Wolfsoul,

If your friend has a spare room, close her in there with a birthing box in a quiet, isolated place. A cardboard box lined with plastic and old towels will be fine. Cut the box so that it's easy for mama to get out but not the babies. In the room, put a litterbox, food, water, a nightlight and a radio that plays soft, classical music. Do not, if your friend has other cats, let her near them until she's been tested. Especially since the owner of the cat lied about her being fixed.

The gestation of a cat pregnancy is 42-46 days, which is difficult for your friend since she doesn't know when the cat got pregnant. Your friend will be able to tell when mama is in labor because she'll become very fidgity and her appetite will decrease. Unless there is a problem, just let nature take it's course. Once the babies are all born (they'll come out in little embryonic sacs that mama will tear open and begin cleaning the baby) just make sure mama caring for all the babies. If there seems to be a problem and she's ignoring one, you may have to bottle feed. But that's getting a little way ahead.

Keep me posted and I will try and help you as best as I can. One more thing, if mama moves the babies, that's an indication that she feels threatened. Good luck and don't panic!
