OUr cat got out around Easter and we are trying to find out when she should have the babies, and how to tell when she is in labor. PLEASE HELP US OUT! :confused:

These kittens will not go unwanted, we have already found homes for all that she has, we are just trying to find out how long she should be pregnant for and how to tell when she is close to labor. :mad:

Were you trying to breed her or what happened, I mean did she get out or what? :confused: They are normally pregnant for nine weeks !

Pregnancy (http://www.peteducation.com/article.cfm?cls=1&cat=1366&articleid=893)

What I mean by unwanted is they were not planned.Or did you plan it?

I did leave the link that tells you how long they are pregnant.
