I got a foster cat the other day who they said is probably pregnant because the person who captured her found her with a male last week. I do not want to abort the kittens and it is not even an option for me. But she has an umbilical hernia, does anyone have experience with this? She has a doc appointment, but not until next Friday. Also, is it normal for a pregnant cat to throw up? Even though they said she is probably only a week pregnant?? She has thrown up 3 times today, but is acting fine other than that.
