The next day I saw her sitting outside her entry hole to the shed, quite peaceful. And then two of her kittens were outside also. Then the molly went for a walk and left her two kittens outside the shed. I went inside the shed and I found the third kitten dead. It was the brown one, the weak one. I went outside again and shut the door properly and blocked the entry hole to prevent the mom from returning to the shed.

Then I put a table in my yard and covered it with a blanket and I threw some pillows and blankets under it and I built a new home for the cats. The molly hovered about, growling and acting rowdy. I put some food on plates outside their home and hoped that the molly would move in with her two surviving kittens.
Lo and behold, some hours later she had transported her kittens to their new home. I was extatic. She ate the food in the company of her kittens. Then she hung around a bit. Then she left. She was always leaving. I couldn't figure it out.
