My sweet pregnant cat!

I am new to this site.  My sweet cat Nattie is pregnant, but I don't know how far along she is.  We were not planning for her to get pregnant, but now that she is, we want to make her comfortable and happy.  Her nipples are large and we can feel a lot of movement in her belly.  She is not very big...about 6-7 lbs.  She still plays with her toys some, but not as much as normal.  We have another cat (male/fixed) and he doesn't pick on her as much as he used to.  She is much more hungry than normal, in fact she sat under the dinning room table during Thanksgiving dinner today waiting for someone to drop food.  She never did that before, she wasn't interested in human food much. 

My kids and I made a box with a clean old blanket and she lays in it, but have no idea if she will give birth in it. 

I have had cats for years, but have never experienced cat pregnancy, so any advise would help.

Here are some pic's of her:

Thank you for the replies!  I feel almost as excited as when I had my own kids!  I don't know how old she is, I think she is just over a year.  My friend's brother asked if we wanted her and her sister because the owner could not care for them anymore, but I could only take one.  He didn't know about her care or vet history and before we knew it, she was in heat.  My kids and I were trying to remember when the tom's were stalking her outside and when she got out.  We can't remember for sure, but the weather was warmer (maybe September). 

I will get her spayed after she has her babies.  Does anyone know how long after I should wait? 

Thanks for the advise.  Since we made the box for her to lay in, should we put it in the room where I would like her to give birth?  And should I confine her to that room before she gives birth? (Of course with food, water, and a litter box)

I do have another cat that chases her, but also lays with her.  I don't know if he stresses her because she acts the same way she always does with him.  He hasn't been chasing her as much lately.  I was asking about confining her because of him, but she seems to deal with him well.

I'm pretty sure that he is playing with her.  I have seen her walk up to him and hit his tail, maybe for him to chase her.  He also licks her head and lays by her.  For the most part, they leave each other alone so I don't think she is stressed by him.  Her favorite spot to lay right now is under the dinning room table or in front of a heat vent.  She doesn't hide or act scared to be around him or us.  She acts normal becides little things like increased appetite and sleeping more.

Nattie just had one kitten, she is licking it right now!!

Kitten # 2 born!!

Now #3 is here!

Tired mama.

I have no idea what sex they are yet.  They all look the same there for now. 

Congrats on your Queen's babies!

Two girls and one boy!
