hissy, I'm so sorry. I know how it feels, as I just lost my little Persian. Even though Stanley didn't die the same way, I feel like I failed my little guy also, because I should have known he wasn't well, before he got so seriously ill, and I didn't. I'll always feel like I failed my boy,because I think I didn't take good enough care of him, and the I wasn't observant enough. You trusted this experienced groomer to take proper care of your cat. I don't think you failed him at all.
