Thank you very much for your replies Michelle and Freedom.

Sweetpea will stay in my room for a few days and yes, she will have dissolving stitches.
I was able to get a hold of my vet as my main concern was that PeaPod is still nursing off of her now and then. He suggested that I keep them separated for 10 days, then after that it should be fine. But after a few days, I will allow her out of the room under my strict supervision. She will be spayed on Wednesday and Friday will be my last day of work and then I have a week off. So I will be home to watch out for her.
