I'm confused. Were there 4
stillborn? Aww, poor Luna...this is so sad. How is the #2 kitty that is alive, is it nursing well? Did they all
come out with their placentas intact? If not, she should be checked by a vet. You don't want a retained placenta; it will cause infection; nor do you want a retained stillborn if she still has another to come---same result (pyometra). She would have to be spayed immediately and on medication. Hope that doesn't happen.
Were you abe to contact another vet, just in case?
