire time I just kept willing my boy to get better and wanting to help, but I really couldn't. It was awful, knowing that all I wanted to do was take care of him and bring him back to the lively kitty he was but that he was just getting worse and no matter how much I spent or did it couldn't help him. I hope someday that they find a cure for FIP so no one has to go through these ordeals ever again.
I'm really sorry about your loss. I'm really trying to remember my boy in his most positive light and how he made me smile and I won't ever forget how important he was to me. I hope you can do the same with your precious baby Ringo. At least he was happy and loved, not all young cats are so lucky to have a safe and loving home. I'm positive that you did everything you could and more for him and clearly he was loved. With FIP and my experience with it, it's just a terrible battle that has no hope for a good outcome either way.
