She seems to be having egg laying trouble. I would put her into a lukewarm tub, water deep enough to float in for about an hour. It should help her relax and pass the egg. Be careful handing her so as not to break the egg in her abdomen. Longer term, get her some calcium supplements. I use 23% calcium gluconate liquid, a teaspoon per four ounces of water added to their food. I also add a little dry cat kibble that has extra vitamin D in it.
