Pregnant Cat

Hi I recently took a cat in from someone on a Facebook page who "couldn't keep it because they were moving" and they failed to tell me the cat was pregnant. When I was able to muster up the nerve to ask they said she had been outside from the 26-28th of December but they had no idea of if she had mated. They "didn't know" she was pregnant... She is OBVIOUSLY pregnant and has been somewhat changing in her mood in the fact that she is not wanting to be alone but not really wanting to be touched for 2 days now. This morning when I was checking her out I felt for milk in her breasts and a little drop of milk came out. She sleeps constantly or cleans herself and when awake she nibbles on her food but not much. When I pet her back she constantly puts her butt up in the air as though she is in heat and rubs her face on the corners of the walls. I can see the kittens moving and can feel them in her middle lower abdomen. She will only stay in the "birthing area" when I literally sit with her in it and she sleeps. How long does this normally last?!

Just to clarify, I am 100% for adoption of cats and spaying and/or neutering and plan to do so ASAP!

how long her labor should last is that what you are asking?

Honestly I have no idea if she is in labor so I suppose I'm asking if this is signs of labor?

by the sounds of it she will be within 24 or 48 hours
