If there is another stillborn, and I hope not, you can also try this trick, but you have to be quick- and I mean seconds. Have a large bowl of cold water standing nearby, if the kitten is born and is unresponsive and you try the swing, and the towel with no response, you very quickly, and i mean quickly dunk the kitten in the water up and down. Like a mega fast baptism. That can shock the body and bring the kitten round. You also need dry warm towels close by to wrap the little one and get him totally dry because you shouldn't get them wet. This is a last-measure resort only-try the other two procedures first.
