You did absolutely everything you could. I couldn't have told you to do any more than what you did, the downward swing, resuscitation and chest compressions, that's all anyone could have done, and most people wouldn't have known how to do that. I am so, so sorry. It was a tragic, tragic accident.
We know how much you loved these babies and how wonderfully you took care of them. Again, I'm so sorry. They would have died long ago without you, and they would never have known love and care. Because of you, they had a fighting chance. Minnie's life was too, too short but it was happy and she was loved to bits. So many little kittens and cats never even know that.
