So for the last month I have been taking care of a stray. I had a feeling she was pregnant, and she is giving birth right now in a box we set up for her on our porch. It is going to be 29 degrees tonight, but I think the box should be warm enough. There is not to much empty space in the box. The inside has around the perimeter of it foam insullation, and there are blankets in the box, as well as around it for more insulation. So far I know she had two kittens. I am hoping she does not have anymore, but she was pretty fat in the tummy. One of my concerns is one of the kittens is sitting behind her and I dont know if I should try to put it near her belly. Should I just let nature take its course or intervene.
