Need some advice about a pregnant cat.?

The only thing you can help her with is to find or make her a comfortable place to give birth. I would recommend you make her a place to stay unless you want blood stains everywhere. My dog gave birth and my brother made her a box made of wood padded with old sheets and pillows so she would not bleed everywhere. When she gives birth do not go watch her it might frighten her. And do not pull the umbilical cord it will fall off. Do not touch her kittens immediately she may be defensive. And keep her area clean if not she will start eating the baby's poop when they poop. To keep clean.
