Please Help Me!!!!!! Anyone?

I foster animals all the time, and just got this sweetheart yesterday. She is pregnant, but I have no idea what to expect. She is HUGE, and I need to know when she will be ready.... I need cat expert's help! She will meow and meow and meow at night until I come pet her and give her attention. She likes to hide under my bed, and I have to really work to get her out. Any advice is appreciated!
On a side note: She is having diarrhea until she makes it to the litterbox.... but has normal stool while there.
Thanks in advance for your help!

It sounds like she's very close! Do you have a nest set up for her? Some cats have diarrhea shortly before going into labor to clean out their systems. Otherwise, it may be her system adjusting to new food she is eating with you. [emoji]128522[/emoji]
