You didn't fail her. You did everything you could, along with C to give her the best possible chance. Would C say that you failed her? I honestly don't think she could. Sometimes things are just outside our control. When Flip died whilst being neutered, I felt so guilty, but there was no way I could have known and the fact that his brother Flop survived and lived until he was pts at 7 shows that. We all want our buns to have long and happy lives, but despite our best efforts, sometimes it's just not to be. Lots of love xxx
