Thanks for all of your support and advice!
Well, my hubby and I just moved and brought her and 2 other cats with us. We have a tiny car and it was packed so I had to hold the mama and babies in my lap the whole time. During most of the rid the mama hid, but she checked on her babies every once in a while. Want to hear something cute though...
I have another cat who just lost her babies right before birth(she had to have surgery, they were too far gone and couldn't be saved) and during most of the ride she "babysat" the kittens. She still had some milk and so she would lay in the lap with the kittens and clean and nurse them, then she would go lay somewhere else in the car. At one point the mama cat came to the front seat while the other cat was nursing her babies. Instead of getting upset, she just laid down next to her and helped out, how cute is that?!? I think she appreciated the help because she was too scared to do it herself.
Anyways, we azre moved now and we keep the mama and babies in a crate and close the door at night so the mama can't hide them while we are sleeping. She seems comfy where she is though and I think she's over the "moving babies" stage. Plus, the babies are almost too big for her to move now. She's almost half the size of our other female and the other one is small too. I think she only wieghs about 4 lbs, if even that much.
